I saw that as well and researched it a bit. It doesn't specify but if you do a Google search for it under uber xchange toronto you can find a link but that too doesn't specify Canada. And you're right....the CSR's are a joke. They wouldn't be able to help at all.I noticed below that article is another article for Über xchange car leasing. Is that in Canada or just in the states.
I'm tempted to ask Über CSR but past experiences have made me realize I know more what's going on than they do.
