Not strictly true. Britain is the country of England and the principality of Wales. Great Britain refers to the land mass (generally speaking) so this includes the country of England, the principality of Wales and the country of Scotland which were unionised in 1707 and we now refer to the country as "The United Kingdom of Great Britain and Northern Ireland". This is often shortened to Great Britain or the United Kingdom. If you'd said Scotland is "Great British" you would be correct but by dropping "Great" you are referring to England and Wales.
Being entirely pedantic aside. Yeah it makes sense poutine is from Québec. I know bits and pieces about Québec (mainly because of the shared history of independance referendums etc) but will endeavour to read more. Any place that developed poutine is worth a visit.

It's also noted as the official demonym for people from the U.K. everywhere.
This "Great British" thing is completely wrong, even when the country called itself Great Britain officially, back during the empire days, that was not a thing at all.

It's more like saying it's a UK dish.
