A Canadian finance minister has resigned after going on a Caribbean holiday during the pandemic and seemingly trying to hide the fact by sending social media posts showing him in a sweater before a fireplace.

Ontario premier Doug Ford said he had accepted Rod Phillips’s resignation as minister hours after he returned home from a more than two-week stay on the island of St Barts despite government guidelines urging people to avoid non-essential travel.

“Travelling over the holidays was the wrong decision, and I once again offer my unreserved apology,” Mr Phillips said in a statement confirming his resignation.

In a video posted on Twitter on Christmas Eve, the sweater-wearing finance minister was shown drinking eggnog beside a fireplace with a gingerbread house and a little Christmas tree.

“I want to thank every one of you for what we are doing to protect our most vulnerable,” Mr Phillips said about Ontarians hunkered down at home because of the pandemic over the Christmas holidays.

But Mr Phillips himself had been enjoying a Caribbean vacation since December 13 on St Barts, a French island popular with the rich and famous, even as his Twitter account suggested he was in snowbound Ontario.

Opposition parties and health officials had called for Mr Phillips to be fired from Cabinet.

One party released video of a Zoom call showing Mr Phillips participating — also while wearing a sweater — with a picture of the legislature as his backdrop, but with sounds like waves heard in the background.

Arriving on Thursday at Pearson International Airport in Toronto, Mr Phillips told waiting reporters that he had made “a dumb, dumb mistake”.

“I hope people appreciate that I disappointed no one more than myself,” said Mr Phillips, who faces a mandatory 14-day quarantine for those returning from abroad.

The incident created a political problem for Mr Ford, who acknowledged on Wednesday he knew Mr Phillips was outside the country before it became public because Mr Ford said he called Mr Phillips “shortly after he arrived” in the Caribbean.

“I should have said get your backside back into Ontario and I didn’t do that,” Mr Ford said.

Ontario began a province-wide lockdown on Saturday and Mr Ford has been blaming travellers for bringing coronavirus to the province.

Canada’s national government and the Ontario government have both repeatedly asked Canadians not to travel abroad during the pandemic.

“This is a devastating blow to the government and Ford personally because, as he has admitted, he knew that Phillips was in St Bart’s and did not upbraid and order him back immediately,” said Nelson Wiseman, a political science professor at the University of Toronto. “Ford only did so once the news of Phillips’s absence became public.”

The Ford government already was being criticized for halting vaccinations over the holidays and for delaying the provincewide lockdown until the day after Christmas.

Ontario set a new daily record for cases on Thursday with 3,238.

“Ford is also suffering from the slow rollout of the vaccine, the slowest in Canada ” Prof Wiseman said.
