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.

I mean, yeah, if one is willing to leave longitude out of the equation, I guess you have a point. But any good-faith interpretation of @nsavage's original comment would assume, when reading "creeping north", they mean roughly along the same longitudinal line.
