Toronto, Jul 9 (IANS): Queen Elizabeth, who is also the sovereign of Canada, Thursday appointed David Johnston as the new governor general of the country.

A known academic and lawyer, Johnson will take office Oct 1. An alumnus of Cambridge and Harvard universities, he is currently vice chancellor of Canada's University of Waterloo near here.

Johnson will replace Michaelle Jean who became the first black governor general of the country in 2005.

The governor general is appointed by the British monarch on the recommendation of the Canadian prime minister. He or she serves as the Queen's viceregal representative in Canada for five years.

Welcoming the new governor general, Prime Minister Stephen Harper said, "Mr. Johnston has a strong record of public service, a broad base of support and an impressive list of achievements.

"He has extensive legal expertise, a comprehensive understanding of government and a deep appreciation of the duties and tasks now before him."

The prime minister said, "David Johnston represents the best of Canada. He represents hard work, dedication, public service and humility. I am confident he will continue to embody these traits in his new role as the Crown's representative in Canada."

The appointment comes just two days after Queen Elizabeth wound up her 22nd royal visit to Canada since 1957.
