Haha don't be embarrassed, some of us Canucks are crazier than others
I am a bit more north than you, on eastern shores of Lake Superior, but I still think it's funny they call it northern Ontario here when we are clearly still in the bottom half of the province. I spent 6 years in Northern Alberta, where we would get a few weeks of -50s, that was the real North haha.
Anyway, sounds like your batch is doing well, 7 G fermenters will be fine but yeast strain can have a lot of effect on the need for a blowoff... Let us know how it turns out!
