I didn't do a survey of all of the students in my group but of the few people I chatted with I was the only OOP applicant. Maybe your cycle just happened to have the best timing for people who were flying from out of town for a weekend.
Like twenty7 mentionned, the language of instruction at UdeM and Laval is French, so someone from Montreal who would prefer study in English must apply out of province.
Regardless of how many schools are available in their home provinces, I don't think its surprising that there are some applicants who want to make a change and experience life on the other side of the country, especially in a beautiful (although expensive!) city like Vancouver
you hit the nail on the head sully22! i reckon you're from montreal as well?
