According to the Walt Disney World website, Canada Far and Wide at EPCOT will be closed beginning June 27, 2021. It is listed as closed through August 3, which is as far as the calendar currently goes.
Disney has not indicated the reason for this closure, so it may be a refurbishment or simply a mistake with the calendar.
Canada Far and Wide in Circle-Vision 360 debuted at EPCOT’s Canada Pavilion in January 2020, replacing “O Canada!” with updated footage, score, and narration. You can watch the show in our video below.
