In 2026, AI seems to be everywhere — and some Canadians are questioning whether they want the massive buildings that power it humming away in their backyards. 

Canada has bet big on AI, and part of that push is a boom in planned or proposed AI data centres, which require vast amounts of water and energy. 

Proponents say the facilities could help secure Canada’s future as an AI leader. But the rapid pace of development has some communities hitting pause. In Ontario, Oakville voted in August to impose a one-year moratorium on data centre construction, while Mississauga is set to vote in September on a similar moratorium. Councillors there brought forward the motion after a data centre the size of three football fields was proposed.
