I believe that after CoPR, I can do an interview in an office near me or cross the border. Nowadays, they are doing some tests and some people are qualified to do the landing by phone.I've seen people say about 3-4 weeks from the day you send in your passport (assuming Brazilian nationals require a visa to Canada).
Edit: Oh, wait. You're CEC-Inland. Don't you have to appear for an interview somewhere locally?
Thank you for answering it! =)
