Every province in Canada has moved to lower the legal limit to .05% with the exception of Quebec, where the measure is meeting resistance from local bars and restaurants.

Quebec first heard the legislation last December to allow for a civil punishment, not a criminal punishment, for any person caught driving with a BAC between .05% and .08% for just 24 hours. The license suspension would be the only penalty, and it is meant to serve as a warning. However, many feel the move will eventually lead to criminalizing driving with a BAC over .05% after an initial trial period.

Bar owners say this lower limit poses a real problem. Just one beverage, or less for many women, could be enough to put a driver over the legal limit. Restaurant lobbyist groups say this would mean a casual drinker having a few glasses of wine over dinner would not be able to driver home. This means people could start cutting out the glass of wine, and this could be detrimental to restaurant businesses that thrive on moderate alcohol sales.

Many critics also say enforcing a .05% limit would be challenging since it can be hard to detect such a low level of alcohol by observing a driver's behavior. They say the penalty may only be enforced in the rare case of an officer making a DUI stop, realizing the driver is under the legal limit but still over the .05% limit.
