Career

Stewart is a writer, and has operated his own publishing, government relations and communications business. On November 15, 2008, Stewart was elected as mayor of Coquitlam in the British Columbia municipal elections, beating out incumbent Maxine Wilson. In 2016, Stewart revealed that he had been wearing the same suit to work events for the past fifteen months, in an effort to highlight the double standard that women in the public sphere, particularly in politics, are subject to over their appearance. He stated that while he had heard of female colleagues at both the municipal and provincial levels of government receiving negative comments about their outfits and hairstyles, particularly when they re-used outfits, he had never heard of a male politician receiving similar comments. Although his original intention was to carry on until someone noticed, he went public after fifteen months because "I was wearing the same suit to every meeting and no indication that anyone was ever going to notice."
