Think you're OK to enter Canada with a DUI?  Think again! Even if your conviction was considered a misdemeanor under your state law, chances are the conviction is found to be more serious under the Canadian Criminal Code. Drunk driving is taken very seriously in the country and many people who have this type of conviction on their record will find that they are turned around at the border. This goes for almost every type of alcohol related offense. It is important to note that if you have a past criminal history related to alcohol of any type you are likely not going to be able to get into the country. 

Busiest USA - Canada Border Crossing

The border between the United States of America and Canada is often referred to as the International Boundary.  In terms of traffic volume, the Ambassador Bridge crossing between Detroit Michigan and Windsor Ontario is by far the most popular land border between the two nations.  In the heart of North America's industrial belt, all the commercial traffic (aka transport trucks) that go between cities such as Chicago and Cleveland, and Southern Ontario such as Toronto generally pass over this bridge.
