The Ronald Reagan Foundation, which is charged with preserving the former president;s legacy, had criticised the advert for using “selective” audio and video and said it misrepresented Reagan’s address. It also said the Ontario government had not sought permission to use it.
In his post on Truth Social on Saturday, Trump said that the advert should have been pulled down earlier.
“Their Advertisement was to be taken down, IMMEDIATELY, but they let it run last night during the World Series, knowing that it was a FRAUD,” he wrote, while flying to Malaysia.
Ford had previously pledged to run the Reagan advert in every Republican-led district in the US.
Both Trump and Carney will be attending the Association of Southeast Asian Nation in Malaysia, but Trump told reporters accompanying him aboard Air Force One that he does not have any “intention” of meeting with his Canadian counterpart during the trip.
In his post, Trump also accused Canada of attempting to manipulate an upcoming US Supreme Court case which could end his entire tariff regime.
The case, to be heard by the highest US court next month, will determine whether the tariffs are constitutional.
On Thursday, Trump also lashed out, claiming that the advert was designed to “interfere” with “THE MOST IMPORTANT CASE EVER.”
The Reagan ad is not the only way that Ontario – home of the Toronto Blue Jays – is using the World Series as a platform to criticise Trump’s tariffs.
In a video posted on Friday, Ford and California Governor Gavin Newsom jokingly made bets about which team would win the series.
Both men repeatedly joked about tariffs in the video, with Ford pledging to send Newsom a can of maple syrup if the LA Dodgers win.
“The tariff might cost me a few extra bucks at the border these days, but it’ll be worth it,” he wrote.
In response, Newsom asked Ford to resume allowing American-produced alcohol to be sold in province liquor stores, and pledged to send “California’s championship-worthy wine” if the Blue Jays triumph.
They ended their exchange both declaring: “Here’s to a great World Series, and a tariff-free friendship between Ontario and California.”
