433 Tactical Fighter Squadron : the porcupine represents Porcupine District, Ontario. The motto translates as "Who opposes it gets hurt." In heraldic terms, the blue disc in the badge is, of course, a hurt.
What is the seasonal significance? Well, these three squadrons have been assigned to a special mission. As the RCAF explains :
"The Canadian NORAD Region (CANR) marks its 62nd year of tracking Santa Claus's yuletide journey from the North Pole with the naming of its escort pilots, maintainers and tracking crews for the high-profile assignment.
"The men and women of NORAD keep a watchful eye over the airspace of Canada and the United States 24 hours a day, and we are very proud to do so. Every year, we take on an additional, but very special responsibility – employing the same technology and systems we use to defend our two countries to track Santa's passage and escort him on his journey through North America.
"It's truly an honour to support Santa as he delivers joy and goodwill around the world."
