Pesticides are used on our food, around our homes, and across the environment. When Canada decides one is safe enough to use, that decision matters to all of us.
But science changes. We learn more about long-term exposure, testing improves, and we discover impacts on people, wildlife, and ecosystems we didn't understand before. That's why Canada currently requires every registered pesticide to be re-evaluated at least once every 15 years.
Bill C-31 would change that. Instead of automatic full reviews, Health Canada would first look at existing information, and only trigger a full re-evaluation if risks appear to have "increased significantly." The government says this would help focus limited resources on the highest-risk pesticides.
But what if you don't know there's a problem until you actually look for it? Periodic reviews let us test old decisions against new science. Before removing that safeguard, Canadians deserve evidence the replacement will protect us just as well.
Bill C-31 hasn't passed yet. If you want Canada's pesticide rules to keep pace with changing science, there's a parliamentary petition you can sign now here: https://www.ourcommons.ca/petitions/en/Petition/Sign/e-7742
