No need for the snark. I live in BC and have been both to the Okanagan & various places in Ontario. My point was that simply something happening at a certain latitude does not necessarily mean anything as you can find all sorts of climates at different latitudes. It's notable that not only is Ottawa (or whatever example you want) is at a certain latitude but that it's traditional climate is rather cold.

My point was, that simply latitude is kind of a meaningless metric as you can find different climates at all sorts of latitudes. It's more interesting that there are wineries in Ottawa because the climate in Ottawa is normally rather cold, not the latitude its at. There are lots of places with both colder & warmer climates along a similar latitude as Ottawa.
