As a Canadian, I'd love to see some Canadian building represented in Lego Architecture. The CN tower and Rogers Center would be an obvious choice, but they could go with much more interesting buildings, so I'd rather see those two included in a Toronto Skyline if Lego continues making them. For non Skyline sets, the Centre Block would be amazing, as long as it includes the Library of Parliament, and the Château Frontenac in Quebec City is another iconic Canadian building they could make.
