Brazilian citizen with valid green card and expired passport

[skinnerl]

Hello. I need to find out what I need to do to be able to travel to Canada. I am a brazilian citizen and I have a valid green card and driver's license, but an expired Brazilian passport. I am planning on flying to Canada in December. Do I need to renew my Brazilian passport or is the green card/ driver's license good enough. I am having a hard time coming up with the documentation needed to renew my passport. Any help would be appreciated. Thank you

You need a valid passport or a Nexus card to enter Canada.
