As you are coming to Canada under the Skilled Worker Program, if you have committed or been convicted of a criminal offence, including driving while impaired, you may be prohibited from entering Canada.
However, you may be permitted to come to Canada if you:
have applied for rehabilitation and your application has been approved; or
are able to satisfy an immigration officer that you meet the legal requirement to be deemed rehabilitated; or have obtained a temporary resident permit; or have obtained a pardon from the National Parole Board of Canada if the criminal offense was committed in Canada; or have obtained a foreign pardon recognized in Canada.
There are a number of ways to overcome a past conviction. For each of them, you must provide the documentation and information concerning the details of these convictions, including
information on the sentences you received for your convictions;
any pardons or discharges granted; and information on the laws under which you were convicted or pardoned or discharged.
Generally, you will not meet the security requirements if you have a criminal conviction. However, if a prescribed period has passed after the completion of the sentence, or commission of the offence (and during that time there have been no subsequent offences), you may be deemed to have been rehabilitated.
If you were convicted of or committed a criminal offence:
Outside Canada, you may be deemed to have been rehabilitated after 10 years have passed since you completed the sentence or since you committed the offence – subject to the offence being equivalent to an indictable offence punishable by a maximum term of 10 years imprisonment in Canada. If the offence is equivalent to a summary offence in Canada, and you were convicted of two or more such offences, that period is 5 years after the sentence was imposed or served.
Hope this help.
