The costliest lawn care mistakes in Canada are applying pesticides without the right licence, ignoring provincial lawn pesticide rules, and unsafe mowing.

This guide lists seven common mistakes, what Ontario, Quebec, and CCOHS say, and how to fix them before the season. It suits people mowing, trimming, and tidying residential lawns.
How to start is in the lawn care side hustle guide. Mower, trimmer, and insurance costs are in lawn care startup costs. Per-cut and seasonal rates are in lawn care pricing. The first clients are in your first lawn care clients.

Which pesticide mistakes do lawn care workers make in Canada?
The main pesticide mistake lawn care workers make in Canada is treating weed control as a simple add-on. Several provinces regulate both who may apply products and which products may be used on lawns.
Mistake 1: Applying pesticides without a licence
Ontario’s pesticide licences page says that, unless exempt, you need a pesticide exterminator licence to apply pesticides commercially on any property that you or your employer do not own or farm. Other provinces have their own licensing; check before offering spraying.
Mistake 2: Using non-permitted lawn products
Ontario’s home lawns and gardens page says cosmetic use on lawns is limited to products on the allowable list, such as borax, corn gluten meal, soap, and sulphur, with exceptions for health and safety reasons such as poison ivy, giant hogweed, wasps, and ticks. Quebec’s Pesticides Management Code also restricts lawn pesticides.
Mistake 3: Skipping required notices
Quebec’s code requires permit holders to post signs after applying pesticides to a lawn, left in place for at least 24 hours. Learn the posting rules in your province and city before any application.
Which safety and insurance mistakes do lawn care workers make in Canada?
The main safety mistake lawn care workers make in Canada is rushing: mowing wet grass, mowing up and down slopes, or reaching under a running machine.
Mistake 4: Unsafe mowing habits
The CCOHS rotary mower page says to wear hearing and eye protection, clear rocks and debris before mowing, keep people and pets away, not mow wet grass, and mow across slopes with a push mower. It also says not to unclog the chute while the mower is running and to disconnect the spark plug wire before cleaning or sharpening the blade.
Mistake 5: No liability insurance
A mower can throw a stone through a window or into a car, which can lead to a damage claim. The FCAC’s home insurance page says home insurance isn’t business insurance and generally won’t cover business claims. Ask a broker about liability coverage.
Which client and record mistakes do lawn care workers make in Canada?
The main client mistake lawn care workers make in Canada is not writing down what each visit includes.
Mistake 6: Vague service terms
State cut frequency, edging and trimming, whether clippings are bagged or mulched, what happens in rain or drought, and how missed visits are handled.
Mistake 7: No mileage or income log
The CRA’s motor vehicle records page says to keep a logbook with each business trip’s date, destination, purpose, and distance.
How do you set up lawn care to avoid these mistakes in Canada?
Set up lawn care in Canada to avoid these mistakes by deciding what you will and will not offer, sorting insurance, and writing service terms before the season.
Step 1: Decide on weed control
Offer only allowable products and methods, or refer licensed work out.
Step 2: Read your province’s pesticide pages
Licensing, allowed products, and posting rules.
Step 3: Get insurance quotes
Ask about property damage from thrown objects.
Step 4: Write service terms
Frequency, edging, clippings, weather, and missed visits.
Step 5: Set up safety gear and a route log
Hearing and eye protection, plus a logbook.
Illustrative example
This is a teaching sketch with assumed numbers, not a quote or average. Suppose you mow 15 lawns weekly for 22 weeks at $40 a cut (assumed): revenue is 15 × 22 × $40 = $13,200. If you add hand-pulled weeding at $25 per visit for 5 clients every other week (11 visits each), that adds 5 × 11 × $25 = $1,375 without any pesticide licence.

How do GST/HST and income tax affect lawn care in Canada?
Lawn care income in Canada is self-employment income reported on Form T2125. GST/HST registration is required once taxable supplies pass the $30,000 small-supplier threshold in a calendar quarter or over four consecutive quarters, across all your businesses, including winter snow work. Ear defenders and safety glasses from Amazon.ca TODO-AFFILIATE are small costs; seasonal invoices can come from FreshBooks TODO-AFFILIATE.
