Sep 17, 2025 - Why Is Canada Building a Chain Of Dams?!



Imogen heads to northern British Columbia to check out Site C, BC Hydro’s newest (and maybe final) dam. It’s a massive project that will power around half a million homes, but it also raises big questions about the future of energy in the province.

In this episode, we take a closer look at how BC Hydro plans to meet growing electricity demand, not just through dams, but also with renewables, energy efficiency, and modernising the grid. We find out about the construction process, from site preparation to the geotechnical challenges.
Imogen also explores the big social and environmental questions that come with major infrastructure projects, including impacts on local ecosystems, communities, Indigenous lands, and cultural heritage.
