@udo yah, u do need a visa to travel to canada. Your combo card only allow you to enter united State not Canada. Its only U.S citizen amd Green Card holder that can enter Canada without a Visa.

I am not sure you need a visa to enter Canada once you have your combo card. Apply for an Electronic Travel Authorization (eta) and that should be fine. call the Canadian consulate here or check online for more details.

mehn that Canadian Visa application is the worst though.

you need a visa. I applied but wasn’t given. I applied to uk and Ireland and got those ones.
