Doubt it highly - that's like 160 km/h. The official metric switch in Canada was made in 1971, but in 1984 imperial and metric were both made legal.
In the United States there's an organization called the National Motorists' Association. Somehow they managed to take down the US national speed limit of 55 mph in 1995. (88km/h)
Maybe we should start a Canadian Motorists' Association!
