Canadian Prime Minister Mark Carney is heading to Washington for his second visit this year - this time with the more modest goal of getting trade talks back on track.

Negotiations have dragged on over the summer, blowing past an August deadline set by the two leaders. But few details have been released about the discussions or the issues preventing a deal.

Canada is the only G7 country yet to reach a trade deal with Trump this year - though unlike other allies, Ottawa is not in a rush given carve-outs under the US-Canada-Mexico Free Trade Agreement.

But Tuesday's tête-à-tête comes as Trump has renewed talk of making Canada a US state, while Carney's main opposition figure has said anything short of reaching a trade deal on this trip would be considered a failure.

Canada-US Trade Minister Dominic LeBlanc said last week that progress is being made toward an agreement, and media reports suggest there may be some relief from the punishing US steel tariffs to come.

Insiders, however, have hinted at frustration over a lack of clarity from the White House on what a trade and security deal with Canada could look like.

Carney's office has billed Tuesday's meeting as a working visit focused on finding common ground on the economy and security, though no major breakthroughs are expected, White House officials told the BBC.

At the White House on Monday, Trump said only that I guess he's going to ask about tariffs.

Carney has faced domestic pressure to secure a deal with the US that would lower tariffs, especially for hard-hit sectors like steel and lumber.

In an open letter to the prime minister on Monday ahead of his Washington visit, Conservative opposition leader Pierre Poilievre urged Carney to negotiate a win.

Determining what the US wants out of the talks has been difficult to decipher.

Still, Carney has described the relationship with Trump as good and said the two routinely text.

The upcoming review of the long-standing USMCA free trade agreement will also shape the context of Carney's visit.
