Bankley,

From Nova Scotia I would suggest
Joseph Howe
Cyrus Eaton
Chief Membertou

Or, alternatively
Alexander Graham Bell (though he is shared)
Donald Sutherland
Wilf Carter

As to sports. Sydney Crosby

I would not rule out Anne Murray...but according to the Olympics ads, Dartmouth's Sara MacLaughlin seems to now be from BC....figure that one out?

Here are some others

As to PEI, I would not rule out Stomp'in Tom Connore....now who can be more Canadian then Tom?
