TORONTO, Aug 1 (Reuters) - Canadian labour union Unifor

called on the federal government on Thursday to impose tariffs

on all Chinese-made electric vehicles (EVs), EV batteries and

other components, aligning it with some of the measures already

proposed by the United States.

In July, Canada began a public consultation process as it

weighs imposing tariffs on Chinese-made electric vehicles,

following similar moves by the United States and European Union.

The Canadian government has said it sees "a risk that

China's unfair support for the EV sector, if left unchecked,

could lead to an exponential surge of imports that will

adversely affect planned EV investments and the transformation

of Canada's automotive sector."

The public consultation process is set to end this week.

"The United States and the European Union have responded

proactively to the threat posed by unfair imports and now it's

time for Canada to do the same," Unifor, Canada's largest union

representing private-sector workers, said on Thursday.

Unifor has demanded that Ottawa impose a surtax above the

existing tariff rates of 100% on Chinese-made electric vehicles,

and a surtax of 25% on batteries, as well as tariffs on electric

motors and battery cell materials.

Even as Canada examines possible tariffs, Chinese automaker

BYD, one of the world's biggest EV manufacturers,

recently met with the Canadian government to discuss the

potential application of tariffs on EVs, and its plans to begin

selling passenger EVs in Canada.
