MONTREAL — Being nice in Canada can sometimes feel like a full-time job.

There was that time Prime Minister Justin Trudeau cuddled with two baby pandas.

Over the weekend, Foreign Minister Chrystia Freeland welcomed a Saudi teenager at Toronto airport with a warm embrace after she had fled abusive members of her family and been granted asylum in Canada.

Now, Canadian air traffic controllers have helped burnish the country’s image as the do-gooder of the world by sending hundreds of pizzas to their American counterparts, who have been working without pay since a government shutdown began on Dec. 22.

And, yes, some were apparently garnished with Canadian bacon.

Peter Duffey, president of the Canadian Air Traffic Control Association, said the show of cheesy support began last week when employees at an air traffic control center in Edmonton, Alberta, decided to buy pizzas for their colleagues at an office in Anchorage, Alaska. Soon, dozens of other Canadian traffic control centers joined in.
