Burger King in Canada is extending its focus on letting customers customize meals with a new mobile-friendly Web site featuring a personalized interactive nutritional calculator. The new responsive site is part of an overall in-store and digital refresh designed to align the brand’s new global visual identity, with Canada the fourth market to adopt the new look, following Finland, New Zealand and India. The Add to Your Meal feature on the site enables users to swap ingredients in and out to see the nutritional value of each and adjust their personal preferences.
