Apprpriate dress for ceremonial occasion

[Jock Scot]

Mike, it sounds like the OP wrote to the appropriate official organisation and received the official go-ahead to wear his kilt in the official Canadian tartan as recognised by the Canadian government. Canada's Scots make up a very large portion of the population and have contribute much to the nation's history...the first PM was Scottish-born!
There are Highland regiments in the Canadian Armed Forces. Kilted regiments from Canada have defended their nation wearing kilts!

Gaelic is a living language in parts of Canada. Scottish culture is alive and well in Canada, arguably moreso than in parts of Scotland today.

Like it or not the kilt began as a Scottish symbol (and still is, very much, first and fore-most Scotland's national dress) but has evolved to represent more than just Scotland but rather all Scots regardless of their nationality. Yes, a people's nationality and culture are two entirely different things. You're an Australian of Scottish heritage, as I understand. Australia has kilted regiments (Citizen's Brigades, if I recall correctly, and ar least five Regular Army units who were kilted for ceremony but took to the field in shorts during WWII) and Scottish-Australian organisations (military and civilian), do they not? Why the rub, sir?

I don't mean to come down so hard but goodness, man, what is the deal here?!

If I use Canada as an example. I have the greatest of respect for Canada, I have great respect for the Canadian Armed Services past and present, I have the greatest of respect for the Canadian people past and present, I have the greatest of respect for the Canadians with a Scots heritage too and I don't think there is a Scot alive that does not recognise and respect all of that fully.

However all of the above does not make any of them Scots of today, they are Canadians.
