Interesting. First time I've heard about that. Do you know if there was any special reason why they were allowed to take the test outside?
The PDF that I received has the following notes, so apparently, this exception doesn't apply to me.
IMPORTANT NOTES:
- Please read this e-mail carefully as it contains instructions to do before, during and after the

- You must be physically present in Canada when taking the citizenship test.
