It professional, looking for work and visa, don't know where to start.

I'm a Frontend Developer with 5 years of experience in the field, I don't have a BS/MS in computer science, but I have experience.

I'm currently living in Brazil and I'm looking for a place to continue working in my field in Toronto.

This question is for who knows how the market is going and can show me some sites to look for this kind of work. I don't have a visa or work permit and I need to start the process by myself. I'm going to be honest, I'm lost and don't know where to start, but I do want to leave this country and go live in Canada.
