Back to Potash Facilities


Our Colonsay potash site, located near Saskatoon, SK. has been in care and maintenance mode since it was indefinitely idled in August 2019 due to challenging market conditions. Work is now underway to re-start the facility, with production expected to resume this summer.

Production is expected to resume at Colonsay summer 2021, which will offset a portion of the production lost by early closure of K1 and K2. To accomplish a safe return-to-production, we have temporarily recalled hourly employees, developed contract staff roles, and brought additional support from Esterhazy and other Mosaic locations in Saskatchewan.

The current focus for Colonsay is on the near-term four-month sprint to resume production and meet promised 2021 customer orders through to the end of the year.
