A pivotal moment prompted Charu Chandrasekera, a former biomedical researcher, to shift her focus from using mice for heart failure studies to developing alternatives to animal testing. Realizing the limitations of animal research, she founded the Canadian Centre for Alternatives to Animal Methods at the University of Windsor in 2017. Despite advancements like 3D bioprinted tissues using human cells, lack of funding led to the closure of her lab in 2024.
While countries like the U.K., the U.S., and the European Union have allocated resources and strategies to replace animal testing, Canada lacks a comprehensive plan for biomedical testing. This gap is significant as up to five million animals are used annually in Canadian research settings, with a substantial portion being utilized for biomedical purposes.
Advancements in technologies like organ-on-a-chip models and AI computational tools offer promising alternatives to animal testing. Milica Radisic, a professor at the University of Toronto, has developed living heart tissue that mimics real heart functions, providing a more accurate platform for testing drug effectiveness.
Regulatory bodies like Health Canada play a crucial role in determining the acceptance of alternative testing methods. While progress has been made, especially with the ban on cosmetic testing on animals, a clear roadmap for replacing animals in biomedical research is still lacking in Canada.
Despite some researchers expressing skepticism about completely phasing out animal testing due to its unique insights, the push for alternative methods is gaining momentum globally. The U.S. FDA and the U.K. have announced substantial investments in animal alternative research, whereas Canada is yet to propose funding for such transitions.
The absence of financial support for alternative methods in Canada poses a challenge for researchers like Chandrasekera and Radisic, who may consider relocating to other countries with more robust funding mechanisms. Advocates emphasize the importance of leadership and collective action to address the shortcomings in Canada’s approach to animal testing.
