Three Sisters usually gets covered as one giant, controversial project. Up to 7,000 homes. 15,000 new residents. A doubling of Canmore’s population. That framing makes for dramatic headlines. But it hides the one detail that actually matters for business decisions: this isn’t happening all at once. The pacing itself is the strategy.

Why the Phasing Matters More Than the Total

The Three Sisters Village Area Structure Plan releases land in phases on purpose. This prevents the market from flooding. Phase 1 covers roughly 700 to 1,075 residential units on 29 hectares, and construction is underway now. A density bonus system lets unused density shift from one phase to another. Smith Creek, the second major component, can’t begin until crews finish a wildlife underpass beneath the Trans-Canada Highway. That ties its timeline to infrastructure, not demand.

Watch the Underpass, Not the Announcements

That underpass is the single best thing to track if you want to time an investment here. It’s a hard, physical, publicly-tracked construction milestone. It gates the release of the largest remaining land event in Canmore’s history. Treat its completion date like a regulatory filing deadline. Land use applications and commercial pre-leasing activity tend to accelerate sharply in the months before a milestone like this clears.

Read the Signal Hidden in Phase 1’s Pace

There’s a quieter signal too. Because density can shift between phases up to a 5,000-unit cap, how fast Phase 1 sells tells you how aggressively the developer plans to pursue later phases. A quick sell-out signals Phase 2 applications will land sooner than official documents suggest.

Underwrite Three Sisters phase by phase, not as one single risk. The commercial and hotel district written into Phase 1 offers the nearest-term opportunity for retail and hospitality operators. The Gateway commercial node already proves that anchor tenants want in early, a pattern worth watching as later phases mature.
