Tariffs trigger split between UAW and Canada's Unifor

Washington — As tensions between the United States and Canada have deepened, a longstanding historical divide has reopened between the countries’ biggest automotive unions.

The United Auto Workers, which represented workers from both countries until a 1985 split, has diverged on tariffs in recent months from Canada's Unifor. The Detroit-based union has shown tempered support for President Donald Trump’s signature policy, while the Toronto-based labor group has fiercely opposed new levies.
