To be considered rehabilitated, Canadian immigration authorities may determine that a person is no longer criminally inadmissible based on several criteria, including the following scenarios:

1. Indictable Offense (Less than 10 years): If a person has been convicted outside of Canada for an act that, if committed in Canada, would be equivalent to an indictable offense punishable by a sentence of less than ten years, they must meet these requirements:
Ten years must have passed since completing their prison term.
They must not have been convicted of any indictable or more than one summary offense in Canada during the last ten years.
They must not have been convicted outside Canada of an offense in the last ten years that, if committed in Canada, would constitute an indictable offense, or of more than one summary conviction in the preceding ten years.

2. Multiple Summary Offenses: If an individual has been convicted outside Canada of two or more acts that would be equivalent to summary offenses in Canada, they must meet these conditions:
Five years must have passed since completing their sentences.
They must not have been convicted of any indictable or more than one summary offense in Canada during the last five years.
They must not have been convicted outside Canada of an offense in the last five years that, if committed in Canada, would constitute an indictable offense, or of more than one summary conviction in the preceding five years.

3. Single Indictable Offense: If someone committed an act outside Canada that would equate to an indictable offense punishable by a sentence of less than ten years, they must meet the following:
Ten years must have elapsed since completing their sentence.
They must not have been convicted of any indictable or more than one summary offense in Canada during the last ten years.
They must not have been convicted outside Canada of an offense in the last ten years that, if committed in Canada, would be an indictable offense, or of more than one summary conviction in the last ten years.

Individuals do not need to apply to be deemed rehabilitated; however, anyone with a criminal record planning to travel to Canada should verify their rehabilitated status to avoid complications at the border. If an immigration officer finds that a person has not been deemed rehabilitated, entry to Canada could be denied due to criminal inadmissibility.

It’s advisable for anyone with a criminal record to consult with the Canadian consulate or a Canadian immigration law firm to discuss potential inadmissibility issues. This precaution helps ensure that they do not travel to Canada only to face refusal of entry or other enforcement actions.
