From our friends up north via Detroit:
Sir/madam,
In order to be eligible for Deemed Rehabilitation, you must have one and only one conviction in your name (DUI counts as a criminal conviction in the Canadian Criminal Code); 10 years must have passed since completion of the sentence, including probation; and the conviction must not be of a serious nature, that is would not result in a term of imprisonment of 10 years or more, should the offence had taken place in Canada.
If this describes your case you may be deemed rehabilitated and can enter Canada. We advise you to take along a recent FBI certificate and the court documentation regarding your conviction. It will be up to the officer at the Port-of-entry to decide if you can enter Canada or not.
If you are not certain that you are deemed rehabilitated , or want us to determine if you are deemed rehabilitated, submit an application for rehabilitation with the processing Fee and supporting documentation. See Rehabilitation to learn more about the process.
Note that information on how to apply for US States and Puerto Rico Police Certificates can be found at this link.
Complete applications must be submitted from the start, that is applications with the processing fee and ALL the required documentation. Applications with missing documentation will be returned to you without being processed.
For information on processing fees, please refer to Processing Fees. Press here for Detroit-specific Contact Information and Hours of Operation.
Finally Normal Processing Times for such applications is 6 months from time from the date of submission of a complete application. If there are compelling reasons for expediting your application, put in down in writing in the cover letter accompanying your application. The officer will decide if expedited service is warranted.
Do not make enquiries about an application in process within its Normal Processing time- it will not be answered.
