Bah! I think they discovered that those stats are flawed. It is not really the accidents that are the problem ,if it was they would make old people and new drivers stop driving. I am not saying that young people are bad drivers, but in Alberta they make it harder for them to drive, through insurance rates. (I know it is a stereotypes and I am just using it as an example) If it was accident rates than they would just raise our insurance. There seems to be more to this, I think.
Rhd were not issue until their popularity increased so they are trying to regulate the market. Think about it this way. When the popularity of importing cars from the U.S. increased last year they implemented new rules to restrict the importation of newer vehicles into Canada. Really it seems in either case it comes down to money, and there is probably some type backing from Canadian Business. Big business doesn't want us going else where to buy our cars but they don't want to charge less.
That is just my take on it. I know it seems far fetched but like Nisrix said they have been talking about this since before I bought my car and nothing has come to pass.
