Celebrate Canada's 150th anniversary with this shirt displaying the official sesquicentennial logo. The logo is composed of a series of diamonds, or “celebratory gems”, arranged in the shape of the iconic maple leaf. The four diamonds at the base represent the four original provinces that formed Confederation in 1867: Ontario, Quebec, New Brunswick and Nova Scotia. Additional diamonds extend out from the base to create nine more points—in total representing the 13 provinces and territories. Happy Birthday Canada!
