Especially the answer to the following question:
When am I eligible to apply for rehabilitation?
You are eligible to apply for rehabilitation if:
you committed a crime outside Canada (for which you were not charged) and five years have passed since, or
you were convicted of a crime outside Canada and five years have passed since the end of your sentence.
In 1989, I was convicted of driving while impaired in the United States. I did not serve any time in prison and I have had no other convictions. Will I be allowed to enter Canada?
Based on your circumstances, it is possible an immigration officer would find you deemed rehabilitated under a system called deemed rehabilitation. Deemed rehabilitation applies to people who have one previous conviction over 10 years ago. If an immigration officer finds you deemed rehabilitated, you will probably be allowed to enter Canada as long as all other requirements are also met.
On June 3, 2003, I was convicted of driving under the influence and had my driver's licence taken away from me for three years. When am I eligible to apply for rehabilitation?
Your sentence — which includes the period your licence was suspen ded — ends on June 3, 2006. Count five years from the end date of the suspension or the date your driver's licence is reinstated. You would therefore be eligible to apply for rehabilitation on June 3, 2011.
I was convicted of a crime on December 13, 2002, and received a jail sentence of three months. When will I be eligible to apply for rehabilitation?
You can apply for rehabilitation five years after the end of your sentence . If your three-month jail sentence ended March 13, 2003, you have been eligible to apply for rehabilitation since March 13, 2008, as long as no other terms (for instance: parole, probation, etc.) were imposed on your sentence.
I have one conviction for which I was given three years of probation. Do I apply for rehabilitation after my probation is finished?
Yes, you can, but only after five years. You are not eligible for rehabilitation until five years after the end of your sentence. Since probation is included in your sentence, you can apply for rehabilitation five years after you complete your probation.
