Growing Cannabis at Home

Cannabis plants are susceptible to many pests including insects, mites, fungi and bacteria. It's important to educate yourself on how to safely treat these pests with your personal health and safety in mind. These resources will provide information on how to manage pests on cannabis grown for personal use.

Using Pesticides on Residential Landscapes

Read the summary of the 2016 amendments made to the Integrated Pest Management Regulation (IPMR); intended to ensure that pesticides are used responsibly by people with knowledge and training.

As of July 1, 2016, a pesticide user licence or certificate is required to apply most pesticides to private landscapes. This includes pesticide use on lawns, flower beds and ornamental trees and plants.

There are a number of options available to residents who wish to apply pesticides to their private residential landscapes:

  • Hire a licensed service provider (for more information see the Managing Pests page).
  • Choose an appropriate pesticide from the Schedule 2 - Excluded Pesticides list. See the Schedule 2 Guidance Factsheet (PDF) for more information
  • Choose an appropriate pesticide from the Schedule 5 list (pesticides that are safe for use by untrained people). See the Schedule 5 Guidance Factsheet (PDF) for more information
  • Apply domestic class pesticides for landscape purposes if you first obtain a Residential Applicator Certificate. Note that a pesticide licence is required to apply any commercial or restricted class pesticide for landscape purposes.
    • Residents do not require a Residential Applicator Certificate for certain uses of Domestic class glyphosate. These include treating:
      • Plants that are poisonous for people to touch (e.g., poison ivy, poison oak);
      • Invasive plants and noxious weeds listed in legislation; and
      • Weeds growing through cracks in hard surfaces such as asphalt or concrete.

Note – municipal restrictions may apply. See the municipal bylaw table for more information and check with your municipality.

Notification for Tenants

A landlord with a Residential Applicator Certificate who plans to apply pesticides to outdoor landscaped areas must provide written notice to tenants.

Notification must provide information on:

  • Which pesticide will be used and where
  • When the application will occur
  • The target pest
  • Contact information (including your Residential Applicator Certificate number) and
  • If there are any safety precautions to follow
