Taltson hydro expansion will cost up to $3 billion, minister says – Cabin Radio

June 10, 2025

One of the NWT government’s signature infrastructure projects is now expected to cost between $2 billion and $3 billion, Caroline Wawzonek told Yellowknife city council on Monday.

Wawzonek – who is now the NWT’s minister responsible for major infrastructure builds – gave that “rough” estimate for the Taltson hydro expansion as she took questions from councillors.

While that bracket is not precise, it’s an acknowledgement that costs have escalated from the previous $1 billion-plus price tag attached to Taltson.
