Liberal leadership: Here's where the candidates stand on key issues

As the Liberal leadership race heads into its final stretch, the four candidates jockeying to become the next prime minister continue to roll out campaign promises.

The race was triggered when Prime Minister Justin Trudeau announced in early January he'd be stepping down, after nine years in office.

Here's what the hopefuls say they'll support, and what Trudeau-era policies they would drop.

Looming over the Liberal leadership race is the existential threat posed by Trump's continual talk of annexation and his repeated threats to slap stiff tariffs on Canadian goods.

Former finance minister Chrystia Freeland, who led Canada's response to Trump during his first administration, is calling for Canada to take a more aggressive stance, including dollar-for-dollar retaliation on any tariffs and 100 per cent tariffs on Teslas, the electric vehicles made by key Trump adviser Elon Musk. Freeland has also suggested a retaliation list should be published "immediately to allow for maximum pressure."

Former central banker Mark Carney has been more reticent to speak about how he'd take on Trump, suggesting it's "not a good idea to insert yourself in the middle of a negotiation [and] give conflicting signals." He has however said he supports dollar-for-dollar retaliatory tariffs.

Former House leader Karina Gould's platform promises a "charm offensive" to stave off tariffs. She's also promised to take supply management off the table in future trade negotiations.

Former Liberal MP Frank Baylis has said Trudeau and Canada's premiers have made "mistake after mistake" dealing with Trump's threats. The Montreal-based businessman said the only way to deal with a bully like Trump is to dig in your heels and refuse to offer him anything.

In the longer term, all of the candidates have said they'd attract investment, diversify trade and ease internal trade barriers in the face of an increasingly protectionist White House.

Freeland, Carney and Gould have all said they would bail on the Trudeau government's plan to hike capital gains taxes out of concern it will hamper business investment.

The campaign so far has seen the contenders turn against the consumer carbon tax.

Not long after launching her bid, Freeland promised to scrap the Trudeau government's marquee environmental policy. 

Carney, once a vocal proponent of carbon pricing, has said he'd replace the consumer carbon tax with an incentive program that he promises will reward Canadians for making green choices.

Gould has suggested pausing the planned April 1 tax increase until a viable alternative can be put in place.
