"We leveraged our union's most powerful weapon: the right to strike," Unifor said of the tentative deal in a statement.
Unifor had sought improved wages and pensions, as well as support in the transition to electric vehicles and additional investment commitments by Ford.
The Canadian union will now turn to getting deals with General Motors (GM.N) and Chrysler parent Stellantis (STLAM.MI), whose deadlines had been extended while the Ford talks proceeded.
The UAW has said it will announce strikes against more U.S. plants on Friday if no serious progress is made in talks with automakers.
Many UAW workers are most concerned about the tiered wage structure that they say has created a yawning gap between newer and older employees, forcing some to work two jobs to make ends meet.
