The coop of waterloo is mainly, or almost only for biostatistics. And the institutions for your coop terms are hospital, research institute or something like this. If you want to get coop chance in finance area, Master of Quantitative Finance is the best choice. But it's really hard to apply, a lot of the students in that program have already got a PhD degree or a Master degree.
Anyway, waterloo is quite strong in statistics, so this program is quite a good choice. Welcome!
