A US-based Canadian citizen who came to handle an installation for us last year was given a prolonged grilling by CBSA in St John's. They also demanded to know where her visa was, and the precise nature of the work she was to perform in her home and native land. Seems almost like a trend.
I'm English. The most any UK immigration officer has ever said to me is, "Welcome back".
