I am brazilian, living in the U.S. with a F1 Visa, and If i decide to visit Canada, do I need a Visa? Since I am not american, and if I was in Brazil, I know they require Visa to go to Canada, if you depart from Brazil...Do I need Visa departing from the U.S.? Thank you

No, you can not come to Canada without a Visa.

Only US citizens may enter Canada without a Visa, and since you are not a US citizen, but rather a citizen of Brazil, you will need a Visa.

Since, citizens of Brazil require Visas.
