Found this odd little anecdote in the newest issue of Macleans, in which Laureen Harper, seeking advice on family recreational activities, consults Mary Simon, head of the Inuit Tapiriit Kanatami. It's a report of an event last week at the National Gallery, a glitzy affair to kick off 2010 as the Year of the Inuit.
Over the Christmas break, the Harpers, including the PM, made a snow fort at Harrington Lake; at the event, Mrs. Harper asked the Inuit leader if she could help her make an authentic igloo. "We have lots of snow there," Mrs. Harper said. "I'm not sure it's the right kind."
Mary Simon has been a Canadian ambassador, a constitutional negotiator, a journalist, a university chancellor, and she holds three honourary doctorates, as well as the Order of Canada. I don't see any mention of igloo-building expertise on her biography (available here), but perhaps it's a hobby.
