Yeah, ArriveCAN is worth it, especially if you’re not using NEXUS. It’s not like a game-changer, but it does help speed up customs. You can upload your info in advance, and that part makes it quicker. With NEXUS, tho, it’s already super fast, so it kinda depends on what you’re using regularly. Only downside I’d say is if you’re not traveling often, you might forget to fill it out ahead of time. But otherwise, no real negatives.
