Three Jobs, One Truck, No Paperwork
Priya manages a three-person lawn-care crew in London, Ontario. The company holds a valid Ontario exterminator licence, but Priya herself holds only a current grower certificate. A church across the road from an elementary school asks the crew to do three things: spray a Class 4 herbicide (2,4-D formulated for turf) on its front lawn to kill dandelions before a wedding, destroy a wasp nest under the eavestrough, and spray the school's chain-link fence line "to keep the weeds down." The crew's backpack sprayer holds leftover product decanted from an agricultural job into an unlabelled container. The truck carries no licence number, and the season's paperwork consists of a shoebox of fuel and parts receipts.
1. Which of the three jobs may lawfully be done, and by whom? Explain your reasoning for each.
Read the worked answer
Church lawn dandelions - refuse. Under Ontario's cosmetic pesticides rules (O. Reg. 63/09 under the Pesticides Act), Class 4 products are banned for cosmetic use. Killing dandelions to improve appearance is the definition of cosmetic use, and a wedding is not a health-or-safety purpose. Church grounds are not an exempted use site. Offering a lower-risk Class 5 product registered for that use, or mechanical/cultural control (overseeding, aeration, spot digging), are the lawful alternatives.
Wasp nest - only by a licensed exterminator. Structural pest control is exterminator work. The company licence does not authorize Priya personally; she would need an exterminator licence, and the product used must be registered for wasps and applied per its label. She should refer this job to a licensed exterminator on staff.
School fence line - refuse. School property is subject to the cosmetic ban; routine vegetation control for appearance is cosmetic. An exemption (e.g., a declared noxious weed or a documented health hazard) requires the specific legal basis, not a verbal request.
Common thread: legality turns on purpose and site, not on whether a product is 'agricultural' or 'domestic'.
2. What is wrong with the sprayer's contents and the missing licence number, and what must happen before the crew does any work this season?
Read the worked answer
Unlabelled container. A pesticide must be kept in its original container with the label intact, or in a container bearing the required information. Decanting into an unlabelled sprayer is an offence and is also an outright safety failure: no one can read the rate, the PPE, the re-entry interval, or the first-aid directions. The contents must be treated as unknown: do not spray them out, do not dump them. Identify them if possible and dispose of them through a licensed waste receiver or an approved collection program, then triple-rinse and decontaminate the sprayer.
Missing licence number. Licensing rules require the licence number to appear in the company's advertising/identification. The fix is administrative but the exposure is real - a complainant, the municipality, or a provincial inspector will start with what is visible on the truck.
Before any application:
- Confirm each crew member's actual authorization (grower certificate vs. exterminator licence) against the work being sold.
- Verify each job's site class and purpose against the regulation.
- Rebuild record-keeping: site, date, time, product name and registration number, rate, area treated, applicator, and weather at application.
- Confirm the company's pesticide storage is compliant (locked, ventilated, secondary containment, no product in food or drink containers).
3. The church insists the dandelion spray is harmless and offers to sign a waiver. Can the crew proceed on that basis? What are the realistic consequences if they do?
Read the worked answer
No. A private waiver cannot create authority that the statute does not give. Regulatory prohibitions are not waivable by a client, and a waiver would not protect the company, the applicator, or Priya personally.
If they proceed anyway:
- It is an offence under the Pesticides Act; penalties and compliance orders attach to the company, the supervisor, and the applicator.
- The company's exterminator licence is the business's livelihood - a conviction or order puts it at risk.
- Insurance coverage can be denied for work that was unlawful from the outset.
- The visible facts (school across the road, truck with no licence number, unlabelled sprayer) make detection likely if anyone complains; drift onto school property adds a separate exposure pathway.
Professional response: decline in writing, document what was offered instead, and provide the client a written summary of the lawful options. If the church believes a health-or-safety exemption applies, the crew should require the documented basis before re-quoting the job.
