Canada is a good country, much better than Brazil. I lived there for one year and four months so I know a little bit about it. But I think that the decision of moving to another country is not easy to make. You should consider language, cultural differences, employment opportunities, being away from your family, etc. All this requires careful thoughts. So my advice is that you carefully consider all these points before making a decision. Brazil is not good in several aspects, but it is still our country, so moving away from is not an easy decision.
Currently there are more than 15,000 Brazilians living in Canada.
You may benefit from making friends with Brazilians who have already immigrated to Canada.
