Question 5Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A company that offers structural pesticide application services to the public for a fee must hold which licence?

  1. A pesticide applicator licence
  2. A pesticide vendor licence
  3. A pesticide operator licence Correct answer.
  4. A ministry business registration number

Explanation

A pesticide operator licence is issued to a business that applies pesticides for hire or compensation. Individual employees must still hold their own applicator licences.

Question 6Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

What must an applicant do to obtain a pesticide applicator licence in Ontario?

  1. Complete a two-year apprenticeship
  2. Post a bond with the ministry
  3. Pass the ministry's certification examination Correct answer.

Question 7Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A homeowner asks an operator to spray a herbicide on the front lawn to remove dandelions. What should the operator do?

  1. Apply it if the homeowner signs a waiver
  2. Apply it after notifying the municipality
  3. Decline; cosmetic lawn use is prohibited Correct answer.
  4. Apply it after giving 24 hours' written notice

Explanation

Ontario's cosmetic pesticides ban prohibits using pesticides to maintain the appearance of lawns, gardens and similar landscaped areas. Neither a client waiver nor notice to the municipality creates an exemption.

Question 8Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which use of a pesticide is allowed under Ontario's cosmetic pesticides ban?

  1. Controlling moss on a driveway
  2. Controlling poison ivy where children play Correct answer.
  3. Controlling clover on a home lawn
  4. Controlling dandelions on a municipal park lawn

Explanation

The regulation exempts the control of plants that are poisonous to humans by touch, such as poison ivy, poison oak and poison sumac. Controlling dandelions, clover or moss for appearance is cosmetic and prohibited on the covered lands.

Question 9Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

For how long must a licensed pesticide operator keep records of pesticide applications?

  1. One year
  2. Ten years
  3. Two years
  4. Five years Correct answer.

Explanation

Ontario Regulation 63/09 requires application records to be kept for at least five years. The records must be produced when a provincial officer asks for them.

Question 10Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which statement best describes the legal effect of a pesticide label in Ontario?

  1. Label directions apply only to unlicensed users
  2. Label directions may be replaced by the operator's written procedure
  3. Label directions are enforceable and use must comply with them Correct answer.
  4. Label directions are advice the applicator may adjust

Explanation

Pesticides are registered with label directions under federal law, and Ontario law makes it an offence to use a product in a manner inconsistent with those directions. Rates, application sites, target pests and protective equipment set out on the label are therefore binding.

Question 11Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

How should a structural applicator keep pesticides on site between treatments?

  1. In any sturdy container marked with the product name
  2. In a locked glove box with the licence
  3. In a sealed plastic bag with a copy of the label
  4. In the original container bearing the registered label Correct answer.

Explanation

Pesticides must be kept in the original container with the registered label attached so the product and its directions stay identifiable. Decanting into unmarked or partly labelled containers is not permitted.

Question 12Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

About four litres of concentrated insecticide spill onto a loading dock during a treatment. What must the operator do?

  1. Report it immediately to the Spills Action Centre Correct answer.
  2. Record the spill in the application log only
  3. Notify the municipality at year end
  4. Wait until the monthly report to the ministry

Explanation

A pesticide spill must be reported immediately to the ministry's Spills Action Centre, and the municipality and affected persons must also be notified. The operator must contain and clean up the spill and keep it out of sewers and watercourses.

Question 13Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

An unlicensed assistant is helping a licensed applicator during a structural treatment. What is required?

  1. Carry a copy of the operator's licence
  2. Keep a personal log of every application
  3. Work only under direct licensed supervision Correct answer.
  4. Apply products only inside empty buildings

Explanation

An unlicensed person may use pesticides only while working under the direct supervision of a licensed applicator, typically as part of training. The licence and its responsibilities stay with the licensed applicator.

Question 14Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A provincial officer arrives at a pest control business and asks to see application records and the storage room. What is the appropriate response?

  1. Refuse unless the officer produces a warrant
  2. Provide access to records and the storage area Correct answer.
  3. Direct the officer to the ministry website
  4. Provide records for the current year only

Explanation

Provincial officers appointed under the Pesticides Act may enter and inspect premises and require production of records without a warrant. Refusing access or obstructing an officer is itself an offence.

Question 15Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A firm plans to fumigate a warehouse with a fumigant gas. Besides the firm's operator licence, the person carrying out the fumigation needs:

  1. A pesticide vendor licence
  2. A forestry applicator licence
  3. A fumigation applicator licence Correct answer.
  4. A water applicator licence

Explanation

Fumigation is a separate applicator licence class in Ontario because of the added hazards of fumigant gases. A person licensed only for structural work is not authorized to conduct fumigations.

