Whoa, Canada... this is why we love you so much.
MONTREAL (AP) -- Canadian air traffic controllers have bought hundreds of pizzas for their American counterparts over the past few days in what has become an industry-wide show of support during the U.S. government's partial shutdown.
Peter Duffey, the head of the Canadian Air Traffic Control Association, said Sunday the initiative began Thursday when employees at Edmonton's control center took up a collection to buy pies for controllers in Anchorage, Alaska.
Other facilities across Canada decided to join in, and the idea snowballed.
"The next thing we knew, our members were buying pizzas left, right and center for the colleagues in the U.S," Duffey said. "As it stands right now, I believe we're up to 36 facilities that have received pizza from Canada, and that number is growing by the hour."
Some 10,000 air traffic controllers in the United States have been working without pay since late December due to the ongoing government shutdown.
Duffey estimates that as of Sunday afternoon, some 300 pizzas had been received by American controllers, many of whom took to social media to express their gratitude.
Duffey said many union members had been looking for a way to show solidarity with their American colleagues.
"Air traffic control is a very stressful job," he said. "They say you have to be 100 percent right, 100 percent of the time. People just don't need to be reporting to work with the added stress of worrying about how to pay their mortgages and grocery bills on top of it."
Ron Singer, the national media manager for Nav Canada, which manages the country's civil air navigation, said Canadian and American air traffic controllers interact "on a daily basis" as they manage North American airspace.
"There's a bond there, automatically," he said.
Mark Sheehy, an air traffic controller in New Hampshire, tweeted pictures of the pizzas and his thanks for "our brothers from the north sending love and solidarity."
