Scientists from the University of Manitoba have penned an open letter calling on the federal government to prioritize research funding amid what they describe as an “international innovative vacuum.” Addressed to federal party leaders, the letter warns that recent US program cancellations and restrictions on scientific research could affect Canada’s own research landscape. The letter has been endorsed by more than 500 researchers across Canada. Among its recommendations, the letter urges the next government to remove the international student cap, establish a “research accelerator fund,” and increase funding for the Tri-Council agencies. “Canada must act—to protect our own scientific capacity, and to start filling the void that has been created in global science leadership and innovation,” write the authors.
