The founder and CEO of AshleyMadison.com, a matchmaking site that caters to cheaters, says Ottawa is the most adulterous city in Canada.
Noel Biderman says Calgary comes in second followed by Edmonton in third.
That's based on the number of new signups the website has gotten from cities across Canada.
Biderman says it doesn't necessarily say anything bad about those cities, but it might say something about their free spirits.
The website's motto is: "Life is short, have an affair."
