TORONTO — As relations between Ottawa and Ontario grow frostier, ministers from the two governments will meet in Toronto this week to talk North American trade.

The meeting comes as the two sides can’t even agree on what was, or wasn’t, said behind closed doors about the new United States-Mexico-Canada Agreement (USMCA).

The trade talks — which until two weeks ago were among the few topics on which the two governments agreed — are now the subject of the latest flare-up between them.

On Monday, Ontario’s Trade Minister Jim Wilson accused Federal Intergovernmental Affairs Minister Dominic LeBlanc of misleading reporters about how much information Ottawa shared with Premier Doug Ford’s government during the trade talks.

Wilson will get the chance to say that to LeBlanc’s face at a meeting on Thursday.

Late last week, Ottawa ratcheted up its attacks on the Ford government, telling the Toronto Star that Ford stood “shoulder-to-shoulder” with the federal government during negotiations, only to turn his back on the deal after it was released.

“Just days before the deal was concluded, the Premier was briefed in detail in Washington, D.C., including about the modest changes to the supply management sector,” LeBlanc said in an emailed statement to iPolitics on Monday.

“His trade minister even pleaded with us to get to a deal at any cost,” LeBlanc added.

The provincial government denies both claims.

“I never said ‘at any cost,’ ” Wilson told reporters Monday.

The province also says it wasn’t briefed on the concessions made in the dairy sector, nor on a clause that gives the United States or Mexico a veto on any future trade deal between Canada and China.

Wilson said he expected to “catch up” with LeBlanc at the meeting on the changes coming to Canada’s supply-managed sectors, such as dairy and poultry.

The messaging from Ford’s government on the new deal has swung from very critical to muted. Ford himself said he could have done a better job negotiating the deal by putting “more pressure” on the White House.

Wilson has also accused Ottawa of misleading Ontario about the steel and aluminum tariffs the U.S. imposed during the trade talks. He said Ottawa had assured him that steel and aluminum tariffs would be lifted once a new deal was in place, yet they remain.

What concerns Wilson more is that the deal doesn’t stop U.S. President Donald Trump from imposing more tariffs down the road.

“He could slap tariffs on anything in the future, making NAFTA ineffective and null and void. So that, obviously, has to be dealt with,” Wilson said.

Asked how Ottawa could ever stop Trump from imposing what Canada calls “illegal” tariffs, Wilson said the federal government has to “negotiate (its) way through that.”

He repeated the response when pressed for an example of what more Ottawa could do.

The provincial NDP’s deputy leader called the premier’s flip-flops on support for Ottawa “unfair.”

“He says one thing and then does another, and this is just another example of how that happens,” deputy leader Sara Singh said.

Instead of attacking the deal, Singh said the Ford government should focus on supporting industries that will be negatively affected by it.
