Unifor has reached tentative collective agreements with CN Rail, averting strike action. The four tentative collective agreements cover Local 100 and Council 4000 members across the country. Unifor's two national bargaining committees opened negotiations with CN in October 2022.

Unifor Local 100 represents skilled trades in mechanical shops and Unifor Council 4000 represents intermodal, clerical, mechanics and excavator operators. Unifor is the largest union at CN. Details of the collective agreement will not be releases until after ratification.

Ratification votes will be held in the near future.
