1-888-CANPASS 2-48 hrs in advance (ETA, CANPASS arrival point, tail number, full name/DOB/citizenship of each person, destination, length of stay, purpose of visit)
eAPIS 1-24 hrs in advance. Local times for crossing and arrival.
CBP of any high-value items to be declared upon return
CBP and CANPASS of any change
Note: No need to notify CANPASS of arrival if it occurs as planned; park briefly at inspection point to allow awareness for inspection. Report number is valid clearance.
>>> To U.S.:
International flight plan. Foreflight files only IFR. PC required for NavCanada web filing.

Other considerations
—————————–
No illegal substances, including expired meds
No alcohol into Canada
Expand cell phone coverage or shut off phones and data devices before entering Canada. Info in txts?
Turn off unneeded text notifications before entering Canada
Give Google Voice number for priority voice/texts and plan WiFi comm opportunities
Survival gear required over sparsely populated areas
Some Canadian airports have only approaches requiring DME and/or ADF
