1Under the Ontario Pesticides Act and O. Reg. 63/09, which of the following best describes the cosmetic pesticide ban?

A.It prohibits the use of certain pesticides for aesthetic purposes on lawns, gardens, parks, and schoolyards.

B.It bans the use of all chemical and biological pesticides on golf courses and agricultural lands.

C.It allows the unrestricted use of commercial pesticides on residential lawns as long as signs are posted.

D.It regulates the manufacture of cosmetic products like perfumes and lotions containing organic ingredients.

Explanation: Ontario's cosmetic pesticide ban, established under O. Reg. 63/09, restricts the application of non-allowable pesticides for purely aesthetic or cosmetic purposes on turf and ornamental areas. Exemptions exist for specific sectors like agriculture, forestry, golf courses, and health and safety.

2Which of the following active ingredients is found on the Ontario 'Allowable List' of pesticides authorized for cosmetic uses?

A.2,4-D (2,4-Dichlorophenoxyacetic acid)

B.Glyphosate

C.Iron chelate (FeHEDTA)

D.Carbaryl

Explanation: Iron chelate (FeHEDTA) is a low-risk active ingredient listed on Ontario's Allowable List, meaning it can be legally used for cosmetic weed control on turf. 2,4-D, glyphosate, and carbaryl are restricted for cosmetic lawn/garden care.

3A homeowner has an infestation of poison ivy along their property fence. Which statement is correct under O. Reg. 63/09?

A.Pesticides may be applied to control poison ivy under the public health and safety exception.

B.Only mechanical removal is permitted; no herbicides can be used because it is a residential property.

C.Herbicides may be used only if they contain active ingredients from the cosmetic Allowable List.

D.A pesticide application is allowed only if the homeowner obtains a written permit from the municipal council.

Explanation: Controlling plants that are poisonous to the touch, such as poison ivy or giant hogweed, is exempted from the cosmetic ban under the public health and safety exception. This allows the use of conventional herbicides (like glyphosate) specifically to manage this public health risk.

4To use conventional pesticides on a golf course in Ontario, what regulatory requirement must the golf course meet under O. Reg. 63/09?

A.The golf course must be accredited for Integrated Pest Management (IPM) by an approved body and publish annual pesticide use reports.

B.The golf course must close to the public for 48 hours following any pesticide application.

C.Applications can only be performed by the head golf course superintendent using domestic-class products.

D.The golf course must obtain a site-specific environmental compliance approval (ECA) for every spray event.

Explanation: Golf courses are excepted from the cosmetic pesticide ban on the condition that they obtain and maintain IPM accreditation from a recognized auditing body and prepare an annual report summarizing pesticide use, which must be made available to the public.

5What colour is the public notice sign required for pesticide applications on a residential area lawn under Ontario Regulation 63/09?

A.Yellow

B.Green

C.Red

D.Blue

Explanation: Under O. Reg. 63/09, a green 'Notice' sign (Sign C) is required for residential area land exterminations when only Allowable List active ingredients are used. A red 'Warning' sign (Sign D) is required when other pesticides are applied. The color indicates the pesticide type, not the area type.

6For a pesticide application on a non-residential lawn (e.g., a commercial shopping center lawn), where and when must the pesticide notification signs be posted?

A.At all main access points to the property, immediately before the application starts, and left for at least 48 hours after completion.

B.Only at the property corners, 24 hours in advance, and removed immediately after spraying.

C.Directly in the center of the treated area, 12 hours after the application, and left for 7 days.

D.At the entrance of the exterminator's office and kept on display for the entire spraying season.

Explanation: Under O. Reg. 63/09, non-residential area signs (Sign E for Notice or Sign F for Warning) must be posted at main access points to the property immediately before the application. Signs must remain for at least 48 hours after the extermination is complete, and must be removed no more than 10 days after completion.

7Which of the following scenarios is an example of an exception to the cosmetic pesticide ban for 'specialty turf'?

A.A home lawn bowling green or a professional cricket pitch.

B.A residential backyard turf lawn used for family recreational sports.

C.The turf surrounds of a municipal swimming pool complex.

D.A commercial office park lawn where employees eat lunch.

Explanation: Specialty turf exceptions under O. Reg. 63/09 cover highly specialized turf surfaces that require professional-grade management to function, such as lawn bowling greens, cricket pitches, and tennis court turf. Backyards and general municipal/office lawns do not qualify.

8Under O. Reg. 63/09, what must a residential area green 'Notice' sign (Sign C) display on its front face?

