There are many of these lanes=-1 in the Canvec import in Quebec. I would assume they mean ‘Unknown’.
In my opinion we could just delete them all (at least in Quebec) since they bring no pertinent information.

Some rural areas in the USA still have one-lane roads, with occasional wider spots where one vehicle can pause to allow a vehicle going the other direction to pass by. Given how sparsely-populated some of the northern regions of Canada are, I would not be surprised to find some one-lane roads, and some extensive areas with no roads at all.
