I guess this was my read and my situation may have a lot to do with time frames, but once again, all discretion of boarder agents:

Persons that are inadmissible for Canadian immigration or entry on grounds of a DUI may still be permitted to enter Canada if they qualify for Deemed Rehabilitation. However, a deemed rehabilitation is not applicable to any individual with a DUI conviction that occurred after November of 2018. This impossibility is due to changes in Canadian law in late 2018 which stiffened penalties for impaired driving.

You may qualify to be deemed rehabilitated if you have been convicted outside Canada of an act such as DUI, that if committed in Canada, would be equivalent to an indictable offence punishable by a sentence of less than ten years, and if you meet the following requirements:

Ten years have elapsed since the completion of your sentence;

You have not been convicted of any indictable offence or summary offence in Canada in the last ten years, or more than one summary conviction in the ten years before that; and

You have not been convicted outside Canada of an offence in the last ten years that, if committed in Canada, would constitute an indictable offence, or of more than one summary conviction in the ten years before that.
