Stephen Hawking confirmed he is coming to the Perimeter Institute for Theoretical Physics in Waterloo, Ont., next summer for a month.
Hawking, 67, based in the United Kingdom, said in a video news conference Saturday that he would arrive in Canada this summer.
Arguably the world's best-known living physicist, Hawking was to have come this summer to assume duties as a research chair at the institute.
The trip was postponed due to illness.
The institute also announced Saturday that a new wing at its facility in downtown Waterloo will be named the Stephen Hawking Centre at Perimeter Institute.
Hawking said the institute's chosen focus, quantum theory and space-time, is close to his heart.
"With a mix of excellent scientists, inspirational visitors and first-rate students recruited from around the world, I expect exciting discoveries will be made," Hawking said in a pre-recorded video message.
"Expanding the perimeter of knowledge will be the key to our future," he added.
His remarks helped launch the institute's Expanding the Perimeter campaign, a planned doubling in size of the think-tank for theoretical physics.
The Hawking wing will cost $30 million and is now under construction.
"I am strongly supportive of the institute's bold expansion plans, and its ambitious research and training programs," Hawking said.
The announcements were made as part of the institute's Quantum to Cosmos Festival, which is hosting public lectures by visiting scholars through Oct. 25.
The institute is a public-private partnership in scientific research and educational outreach and receives funding from the Canadian and Ontario governments, various universities and individual donors.
