You still can't bring your bottle home when you go to a restaurant in Quebec, a policy that puts property rights into question and that government officials had promised to change.
The Liberal government, which had vowed to slap down the rule, was voted out and nowadays many diners believe that the law was already changed, so these days many-an-awkward moment is playing out at various eateries in the province, as waiters have to tell their customers to leave the damn bottle on the table.
A restaurant can technically lose its right to serve wine if the waiter allows one to get away, so expect a fight if you try.
The current practice also increases the chance of drunk driving, as people would likely rather finish their bottles than just leave them.
Waiters have the difficult task of policing the rule, but on the other hand they often drink the unfinished wine after the restaurant closes, so they're rewarded both ways. If you're a real smart cookie, you'll just get your wife, girlfriend or lesbian lover to put on a wine rack bra and you'll drink from your own supply.
