How can one go to Canada, being a foreigner and lacking funds to attend?

I have a girlfriend from Mexico, who is living in Mexico, who is disgruntled with the education that they have there. She said she wanted to go to Canada to learn there, but doesn't necessarily has the means to attend school there. I would like to know any option that she might take to be able to attend there, maybe obtain residency there so she doesn't pay the hefty fees. I know that their are subsidized loans, but what about grants and scholarships? Any info would be great, thanks in advance.
