I want to move to Canada.

I am 18 years old, I work in sawmills and welding, I want to emigrate to Canada, I don't speak English or French very well, but next year I will improve both, I speak Spanish and Portuguese, can I get my Passport both Brazilian and Venezuelan (I was born in Venezuela but grew up in Brazil). What do I need to leave? I didn't finish school, I dropped out at high school, does that matter?
