Ontario’s 2026 municipal elections will be fought on familiar but sharper terrain: housing, affordability and the local infrastructure that makes growth livable. Mayors, Councillors, and municipal staff are under pressure to show real progress, not just more debate. For developers, institutions and major proponents advancing projects at the municipal level, that means one thing: if your work is visible, it will be political.

Canada’s Nuclear Renaissance, Continued
Canada unveiled its first-ever sectorwide Nuclear Energy Strategy, setting concrete build-out targets: up to 10 new domestic reactors by 2040, four new export markets by 2040, across a four-pillar plan covering domestic builds, exports, fuel/waste management, and fission/fusion innovation. The strategy stays technology-agnostic between CANDU, AP1000, and Gen IV designs, leans on existing financing tools rather than new funding (with a dedicated financing policy due next April), and frames nuclear as central to doubling Canada's grid capacity and capturing global export demand as countries move away from Russian supply chains.
