A study, authored by Zachary Spicer, Munk School of Global Affairs’ Innovation Policy Lab at University of Toronto, as well as Nathan Olmstead and Nicole Goodman, both from Brock University, found 25 percent of recent science, technology, engineering and math (STEM) graduates from the University of Waterloo, University of British Columbia and U of T were working outside Canada, mostly in the United States.

The numbers were higher for graduates of computer engineering and computer science (30 percent), engineering science (27 percent) and software engineering, where two out three graduates were working outside Canada. Nearly 44 percent of those working abroad were employed as software engineers, with Microsoft, Google, Facebook and Amazon listed as top employers.
