Yes, the general rule is that being convicted of impaired driving you will be found criminally inadmissible to Canada as Canada views impaired driving (DUI) as a crime and anyone convicted of an offence or act abroad that is deemed a crime in Canada will be criminally inadmissible to Canada. It is how the offence is viewed in Canada that matters even if the conviction for impaired driving is not viewed as crime in the country where it occurred. This rule will apply for visitors, workers, students or anyone coming to settle in Canada. However, an individual may have some solutions. One might qualify for deemed rehabilitation of your criminal matter or one could apply to Canadian immigration for criminal rehabilitation in the case of serious criminality and if that doesn’t work then one can also apply for a Temporary Resident Permit to enter Canada at the discretion of a visa officer on the basis that the applicant has compelling reasons to enter Canada.
Deemed Rehabilitation:
If it is minor crime and 10 years have past since the completion of the sentence then you maybe deemed rehabilitated by Canadian immigration.
Criminal Rehabilitation
If it is a serious criminal conviction and five years have past since the completion of the sentence one may apply to Canadian Immigration for a declaration that they have been rehabilitated and can enter Canada.
If 5 years has not passed since the completion of the sentence then an applicant can apply for a Temporary Resident Permit which can be issued at the discretion of an immigration officer. The permit is valid for up to three years. The fee for a Temporary Resident Permit is $200.00 Cdn.
Charge(s)
If you have an outstanding criminal charge(s) that are very serious and would be treated as serious crimes in Canada then this can also preclude you from visiting, studying or immigrating to Canada. If you have prior or pending charges and or criminal convictions in the past, you may contact my office here for an assessment of the impact of your criminal history may have on you being able to enter Canada to study, work, visit or emigrate.
