ONE is a bombastic 70-year-old billionaire who has banned refugees, scrapped a free-trade agreement and promised to “drain the swamp”. The other is a 45-year-old feminist from a political dynasty who has welcomed immigrants and pledged to fight climate change.

In their first face-to-face meeting since President Trump took office, Canadian Prime Minister Justin Trudeau will have to bite his tongue on certain issues in order to preserve Canada’s trading relationship with the US which is worth an estimated CA$2 billion a day.

The two leaders will meet a full day of talks in Washington on Monday, including a round table with female business executives from the US and Canada, some of whom were chosen by Mr Trump’s daughter Ivanka.

They’re also expected to talk trade, which is particularly critical for Canada given the US is their biggest trading partner and a critical partner of the North American Free Trade Agreement (NAFTA), along with Mexico.

President Trump has previously said he would rip-up the 1994 deal which accounts for more than $1 trillion worth of trade between the three countries. Any changes could be particularly worrying for Canada which relies on their southern neighbour for 80 per cent of their trade, the Financial Post reports. Just 18 per cent of US exports go to Canada.

Ahead of the meeting, Prime Minister Trudeau was urged to strike a balance between not wanting to “be a Malcolm” and invoke Trump’s wrath, while maintaining support among his core liberal voters.

It comes after Trump’s team was forced to pull his official inauguration poster after a typo in the quote, in the latest gaffe for his administration team.

Canadian and US officials said the leaders would announce a United States Canada Council for the Advancement of Women Business Leaders-Female Entrepreneurs during the meeting.

University of Toronto political expert Nelson Weisman said the choice of subject matter was a “smart thing” because it kept the emphasis off trade.

“It takes attention off of NAFTA. And from Trump’s point of view, it contributes to softening Trump’s image, and he’s got a problem with women,” he said.

Mr Trudeau has previously painted himself as a champion of female issues, calling himself a feminist, created a cabinet of 50 per cent women and welcomed 40,000 Syrian refugees.

During the campaign, President Trump made headlines for calling Hillary Clinton a “nasty woman” while a leaked video showed him talking about grabbing women “by the pussy” years earlier.

Ahead of the visit, Mr Trudeau said he would discuss “the fact that millions of good jobs on both sides of our border depend on smooth flow of goods and services across that border” as well as things the pair disagree on.

Over the weekend, Canada’s Toronto Star warned Trudeau not to emulate Malcolm Turnbull or UK Prime Minister Theresa may.

“Don’t be a Theresa. Don’t be a Malcolm,” the editorial board wrote.

“As Justin Trudeau heads to Washington on Monday for his much-ballyhooed first face-to-face meeting with Donald Trump, the prime minister has two clear examples of what not to do.”

“The trick for Prime Minister Trudeau will be to avoid both these pitfalls.

“To be friendly, but not too friendly, at least in public.

“To clearly assert Canadian values, but not in a way that will be seen as a direct rebuke to Trump, especially as his guest in his own house.”
