My understanding is after 10 years, with no further issues, you are good to go. I got a "driving award" in 1994 and went into Canada in 2006, 2010, 2012, 2016 with no issues.
I had to get a letter from the court indicating that I had completed everything with my sentence. Mine was also over 10 years old. They still held me up at the border and searched my car, but finally let me in.
It used to be 10 years. I believe they changed it so now they can basically mess with you no matter how long it’s been if they want. I’ve crossed the border several times since my dui, and the only time they messed with me was when it had been a little less than ten years. They said you can either go back or pay a $200 “ temporary residence fee”. I paid it and we were on our way. Haven’t had any issues since. Think it’s been 23 years since my dui now.
If its 30 years old and you have had no other drama I'd wager it's unnecessary. I believe the term is "deemed rehabilitation". The timing of when you got it, and the canadian equivalent punishment at the time you got it play the largest factor in assessing the rehabiliation requirements. As of recent law changed DUI is serious criminality in Canada, basically a felony in US standards. Ultimately your at the sole discretion of the border agent at the crossing.
If I was you I'd dig up records to prove when it happened and when the sentence was completed and fines were paid and take those documents with me to present should the need arise.
I would stay away from the DUI lawyers. They're not going to tell you your good to go wish we could help but you don't need us.
What he said . No way I’d pay $1000 for them to write a letter.
Be straight forward with them at the border when they ask you questions. Answer their questions but don’t volunteer a bunch of info. Just answer what they ask. Are you going for a hunt?
