Hmmm... this isn't exactly recent (spring/summer/fall of 2006) - we crossed the border several times on our Alaska trip - drove up, took the ferry back from Haines to Prince Rupert, BC. We almost always had a case or two of wine and maybe a quart or two of rum on the coach. We
always declared the quantity of spirits and nobody on either side of the border had a problem, not did we pay any duty.
The key point when going into Canada is the spirits are strictly for your
personal use and you aren't going to set up a kiosk on the High Street and sell your cargo nor give/sell it to your new Canadian friends.
Only one time (clearing into BC from the ferry) did we get inspected. Showed the customs girl the spirits and the bear spray. The bear spray (purchased in Alaska) was legal in Canada because the label mentioned nothing about using it on humans - if it said you could also use it on a human attacker, it would be confiscated (sort of makes you feel safer while in Canada, eh?)
Don't worry - be happy
