The Globe and Mail reports in its Tuesday edition that Restaurant Brands International is four years into a turnaround plan that has seen it invest hundreds of millions of dollars into restaurant remodels and relocations, upgrades to technology and equipment. The Globe's Susan Krashinsky writes that in Canada, Burger King holds a dollar share of just 5.3 per cent in the burger market. That puts it in the No. 4 spot, behind McDonald's, A&W and Wendy's. Its performance in the United States has similarly lagged. Burger King now has a marketing push claiming that things are starting to change: The chain rolled out a revamped version of its signature Whopper burger in the U.S. in late February, and last week, the company brought the update to Canada. The item has a different bun, and clamshell packaging to prevent it from getting squished and soggy in the bag. Canada's menu changes are also going further than the States, with new fries, chicken nuggets and onion rings. The hope is the changes drive traffic among people who have not set foot in a Burger King for a while. Average store profits slipped last year because of higher beef prices and increased contributions the U.S. owners made to the company's advertising fund.