Question 16Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Before a pesticide may legally be sold or used in Canada, it must have:

  1. A PCP registration number Correct answer.
  2. A provincial classification number
  3. An operator licence number
  4. A municipal business permit

Explanation

The federal Pest Control Products Act requires every pesticide sold or used in Canada to be registered, which gives it a PCP registration number and an approved label. Ontario then classifies the product and controls who may sell or use it.

Question 17Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which statement about an Ontario pesticide applicator licence is correct?

  1. It is valid only for the licensee named on it Correct answer.
  2. It may be lent to another employee of the same company
  3. It expires whenever the licensee changes employers
  4. It may be transferred if the operator files a form

Explanation

An applicator licence is issued to a named individual and authorizes only that person to apply pesticides in the classes shown. Lending it to another worker, even within the same company, is an offence.

Question 18Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which item must appear in an application record kept by a licensed structural operator?

  1. The client's method of payment
  2. The applicator's home address
  3. The brand of spray equipment used
  4. The product name and PCP number Correct answer.

Explanation

Records must identify the product used, including its name and PCP registration number, along with the date, location, quantity, target pest and applicator. Personal details such as payment method or equipment brand are not required.

Question 19Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A licensed vendor may sell a Class 2 pesticide to:

  1. A person holding a valid pesticide licence Correct answer.
  2. A homeowner with written label instructions
  3. Any adult who signs the vendor's purchase log
  4. A person who has completed a safety course

Explanation

Restricted-class products may be sold only to persons who hold the appropriate pesticide licence or permit. Selling to an unlicensed buyer, even where a purchase log is signed, is an offence for the vendor.

Question 20Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

An operator is charged after an employee applies a product at double the labelled rate. Which defence is legally available?

  1. The operator took all reasonable steps to prevent it Correct answer.
  2. The client requested the higher application rate
  3. The employee acted without the operator's knowledge or consent
  4. The employee had not read the label

Explanation

Provincial offences are generally strict liability offences, so the accused may avoid conviction by proving due diligence, meaning all reasonable steps were taken to prevent the offence. Blaming the employee or the client does not by itself answer the charge.

Question 21Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

An Ontario pesticide applicator licence remains valid for how long before renewal is required?

  1. Ten years
  2. Five years Correct answer.
  3. One year
  4. Three years

Explanation

Pesticide licences issued in Ontario are valid for five years from the date of issue. Working after the expiry date means working without a licence.

Question 22Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

After treating a client's building, the client asks for a copy of the application record. What should the operator do?

  1. Provide it only after the licence is renewed
  2. Refuse, because records belong to the ministry
  3. Provide a copy of the record to the client Correct answer.
  4. Charge the fee set by the ministry

Explanation

The operator must make the application record available to the client on request while keeping the original for the required retention period. Delaying the copy until licence renewal has no basis in the regulation.

Question 23Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

What determines the protective equipment a structural applicator must wear while applying a pesticide?

  1. The pesticide label directions Correct answer.
  2. The client's written preference
  3. The local municipal by-law
  4. The operator's internal written policy

Explanation

The label states the minimum protective clothing and equipment for the product, and those directions must be followed. Workplace safety law may require additional protection but cannot reduce what the label requires.

Question 24Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which statement best describes how federal and provincial pesticide rules work together in Ontario?

  1. Both levels register products and license users
  2. The federal government licenses applicators; Ontario classifies products
  3. Ottawa registers products; Ontario licenses users and restricts use Correct answer.
  4. Ontario registers pesticide products; the federal government licenses users

Explanation

The federal Pest Control Products Act registers products and approves their labels, while Ontario classifies products, licenses users and can add restrictions such as the cosmetic pesticides ban. Both sets of rules apply at the same time.

Question 25Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

The ministry suspends a company's pesticide operator licence. During the suspension the company may:

  1. Continue working only for existing clients
  2. Apply pesticides only with written client consent
  3. Continue working if a licensed applicator is on staff
  4. Not apply pesticides until the suspension is lifted Correct answer.

Explanation

A suspended operator licence authorizes no pesticide application work for the business. Applying pesticides while suspended is an offence, and staff holding applicator licences do not restore the company's authority to operate.

Question 26Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A homeowner wants to apply a rodenticide bait inside their own house to deal with a mouse infestation. What licensing requirement applies to this use?

