Mr Trudeau gave part of his acceptance speech in French, and spoke of the links between Scotland and Canada.
He said: “Fifteen per cent of Canadians have Scottish roots, so Canadians, including me, have a strong link and affinity with Scots.”
He described the relationship between the two countries as “a relationship based on a shared past and culture, all the more so as we share a certain number of priorities and values”.
But it was the Canadian prime minister’s actually-not-that-bad attempt at a Scottish accent that had tongues wagging.
Telling an anecdote about his great-grandfather - born in Wick in 1879 - Mr Trudeau said: “Another great Scot - my grandfather, Jimmy Sinclair.
“He was born in Banffshire and as family lore had it, his father - my great-grandfather - James George Sinclair, who was a local schoolteacher was also a passionate fisherman.
“And, unfortunately, back then there were rules around who can fish in which streams.
“And about the fourth or fifth time the local constable caught him, and threatened to throw him in jail if he caught him again fishing in the laird’s stream, as family lore has it, my great grandfather says ‘But if I canna’ fish I canna’ live!’
“So he went home, unrolled his schoolhouse maps, looks at a big map of Canada, pointed to a spot on the west coast of the country, and says ‘There! British Columbia, where we can be free and no man owns the fish.’