A.The word 'NOTICE' in green letters, the product used, the date applied, and a contact number for information.

B.The word 'POISON' with a skull and crossbones symbol, the SDS sheet, and emergency hospital coordinates.

C.The word 'WARNING' in red letters, a person silhouette in a red circle, and the exterminator's home address.

D.A list of alternative mechanical weed control tools and a lawn fertilizer schedule.

Explanation: Sign C (residential Notice) must display 'NOTICE' in capital green letters at least 2.5 cm high, along with fields for product used, registration number, pest, application area, date applied, and an information contact number. It is used when only Allowable List active ingredients are applied.

9Which pesticide class system was adopted in Ontario's 2020 regulatory amendments to harmonize with federal registration?

A.Classes A, B, C, D, and E

B.Classes 1 through 11

C.Schedule I, II, and III

D.Categories Red, Yellow, and Blue

Explanation: Ontario's 2020 amendments aligned provincial classifications with Health Canada's PMRA federal categories: Class A (Manufacturing), Class B (Restricted), Class C (Commercial), Class D (Domestic). Class E is an Ontario-specific class for neonicotinoid-treated seeds.

10An arboriculture company wants to spray a mature oak tree on a residential lawn to control an outbreak of gypsy moth (Ldd moth) that threatens the survival of the tree. Is this allowed under Ontario law?

A.Yes, under the arboriculture exception, to maintain the health of a tree that is threatened by pests.

B.No, the cosmetic ban forbids all pesticide applications on trees located on residential land.

C.Yes, but only if the chemical is injected into the soil or trunk; foliar sprays are never permitted.

D.No, Ldd moth is a cosmetic issue and cannot be treated with any commercial-class pesticides.

Explanation: Ontario's cosmetic ban includes an exception for arboriculture, permitting pesticide applications to trees to protect their health or survival from pests (such as Ldd/gypsy moth or emerald ash borer), provided specific application guidelines are followed.

Ontario Pesticide Landscape Exam Study Tips from Top Performers

1Prepare tabs for your Landscape category manual to quickly navigate to the calibration formulas, turf weed identification keys, and cosmetic ban sign requirements during the open-book exam.

2Thoroughly understand calibration math. Practice calculating required pesticide amounts, nozzle outputs, and travel speeds using standard metric units.

3Learn the exceptions under O. Reg. 63/09. Questions will ask about situations where cosmetic ban exemptions apply (e.g. poison ivy control, golf course IPM accreditation).

4Memorize the public notification sign requirements: Green 'Notice' signs (Signs C/E) for Allowable List pesticides vs. red 'Warning' signs (Signs D/F) for other pesticides; residential signs (C/D, 28x22 cm) are smaller than non-residential signs (E/F, 51x38 cm).

5Study insect life cycles, specifically when turf pests like white grubs or hairy chinch bugs are most vulnerable to treatment.

Frequently Asked Questions

How many questions are on the Ontario Landscape Pesticide module exam?

The Landscape Specific Module exam consists of 50 multiple-choice questions, is open-book, and has a time limit of 1.5 hours. To obtain certification, you must also pass the 50-question closed-book Core exam (1 hour).

What is the passing score for the Ontario Landscape Pesticide certification?

Candidates must achieve a minimum score of 75% on both the Core exam and the Landscape Specific Module exam.

What are the rules regarding the cosmetic use of pesticides in Ontario landscapes?

Ontario Regulation 63/09 prohibits the use of pesticides for cosmetic (aesthetic) purposes on lawns, gardens, parks, and school yards. Only low-risk active ingredients listed on the provincial Allowable List (e.g., iron chelate, soaps, acetic acid) may be used for general cosmetic turf care. Applications of other pesticides require exceptions, such as public health (controlling stinging insects, poison ivy), agriculture, forestry, golf courses, public works, and specialty turf, and must follow strict conditions.

What fees are associated with the Ontario Landscape Exterminator certification?

The initial training package through OPT&C (which includes the Core manual, Landscape module manual, and one sitting of both exams) costs CAD $214. If you fail a part, rewriting that exam costs CAD $82. Once you pass both, the 5-year MECP Exterminator Licence costs CAD $90.

Do I need to do calculations on the Ontario Landscape Pesticide exam?

Yes. Calibration mathematics is a significant portion of the Landscape Module exam. You will need to calculate area, boom sprayer output, nozzle flow rate, travel speed, granular spreader delivery rate, and pesticide mixing dilutions.
