Shares in Toronto were relatively flat at midday, with gains in electronic technology stocks offsetting losses in consumer durables. Shares in Restaurant Brands International Inc. fell after the company's revenue in the third quarter missed expectations, despite stronger profit in the period.

Restaurant Brands International shares fell 1.2% to C$72.01 after the parent company of Burger King, Popeyes and Tim Hortons restaurant chains beat profit expectations but missed revenue expectations, as COVID-19 contributed to supply chain and labor challenges.
