Many countries test people before they board an airplane in the first place, and some require tests upon landing, Dr. Marek Smieja, MHL scientific director and co-author of the study, told CTV News.

They literally relaxed the rules and requirements to entry to Canada for foreigners while making the rules more strict for Canadians.

Usually when going to other countries they won't even check you in to board the plane without a covid test done in the last 48 hours which usually costs hundreds of dollars, but not if someone is going to Canada! That person will get a test done free of charge when he lands here, and its get paid for by Canadian tax payer money. Sounds really fair huh?
