Ontario Bans Invasive Experiments on Dogs and Cats—Now Advocates Want the Rest of Canada to Follow
In a landmark victory for animal welfare, Ontario has become the first province in Canada to ban invasive medical experiments on dogs and cats, along with the breeding of these companion animals for research.
The move comes after months of public outrage over a research program that subjected dogs to invasive cardiac experiments. Now, animal advocates are urging the federal government to expand those protections nationwide.
A Historic Victory for Companion Animals
Ontario passed the changes through Bill 75, amending the province’s Animals for Research Act. Once the legislation receives royal assent and takes effect, laboratories in Ontario will no longer be allowed to conduct invasive medical experiments on dogs or cats or breed them specifically for research.
The law also includes some of the toughest penalties in Canada for violations. Individuals who break the law could face fines of up to $260,000 and as much as two years in jail, while corporations could be fined up to $1 million.
Animal advocates say the legislation represents a major shift in how companion animals are viewed—not as research tools, but as sentient animals deserving of protection.
Sign the petition to encourage lawmakers to extend these protections across Canada.
Public Outrage Sparked the Change
The legislation follows widespread controversy surrounding a research program at St. Joseph’s Health Care London and its Lawson Research Institute in Ontario.
According to advocates and whistleblower accounts, dogs housed at the facility were allegedly used in cardiac experiments in which heart attacks were intentionally induced. The dogs were reportedly kept alive during the procedures for hours before being euthanized, after which their hearts were removed for research.
When details of the program became public, protests erupted outside the hospital, and growing public pressure ultimately led to the laboratory’s closure.
The controversy helped fuel calls for stronger legal protections for companion animals used in research.
More Than a Provincial Issue
Supporters of a nationwide ban argue that Ontario’s legislation should become the standard across Canada.
According to advocacy groups, millions of animals continue to be used in research throughout the country. They also point to studies suggesting that many drugs showing promise in animal testing ultimately fail during human clinical trials, prompting increased interest in developing alternative research methods.
Advocates believe investing in modern, non-animal technologies could improve both animal welfare and scientific outcomes.
Another notable feature of Ontario’s law is that laboratories will not simply be allowed to euthanize dogs and cats already housed for research. Instead, they must work with adoption and rehabilitation organizations to help eligible animals transition into new homes.
A Chance to Expand Protection Nationwide
For many animal lovers, Ontario’s legislation demonstrates that meaningful reform is possible.
Advocates now hope lawmakers across Canada will build on that momentum by adopting similar protections at the federal level, preventing invasive experiments on dogs and cats regardless of where they live.
Supporters say companion animals deserve lives as beloved family members—not lives spent inside laboratories.
