Canadian Prime Minister Stephen Harper called Baroness Thatcher "a giant among leaders".
The Canadian Conservative leader said: "While many in positions of power are defined by the times in which they govern, Margaret Thatcher had that rarest of abilities to herself personify and define the age in which she served.
"Indeed, with the success of her economic policies, she defined contemporary conservatism itself.
"In 2006 I met with her in London, where she provided me wise and gracious counsel, the memory of which I will forever cherish. Laureen (Mr Harper's wife) and I join all Canadians in saluting the proud life and legacy of Lady Thatcher."
