Cooling is a very variable 30% cost. (IE: Iron Mountain's underground Datacenter with a flooded reservoir in the mine gets to brag about 5% of its cost being cooling, as the most extreme low end).
Up north comes with it's own issues for Datacenters. Winter low humidity (kills cable/wire insulation), chiller freeze protection can get pretty complex to set up properly (with failures causing complete destruction of some components that will need multi-ton cranes to replace), and multi-year construction projects are harder with real winters. Sure it's all perfectly manageable engineering wise, but why bother.
There's probably easier green energy credits down south, given the current viability of solar.
