Canada has been cracking down on their border for the last year as well since the student worker controversy. It says: > She was planning to stay with a host family where she would carry out domestic chores in exchange for accommodation and was told she should have applied for a working visa, instead of a tourist visa She probably told the Canadian border that was her plan in Canada as well and told her she needs a work visa. Basically like a live in house keeper.
