HawaiiDan-
I don't know if you found your answer to your question:
"on my return flight from Europe, I am flying LIS-Toronto- ORD. I am not getting off in Canada... will I have to have smart phones and crap to get that silly" arrive Canada
I do not intend to set foot in any of Canada?"
But here's an excerpt for the ArriveCan Document on the Canadian Government website (the link to the site follows it):
"If transiting through Canada to another country by air
Travellers who are transiting through Canada to another country (international to international) don't need to submit their information through ArriveCAN as long as they:
are transiting through:
Vancouver International Airport
Toronto Pearson International Airport
Pierre Elliott Trudeau International Airport
Calgary International Airport
stay in the secure transit area within the airport while making their connection
A secure transit area is a specific zone that separates travellers and their baggage from other passengers and goods. If travellers are not sure whether they will need to leave the secure transit area to get to their connection flight, they must confirm with their airline prior to departure.
If you do leave the secure transit area for any reason, you will need to:
submit your mandatory public health information using ArriveCAN prior to arrival at the connecting airport.
see a CBSA officer for examination."
