This is the sorry tale of how US Customs officials decided to apply such a test – and as a result humiliated and embarrassed a Canadian woman who was on her way to run a marathon and visit friends.

The story, released today by Christin Milloy, who also alerted the world to Canada’s no-fly rule, is that of Jennifer McCreath, from Newfoundland.

Following GRS in January 2011, Ms McCreath applied for a new birth certificate from the Nova Scotia administration, secure in the knowledge that according to officials there, she should expect to wait no longer than 10 days for her new documentation.

Seven weeks later, and with no certificate in sight, Ms McCreath was forced to set off carrying only her current passport, which included a gender marker of “M”.

All went well, until Toronto Pearson international airport, where she had to go through customs before boarding her next airplane, to the United States.

A US Customs agent inspected her passport, where and directed Ms McCreath to ‘Secondary Screening’, where she was photographed and fingerprinted. A further 90 minutes elapsed before anyone else spoke to her: since other individuals were dealt with in the intervening minutes, there is some concern that this was done deliberately in order to ensure she would miss her plane.

There then followed a search of her bags and according to Ms McCreath: “They started asking me all sorts of bizarre personal questions about my sexuality.” They also asked a number of intrusive and personal questions about surgery they assumed she had had, as well as questioning her about her medication and the purpose of a highly intimate device – a dilator – that they discovered in her luggage.

This last line of questioning continued despite the fact that Ms McCreath was carrying with her a doctor’s note which, she explained, “describes (the medical device) as urgent for me to have on my person, and can’t afford to lose them in luggage and to please let me carry them on board”.

In the end, Ms McCreath was permitted to continue on her way, paying out an additional $80 for having to change flights. To add insult to injury, it subsequently transpired that had she chosen to do so, she could have obtained a temporary passport from the Canadian Passport Office in the two years prior to her surgery. However, despite several conversations and a visit to the offices of that body, she was at no time informed of this option.
