Permission to get married in Scotland

I'm engaged to a Scot and we're planning the wedding for October this year. I'm a Canadian with a working holiday visa for the UK, but we are planning to move to Canada when it expires this winter. Apparently I need a "statement in-lieu of certification of non-impediment to marriage abroad," and apparently I need to swear in front of a Canadian lawyer or notary that I am not already married. So, do I need to be in Canada to apply for this? Help! If anyone knows, or knows who would know, please let me know.

Hello MaryElizabeth, I would love to know how you got on with your certification. I am also a Canadian living in England on a Working Holiday Maker Visa and I was planning on wedding my fiance over here as well. I just wanted to know if you found out any more information about getting that certificate.

p.s. If it helps, I am almost positive that you don't need any sort of certificate to wed in Gibraltar, Spain.
