In New Brunswick for the Council of the Federation, the annual meeting of the country's premiers and territorial leaders, Ford and Saskatchewan Premier Scott Moe released a joint statement calling carbon taxes unaffordable and a risk to thousands of jobs.
"Ontario and Saskatchewan agree that the federal government should not be able to impose a carbon tax on provinces".
"That is why Ontario will be supporting Saskatchewan and intervening in the reference case Saskatchewan has launched with its Court of Appeal", the statement says.
The federal government plans to implement a carbon levy in provinces that don't have their own carbon pricing program, and possibly return the proceeds to citizens in the form of cheques.
Ford said both provinces are on "the exact same page" and Ontario will use every tool at its disposal to challenge a tax he says is bad for families and businesses.
The pair held a photo-op for reporters, but didn't comment before a bilateral meeting at the Algonquin Hotel in the scenic seaside town of St. Andrews late Wednesday night.
An independent inquiry led by a former British Columbia premier will look into Ontario's finances, newly elected Premier Doug Ford said Tuesday as he accused the former Liberal government of cooking the books and faking the deficit numbers. Ford and Moe have agreed to fight the federal government plan to impose a carbon tax.
Moe, much like his predecessor Brad Wall, has been insistent since becoming Premier in January that a carbon tax will do more harm to the economy than good.
"The parliamentary budget office has indicated that we could spend considerably less if we were to make certain changes and find efficiencies for example in bulk purchasing and other areas", said Hoskins. "We have two provinces in compliance, we have two provinces in court and we have the rest of the country not meeting the federal carbon tax backstop".
Both men left the podium outside the hotel without taking questions.
Canada's ambassador to Washington, David MacNaughton, said a meeting with the premiers Thursday explored new ways that Canada could reach out to Americans given the uncertainty over trade issues.
New Brunswick Premier Brian Gallant said provinces are willing to increase import limits, although some want to consult with the public to determine how it will be done.
In his letter, Gallant said his province also supports addressing four specific items identified by Pallister including abattoir licencing, harmonizing trucking regulations, business registration requirements, and standards for First Aid courses and kits.
He reiterated his province would remain committed to its carbon plan, while at the same time monitoring what other provinces ultimately do.
"We are open to revising ours to make sure that it is competitive, to make sure that we're still growing our economy", said Gallant.
"I think it's a waste of money for Ontario to engage in a lawsuit that we're going to lose", he said.
The provincial leaders are expected to discuss a range of other topics, including the USA trade dispute, health care, the announced pullout of Greyhound from bus routes in Western Canada, and the skirmish between Alberta and British Columbia over the Trans Mountain pipeline project.
The stance is an apparent about face for New Brunswick, which won a court battle in April against Gerald Comeau, who had fought to transport alcohol across the provincial border with Quebec.
The Supreme Court upheld the province's law that fined Comeau $240 for bringing a load of beer and liquor across the border.
"That was indeed more of a jurisdictional question and that's why the independent prosecution branch of New Brunswick chose to bring it to the Supreme Court", he said Thursday. "We have a willingness as premiers to act on this...to ensure a freer flow of beer and alcohol throughout the country".
