Has anyone successfully moved to Canada with a less than 5 yo DUI record?

My spouse and I are hoping to move to Canada. However, he completed a DUI conviction about 2 years ago. Most material I’ve read says that he needs to pursue a Criminal Rehabilitation application, but I’ve read mixed things about being ineligible for 5 years after completing your sentence BUT it also being discretionary/on a “case by case” basis.

Has anyone had luck moving to Canada, with this similar situation?

(Please don’t scold me/us about how dangerous drinking and driving is. I know. He knows. It is one of his biggest regrets, and he is now sober because of it.)