  1. An applicator licence is required, because rodenticides are restricted to licensed persons
  2. A ministry permit is required, because the treatment is inside a dwelling
  3. A vendor licence is required, because the product is purchased at retail
  4. No applicator licence is required, because the product is being used by the owner on their own property Correct answer.

Explanation

Ontario's licensing scheme is aimed at persons who apply pesticides for hire or on property they neither own nor occupy. An owner or occupant applying a pesticide on their own property, for their own purposes and not for payment, does not need an applicator licence. The label directions and any applicable restrictions on cosmetic use still apply.

Question 27Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Which regulation under the Pesticides Act sets out Ontario's licensing requirements, permit rules and pesticide classifications?

  1. The Pest Control Products Regulations
  2. Ontario Regulation 63/09 (General) Correct answer.
  3. The Ontario Fire Code
  4. Regulation 347 under the Environmental Protection Act

Explanation

Ontario Regulation 63/09 is the general regulation made under the Pesticides Act and it contains the licensing, permit, classification and record-keeping requirements that apply in the province. The Pest Control Products Regulations is a federal instrument made under the Pest Control Products Act, and Regulation 347 deals with waste management.

Question 28Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

Under Ontario's pesticide licensing scheme, an operator licence is issued to which of the following?

  1. A retail outlet that sells pesticides directly to the public
  2. A business that performs applications in its licensed classes Correct answer.
  3. A property owner who contracts out pest control work
  4. An individual who personally applies pesticides in the field

Explanation

The operator licence is held by the business that carries out pesticide applications, and it is issued for one or more licence classes that define the type of work permitted. Individual field applicators must separately hold applicator licences, and businesses that sell pesticides need a vendor licence.

Question 29Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

What is the practical effect of the class a pesticide is assigned under Ontario Regulation 63/09?

  1. It sets the maximum residual period allowed after an indoor application
  2. It controls who may sell or use it and under what conditions Correct answer.
  3. It fixes the price category at which vendors may sell the product
  4. It determines which federal department registers the product for sale

Explanation

Ontario places pesticides into numbered classes, and the class governs how a product may be sold and used, including whether a vendor licence, operator licence, applicator licence or permit is needed. Registration of the product itself is a separate federal function carried out under the Pest Control Products Act.

Question 30Pesticide Legislation, Licensing and Regulatory Compliance (Ontario Pesticides Act and related regulations)

A licensed technician wants to tank-mix two insecticides in a single sprayer to treat cockroaches in a restaurant kitchen. What does Ontario law require in this situation?

  1. The mixture is permitted if the restaurant owner gives written consent to the practice before work begins
  2. The mixture is allowed whenever both of the products belong to the same Ontario pesticide class
  3. The mixture is allowed only if the operator records it as a single application in the log
  4. Both product labels must permit the mixing, and the mix must be applied as labelled Correct answer.

Explanation

A pesticide may only be used in accordance with its label, and tank mixing is permitted only where the label directions allow mixing and each product is registered for the pest and site being treated. Applying a combination that the labels do not authorize is a contravention, regardless of consent or record-keeping.

Question 31Pesticide Labels, Safety Data Sheets and Product Information

On a Canadian pesticide label, which signal word indicates the product with the greatest acute hazard?

  1. WARNING
  2. DANGER Correct answer.
  3. NOTICE
  4. CAUTION

Explanation

Pesticide labels use a graded set of signal words, with DANGER (often paired with the word POISON and a skull and crossbones symbol) reserved for the most acutely hazardous products. WARNING is used for products of moderate hazard, and CAUTION for those of lower hazard, so the ranking runs DANGER, then WARNING, then CAUTION.

Question 32Pesticide Labels, Safety Data Sheets and Product Information

A pesticide label displays a skull and crossbones symbol. What hazard does this symbol communicate?

  1. Flammable solid
  2. Acute toxicity, which may be fatal Correct answer.
  3. Oxidizing liquid
  4. Corrosive to skin

Explanation

The skull and crossbones denotes acute toxicity, meaning the product can be fatal or seriously harmful if swallowed, inhaled, or absorbed through the skin. On Canadian pesticide labels it is commonly shown together with the word POISON.

Question 33Pesticide Labels, Safety Data Sheets and Product Information

How many sections does a WHMIS 2015 compliant Safety Data Sheet contain?

  1. 8
  2. 12
  3. 24
  4. 16 Correct answer.

