Unifor members at the CAMI Assembly and Battery Assembly plants in Ontario have ratified a new collective agreement with General Motors that achieves significant pay increases, the Canadian labor union said on Sunday.

Autoworkers at General Motors Co.'s CAMI Assembly plant in Ontario on Sunday overwhelmingly approved a new two-year contract between the company and Unifor, the union representing them, that provides pay increases and eliminates what the union called "a historic pay lag" with other Canadian GM employees.
