Layover in YVR from USA with DUI

I’m a US citizen with a DUI 9 years ago. I’m traveling to Hong Kong with a layover at YVR. Do you think I’d have any issues getting through the airport and on to my connecting flight?

I’ll be going from LAX to YVR and YVR to HKG through Air Canada. I’ll also be landing at Terminal M at YVR and flying out of the same terminal.

UPDATE on 09/06/2024: I was able to get ahold of a Canadian border patrol agent who let me know I’ll need a TRP (temporary resident permit) even to transit. I also learned that YVR has a sterile transit area, and that you use a kiosk to scan your passport, and not an agent. Due to conflicting information, and not wanting to risk my travel plans, I decided to bite the bullet, cancel my flight through Canada, and rebook it to avoid Canada. Expensive, but in the overall scheme of things, the time, and additional money that I would have had to spend if I wasn’t let through wasn’t worth it for me to leave up to chance.