Explanation

The WHMIS 2015 SDS format follows the GHS structure of 16 fixed sections, numbered 1 through 16. The order is standardized so a reader can find the same type of information in the same place on every SDS.

Question 34Pesticide Labels, Safety Data Sheets and Product Information

Which SDS section describes what to do if a worker is overcome by fumes from a product?

  1. Section 7 - Handling and storage
  2. Section 11 - Toxicological information
  3. Section 2 - Hazard identification
  4. Section 4 - First-aid measures Correct answer.

Explanation

Section 4 of the SDS gives the first-aid measures for each route of exposure, such as inhalation, skin contact, and eye contact. Section 11 explains the health effects of exposure but does not give the emergency treatment steps.

Question 35Pesticide Labels, Safety Data Sheets and Product Information

What does the 'PCP Reg. No.' printed on a Canadian pesticide label identify?

  1. The batch or lot number assigned at manufacture
  2. The concentration of active ingredient in the product
  3. The Ontario pesticide class assigned under provincial law
  4. The federal registration number issued by the PMRA Correct answer.

Explanation

The Pest Control Products Act registration number is issued by the Pest Management Regulatory Agency when a product is registered for sale and use in Canada. Its presence shows the product and its label have been reviewed and accepted federally.

Question 36Pesticide Labels, Safety Data Sheets and Product Information

Where on a pesticide label would an applicator find the correct rate and method for mixing a product?

  1. The guarantee statement
  2. The net contents statement
  3. The registrant's warranty
  4. The directions for use Correct answer.

Explanation

The directions for use give the approved rates, dilution instructions, sites, and application methods for the product. Following these directions is both a legal requirement and the basis for safe, effective use.

Question 37Pesticide Labels, Safety Data Sheets and Product Information

A technician needs to know the occupational exposure limit and the glove and respirator requirements for a concentrate. Which SDS section provides this?

  1. Section 6 - Accidental release measures
  2. Section 8 - Exposure controls and PPE Correct answer.
  3. Section 7 - Handling and storage
  4. Section 9 - Physical and chemical properties

Explanation

Question 38Pesticide Labels, Safety Data Sheets and Product Information

A supervisor asks for the flash point, pH and appearance of a pesticide concentrate. Which SDS section holds these data?

  1. Section 11 - Toxicological information (health effects)
  2. Section 9 - Physical and chemical properties Correct answer.
  3. Section 6 - Spill procedures
  4. Section 10 - Stability and reactivity

Explanation

Section 9 reports the physical and chemical properties, including appearance, odour, pH, flash point, and solubility. These values help predict fire risk, mixing compatibility, and safe storage conditions.

Question 39Pesticide Labels, Safety Data Sheets and Product Information

A label states that people must not enter a treated room for 12 hours after application. What does this statement require?

  1. Keep people out for 12 hours unless they wear the label-specified PPE Correct answer.
  2. Apply the product only during the first 12 hours of the day
  3. Hold the product in the room for 12 hours before removing it
  4. Wait 12 hours before applying the product again to the room

Explanation

This is a restricted entry interval: it sets the time after application during which entry is prohibited unless the person wears the protective equipment the label specifies for early re-entry. The interval protects occupants from residue exposure while the product dissipates.

Question 40Pesticide Labels, Safety Data Sheets and Product Information

Where on a WHMIS 2015 Safety Data Sheet is the 24-hour emergency telephone number found?

  1. Section 1 - Identification Correct answer.
  2. Section 8 - Exposure controls and PPE
  3. Section 4 - First-aid measures
  4. Section 16 - Other information

Explanation

Section 1 identifies the product and the supplier, and includes the emergency telephone number to call for a spill, fire, or poisoning. It is the first place to look when an emergency contact is needed quickly.

Question 41Pesticide Labels, Safety Data Sheets and Product Information

An employer's written procedure says no respirator is needed, but the product label requires one for the task. What should the technician do?

  1. Follow the label and wear the respirator required by the label Correct answer.
  2. Ask a co-worker which practice they normally follow
  3. Follow the employer procedure because the employer sets site rules
  4. Apply the product without a respirator and report it afterwards

Explanation

Label directions are legally binding and set the minimum protection required; an employer's procedure cannot authorize less protection than the label requires. Where a workplace document is less protective, the label governs.

Question 42Pesticide Labels, Safety Data Sheets and Product Information

How should a structural applicator store a pesticide between jobs?

