I don't think marijuana will ever be legalized in Canada. They tried to pass a bill legalizing it for medical purposes and it was shot down. I know my doctor would never prescribe it for medical use even if it was legalized. I wouldn't take it for medical purposes even if it was legalized. And I would hate to have it legalized because of the stench it has, some people smoke it in elevators in malls sometimes and I can't get in them, it just reeks.

People smoking it and driving it will be the cause of as many accidents as those who drink and drive. I won't be voting for legalizing it, there's enough problems with drinking without adding drugs.
And before someone says that some prescription drugs can impair your driving yes there are but there is a warning on the bottle that warns you about it. And yes, we do have idiots who disregard the warnings and drive.
