What kind of van?
I do know for sure that CAA Quebec explicitly will not cover cargo vans or box trucks, but Ontario might be different. I think there are eight different CAA clubs in Canada, and just like AAA each one is slightly different. Look at your fine print on Eligible and Ineligible vehicles.
You may need to get RV coverage. You can also tell them, yeah, it's a cargo van, but it's your personal vehicle.
I've had AAA for more than 30 years, including the 17 years I expedited with the Sprinter. I was towed many times (oh, so many, so many many) including getting towed while loaded (both to a repair facility and to the delivery, and then to a repair facility).
