I am currently trying to get british citizenship through way of "certificate of entitlement". both my parents were born and married in Scotland, however, they adopted me in Canada, shortly after their emigration.

If you have a grandfather born in the UK you will have a claim to an 'ancestral visa' where you can live and work and contribute to GDP and prove that you are not a drain on society and they will naturalise you after five years if you are a good boy of 'good character'.

I would suggest talking to the nearest british high commission. the phone rates are a little ridiculous. here's the website just in case you case you haven't had a boo.

You should be able to get a lot of info from these two sites, and/or links to the info you need. cheers.
