Hi Mike
Yes, they are of the Military Police/Security Officer Trade. Not what you may think a Commercial Airline "Air Marshal" does but rather Canadian VIP Aircraft/Airport Security particularly when the VIP is abroad.
"...The Canadian Forces Air Marshal Detail (CFAMD) conducted twenty-nine very important person aircraft security missions in 2010, resulting in MP personnel travelling over 208 calendar days to 25 countries. The CFAMD provided close security support to 412, 429 and 437 Transport Squadrons while transporting Her Majesty Queen Elizabeth II and His Royal Highness Prince Philip; Her and His Excellency, the Governor Generals of Canada; the Prime Minister of Canada and various Heads of State..."

Hi Bill
It is my understanding that these cannot be worn on a uniform. A memento or souvenir that can be worn on personal civilian attire.
