In April 2009, Robertson was recognized for his interest in aviation and the Canadian military by being named Honorary Colonel of 424 Transport and Rescue Squadron of the Canadian Forces. Following the signing, HCol Robertson said that the investiture was "the most incredible honour" he has received. "I have always been thoroughly blown away by the incredible work of our military," he said. "It's a day I thought I would never see come. When I got the letter from the Defence Minister, I was, like, ‘This is real; I am actually going to be an honorary colonel!’" Robertson held the position until March 2012, noting that, although he had not been able to be around as much as he would have liked, the Squadron felt like family to him.
