Could it be that a lot of these young, bright folks would just rather live in the US, and getting a valuable degree enabled them to do what they've wanted to do for some time?
UWaterloo is one of the most rigorous schools in Canada, particularly in CS, math and science subjects. A six-figure job in America is pretty much the only light at the end of the tunnel for them.
Sometimes Waterloo kids take friendly jabs at the other school in the city, Wilfried Laurier. But the image of the two schools couldn't be more different. WLU is the party school that grades on a curve. Waterloo is much harsher academically, and the jokes and memes are usually focused on CS/Math kids having no friends, playing DoTA and waiting for their summer placements in SV.
I would be curious to see the number of students with immigrants parents; maybe they tried to go to the US but couldn't due to stricter policies. Now the kid can.
That doesn't explain why the rate is that high. It only explains why those students move to the US and I personally would rather stay in Canada if I were born in Canada.
