UPDATED – November 2022
The laws and regulations restricting non-essential uses of pesticides in Manitoba have been changed with the adoption of legislation amending the provincial Environment Act on November 3, 2022. The amending bill received Royal Assent the same day, and is now law.
Please consult the official statute, as amended, and any associated regulations for any legal guidance you may require.
Unofficially — it appears that any pesticide approved by Health Canada for the purpose may now be used in municipal, institutional and residential lawn care. However, it appears that there are still prohibitions on using pesticides other than allowable pesticides on school grounds, hospital grounds, child care centres, municipal playgrounds, picnic areas, dog parks, and provincial parks.
