That’s nothing.
If you have ever been convicted DUI in the United States, good luck getting into to Can-Uh-Duh.
They will turn you around at the border or port of entry...
The same goes if your ride home from work had a doobie in the car when he picked you up and managed to get stopped on the way home 35 years ago.
Works BOTH ways, FRiend...
In order to enter Canada with a DUI conviction on your records, you will either need to be deemed rehabilitated or granted a temporary resident permit. A person is deemed rehabilitated if he has no criminal convictions for a minimum of 5 years after the completion of the imposed sentence.

The Canadians are some mean hombres!
They turn them back at the border, so we are stuck with them.
