In another twist of the tale, it was the Canadians that refused her entry because of her working in the US (?) so she had to re enter the USA and it was there she as detained. Why would the Canadians have a problem with her, unless she had a tourist only visa for Canada, told them she had been working in the US and clearly had a tourist only visa for there and consequently the Canadians thought she would end up working illegally in Canada so refused her entry.
