When you want to study abroad, every financial aid is welcome. So, I suggest you to start by looking at your regular provincial financial aid program or the Millenium Foundation where you'll find financial assistance to pursue your studies either in Canada or elsewhere

Then you can have a look at specialized websites since some scholarships permit you to study wherever you want as long as you're a full-time student.

Like this site here, that addresses to aboriginal students.

Or this ons that is especially made for african students.

You may also find scholarships through companies, so I suggest you to turn to your parents employeer or yours to see if they have a program for students.

Otherwise, look at general scholarships websites but be careful, some scholarships require that you stay in Canada during all your studies or for a minimal period of time.
