Hello Jules...
I am in the middle of obtaining my British Passport...I too am a Canadian Citizen...born and bred...however both my parents (deceased) were British citizens/subjects...go to the British Embassy website in Ottawa for the link to the
UK Border Agency...and download the GUIDE UKM and the FORM UKM...it will give you all the information you need...I believe from what I have read that the British Embassy of Canada has been joined with the British Embassy of USA...therefore now resides in Washington...and it sounds to me like there is a charge of 2.90 per minute to get information over the phone! I just joined this Canuck abroad and will try to learn more and share...do share if you have learned more..
Cheers,
Patience
