Why Waterloo Is Canada's #1 Co-op Hub
The University of Waterloo's co-op program is the largest in North America, placing students in over 200 countries. For CS and Software Engineering students specifically, Waterloo co-ops are the most sought-after in the country — both by students and employers.
