If you are heading to the Canadian province of Quebec and plan to take in one of the popular tours de ville -- tours of the historic sights of lovely old Quebec City -- then know that Quebec is serious about its tour guides. Not just anyone can show you around; guides have to know their stuff!
As a matter of fact, it's the law: A Québec City region by-law mandates that local tourist guides working in the territory must obtain a valid permit each year by passing a training course, or qualifying for a certificate of equivalency recognized by two establishments that offer the special tourist guide course. This stipulation guarantees that guides who offer tours of Québec City will provide high-quality information to visitors.
See the Quebec Region site for other information about this historic part of Canada.
