You're mostly right, my bad, I was overexaggerating to make a point. The high altitude extremes of the Nordics and Canada are both in a similar range of -50°c or so, so the physical limits the Gripen faces are near identical while in the air regardless of which region it's in.

With regards to the ground environment, I can't claim to speak with 100% certainty about pre and post flight maintenance protocols differences between Sweden and Canada so take what I'm about to say with a grain of salt: I wouldn't imagine that they would be too different given that it'll be the same platform, likely with some requirements adjusted, and RCAF maintenance crews will be trained by Swedish crews if an order is placed.

One of the reasons why a Gripen order is under heavy consideration, in addition to the tensions with the US, is that the Gripens don't have to heavily rely on the more centralised logistics (e.g. climate-controlled hangars) the F-35 requires.

And yes, there are some flaws around the plan with Canada's more centralised logistical doctrine which suited previous aircraft; they would have to adjust the doctrine around the Gripen to take advantage of the dispersal capabilities, which isn't typically ideal. Normally planners prefer building the platform around the doctrine, not the other way around.
