Hidden inside two budget bills is the biggest rollback of pesticide protections Canada has seen in a generation. There was no major announcement, just a quiet burial in the Spring Economic Update 2026 Implementation Act (Bill C-30) and Budget 2025 Implementation Act, No. 2 (Bill C-31).

If you missed it, that’s exactly the point.

For more than twenty years, Canada’s Pest Control Products Act (PCPA) has operated on a simple, sensible premise: health and environment come first. When the law was introduced in 2002, then-Health Minister Anne McLellan was crystal clear about its goals that it must tighten health and environmental protection, make decisions more transparent, and keep tabs on chemicals after they hit the market.

Now the government wants to rewrite that mandate. Here’s what’s actually at stake.

Science is being sidelined for “economic security”

Right now, if the science shows a pesticide poses unacceptable risks to people or the environment, the Health Minister can restrict or reject it. Under the proposed changes, Cabinet could override those science-based decisions.

The trigger? Vague, undefined concepts like “national economic security,” “regional economic security,” or “national food security.” These terms aren’t defined in the legislation, meaning politicians could essentially greenlight harmful chemicals behind closed doors without clear standards.

That’s a radical departure from how things work today. Currently, emergency use of pesticides is tightly controlled: there must be evidence that health and environmental risks are acceptable and the product actually solves an emergency pest problem. The government has produced zero evidence that our existing scientific review process threatens food or economic security. Now they are giving themselves the power to bypass it.

The Health Minister’s job description is changing

There is another subtle but seismic shift in the proposed changes: the Health Minister would be required to weigh economic and food security when deciding whether to register a pesticide.

The current law already acknowledges economics but with a critical guardrail. Today, sustainability and environmental health sit at the center because we recognize that long-term economic success depends on clean water, healthy soil, and thriving ecosystems.

Under the new rules, those economic considerations will more greatly influence the Health Minister’s decisions. It’s a quiet rewrite of the decision-making hierarchy, and it opens the door to approving chemicals that make short-term profits while creating long-term damage.

Your 15-year safety check is disappearing

Since 2002, every registered pesticide has faced a mandatory re-evaluation at least every 15 years. The logic is obvious: science advances, usage patterns shift, and long-term harms often take years to reveal themselves. Mandatory cyclical reviews ensure that “acceptable risk” stays rooted in current evidence, not outdated studies.

The government now wants to replace mandatory re-evaluations with an undefined “assessment” every 15 years. This matters because during a re-evaluation, the Minister can demand up-to-date scientific data from the pesticide company and pull in federal and provincial experts.

Under the proposed “assessment,” the government only looks at “available information.”

An “assessment” without any definition as to what is being assessed could easily conclude there’s no need for a full review, kicking the can down the road and delaying proper scrutiny. It turns a hard legal deadline into a discretionary paperwork exercise and one that lets old, potentially dangerous chemicals stay on shelves — and in our food and forests — longer.

The food security myth

Industry groups have been lobbying for years to get “economic impacts” coded into regulatory decisions. They’ve found their opening: public anxiety over food prices.

The argument is that restricting pesticides threatens food security and raises grocery bills. It’s a convenient narrative. It’s also largely false.

UN food access experts have rejected the idea that heavy pesticide use is necessary for food access or inherently lowers food costs. In reality, pesticides are an added cost to farmers and food systems. Canada’s dependence on imported, fossil fuel-derived pesticides creates supply chain vulnerabilities rather than solving them. And while industry claims we need these chemicals to feed people, they’re busy undermining the pollinators responsible for roughly 35 per cent of the global food supply, not to mention polluting agricultural land with persistent chemicals like PFAS, benzene, and dioxins.

The real threat to long-term food security is the degradation of the ecosystems we rely on: soil biology, pollinators, fungi, and clean water. You can’t prioritize “food security” while poisoning the biological foundation of agriculture.

What happens now?

For two decades, Canada’s pesticide regime has been built on a health-and-environment-first foundation. These budget-bill amendments would replace a health-and-environment first foundation with one of political discretion, undefined economic loopholes, and weaker post-market oversight.

The government is counting on the public not pushing back with all the other attacks on environmental policy currently underway.

Prove them wrong.

These amendments haven’t passed yet. Parliament still has a chance to strip them from Bills C-30 and C-31 and keep Canada’s pesticide regulations anchored in science rather than vague political convenience.

Take action today. Because if we let the largest pesticide overhaul in a generation slip through unnoticed, we won’t get those protections back.
