I am in Alberta but for the most part, the sales should be fairly close between provinces. But I have found that even between stores in the same city, there are some items on sale that are different. In my local store, the Longanisa was in the meat section near the hot dogs.
Western Canada Costco seems to have diff selection (and sometimes prices) than we do in Eastern Canada. I am also in RH. It also varies from store to store within GTA which seems to be all about the demographics.
