You can do so by starting with ICBC initiatives and how unsubstantiated they were by acting on misinformation. Which was later followed by registration limitations in Quebec. In the end, I think you'll find a lot of it stemmed from money grabbing lobbyists and not by assertions of RHD vehicles being junk. Vehicles exported from Japan go through a vigorous inspection process. One doesn't have to buy a imported RHD Z32 to acquire a junk Z32. That has and can be done very easily right here with the LHD ones. Short sightedness could account for one associating RHD with junk. Or, perhaps bitterness on behalf of the LHD folk who's car values may have dropped due to the RHD imports.
