I'm just glad Sweden now has it the way the US has it. Until around four decades ago, it used to be like the UK when it came to which side of the road to drive on.

If Canada were to change to go the UK way, it would be a commercial mistake, both for trade reasons (Canada-US/US-Canada trade) and for reasons of vehicle procurement. The only way it makes sense is if Canada wants to foolishly jumpstart a large-scale domestic car manufacturing industry when imports work just fine and are significantly cheaper.
