And another question, how strict is ArriveCAN for details of land entries? I assume if it's a different day you need to submit a new plan, but what if you change from Lansdown (Ivy Lea) to Prescott (Ogdensburg), or Buffalo to Niagara Falls?

Website says if your travel plans change, submit a new plan, but it could be pretty short notice (e.g. Google Maps might say to change crossings at the last possible moment). And they're asking exact time even for a land crossing. Does anyone have experience being off by an hour (or 2), or changing entry point, and not updating the plan?

Thanks.
