Here in Montreal the local competitor Communauto is doing great, but with both Zipcar and car2go usage models in the same subscription, and cheaper than any car-based alternative including both of those as well as taxis and Uber.

"Local" is a bit misleading - they're indeed based here, but they also serve Quebec City, Ottawa, Toronto, Halifax, and over in Europe, Paris. (Service details vary by location outside the province of Quebec.)

Yeah, but uber is running at a loss... Sooner or later they will increase the cost.

But I doubt that they will come back....
