So we may see some changes in the RIV document then as there are several vehicles in that list which specifically mention bumpers. I wonder how long it will take for this to be done. Reading the link it does look as if the new rules may be retroactive for vehicles that meet the US standard but not the old Canadian standard. VW R32 for instance.
i see that for a year both standards will be allowed, then it will be the new standard only and I wonder why they would not just allow both standards for ever.
