To determine whether you are admissible to Canada, you must consider Canadian laws. The only way to judge if you are indeed criminally inadmissible to Canada is to first translate your conviction into the language of Canadian law.
Does the offense on your record have a counterpart in Canada? If so, then there is a chance that you are inadmissible to Canada. This concept is known as equivalence.
Offenses like DUI and reckless driving can lead to criminal inadmissibility, as they are recognized as indictable offenses in Canada. For example, if you were convicted of a DUI charge within the past ten years, you would not be able to enter Canada.
Determining equivalence can be tricky and if the correct equivalence is not found you may falsely believe that you are admissible to Canada. This could lead to being turned around at the border unexpectedly.
