Government of Canada Invests Over $9 Million to Enable Made-in-Canada Lithium Battery Supply Chain in British Columbia
"The $4,937,500 investment to Saltworks will be used to accelerate the concentration and conversion of Canadian lithium brine into lithium battery precursors using two novel technologies developed and tested by Saltworks. This project could accelerate access to lithium resources and reduce investment risk in Canada’s brine-to-battery lithium industry."

There's a lot of protest going on in Saskatchewan right now. OEMs, the Minister of Energy and Justin Trudeau are calling up Paulo every day demanding Prairie go into production sooner and have threatened to throw more money at him.
