The Toronto Stock Exchange is at a record high at midday, gaining 340 points, as hopes rise that a deal to end the U.S.-Iran was could be near, and oil prices fall.
The best performers are the materials and technology sectors, both up 2.2%. Energy is also higher, up 0.9%.
Telecoms, down 0.03%, is the sole decliner.
On the economics front, Statistics Canada said on Monday that the advance results for April indicate wholesale sales, excluding oil, oil products, and other hydrocarbons and excluding oilseed and grain, edged up 0.1% month over month. The increase partly reflects higher sales in the building material and supplies subsector, noted the country's statistical agency.
