By the last co-op term, salaries tripled in comparison to the first.
Average monthly salaries per co-op term were $2914, $4236, $5895, $7981, $9338, $10015(in CAD, includes housing stipend).
The difference could be explained by the increase in salaries and stipends to compensate for the difference in living costs between different locations. For example, San Francisco housing typically costs a student between $1,500 to $2,500 per month. In comparison, Waterloo housing costs a student approximately $700 per month.
