If the FAA didn't cave in immediately from the EASA issuing "do not operate the airplane" then it certainly wouldn't from Transport Canada. These two do not quite carry the same weight, you know? 150M passengers enplaned and deplaned in Canada in 2017 as per https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=231002... and https://ec.europa.eu/eurostat/statistics-explained/index.php... says this number was 1043 million in the EU. According to https://www.bts.gov/newsroom/2017-traffic-data-us-airlines-a... even the USA is below that nunber with 965M.

Thank you for a detailed answer.