  1. In the original labelled container, locked and away from food Correct answer.
  2. In any sturdy container that is clearly marked with a warning symbol
  3. In a sealed container in the vehicle's glove box for quick access
  4. In a locked cabinet together with first-aid supplies

Explanation

Labels require pesticides to be kept in their original, labelled container, in a locked area that is out of reach of children and separated from food, drink, and feed. Keeping the original label attached ensures anyone who finds the product can identify it and read the safety information.

Question 43Pesticide Labels, Safety Data Sheets and Product Information

A storage room holding pesticide concentrates catches fire. Which SDS section tells firefighters which extinguishing media to use and what protective equipment is needed?

  1. Section 6 - Accidental release measures
  2. Section 10 - Stability and reactivity
  3. Section 13 - Disposal considerations
  4. Section 5 - Fire-fighting measures Correct answer.

Explanation

Question 44Pesticide Labels, Safety Data Sheets and Product Information

An SDS classifies a product as causing skin irritation and serious eye irritation. Which WHMIS 2015 pictogram appears for these hazards?

  1. Exclamation mark Correct answer.
  2. Flame
  3. Gas cylinder
  4. Skull and crossbones

Explanation

The exclamation mark pictogram is used for hazards such as skin irritation, eye irritation, and respiratory irritation. More severe outcomes, such as acute toxicity or corrosion, carry their own distinct pictograms.

Question 45Pesticide Labels, Safety Data Sheets and Product Information

A jug of concentrate tips over in the back of a truck. Which SDS section gives containment and cleanup methods for this type of release?

  1. Section 12 - Ecological information (environmental effects)
  2. Section 7 - Handling and storage
  3. Section 6 - Spill and release measures Correct answer.
  4. Section 4 - First-aid measures

Explanation

Section 6 gives the precautions, containment methods, and cleanup procedures for accidental releases, including how to prevent the material from entering drains or waterways. It is the section to read before starting spill cleanup.

Question 46Pesticide Labels, Safety Data Sheets and Product Information

Concentrate splashes into a technician's eye. What is the correct response?

  1. Flush for 15 minutes with water, get medical attention and take the label Correct answer.
  2. Flush the eye briefly with water and finish the shift before seeking care
  3. Neutralize the eye with a chemical eyewash recommended by a co-worker
  4. Wait to see whether irritation develops before flushing the eye

Explanation

The label's first-aid statement tells you what to do and for how long; for eye contact it typically requires prolonged flushing with clean water and immediate medical attention. Taking the label or SDS to the treating physician gives them the product's hazard information.

Question 47Pesticide Labels, Safety Data Sheets and Product Information

A reviewer needs to know when a Safety Data Sheet was last revised and what changed. Which section contains this?

  1. Section 16 - Other information Correct answer.

Question 48Pesticide Labels, Safety Data Sheets and Product Information

What information does the Guarantee statement on a Canadian pesticide label provide?

  1. The net quantity of product in the container as required by the labelling regulations
  2. The concentration of each active ingredient in the product Correct answer.
  3. The name and address of the registrant
  4. The lot number and date of manufacture

Explanation

The Guarantee states the identity and concentration of each active ingredient, usually as a percentage or grams per litre, and is the manufacturer's assurance of composition. It allows an applicator to compare products and to calculate how much active ingredient is being applied.

Question 49Pesticide Labels, Safety Data Sheets and Product Information

A label gives a rate of 10 mL of concentrate per litre of spray solution. The sprayer tank holds 4 L. How much concentrate is needed to fill the tank at the labelled rate?

  1. 10 mL
  2. 20 mL
  3. 40 mL Correct answer.
  4. 400 mL

Explanation

The rate is 10 mL for every litre, so a 4 L tank requires 4 multiplied by 10 mL, which is 40 mL of concentrate. Applying at a higher rate than the label allows is both unsafe and an offence.

Question 50Pesticide Labels, Safety Data Sheets and Product Information

Which statement best describes the legal status of a pesticide label in Canada?

  1. It is advisory, and only the SDS has legal force
  2. It is a general guide; applicators may vary rates to suit site conditions
  3. It is enforceable only when the product is used on agricultural crops
  4. It is legally binding; use inconsistent with its directions is an offence Correct answer.

Explanation

Under the Pest Control Products Act, a pesticide must be used in accordance with the directions on its registered label; use that is inconsistent with the label is an offence. The SDS supports the label with hazard information but does not authorize uses or rates.
