Australian mining company BHP has made the largest investment in the company’s history in Saskatchewan, opening the province’s biggest potash mine. The potassium compound, known as “pink gold,” is key to growing food and is an essential part of Canada’s economy. Thirty per cent of the global supply comes from Saskatchewan alone.

The Globe’s agricultural and food policy reporter, Kate Helmore, got to see the mining project first-hand. She joins the show to talk about the development, whether it could serve as a blueprint for other major projects and what it could mean for Canada’s economic sovereignty.
