Attended annually by choirs of all ages, Unisong joins hundreds of like minded singers, ideally representing each province, to celebrate Canada by performing Canadian choral repertoire at a free concert at the National Arts Centre on Canada Day. In addition, each choir presents multiple smaller performances of their own individual repertoire at various venues across the city, including the Rotunda of Parliament and Rideau Park United Church.
- Free short performances by individual choirs over noon hours in the Rotunda of Parliament
- Free shared concert involving multiple choirs at Rideau Park United Church
- Free Canada Day Concert with 200-300 person choir at the National Arts Centre
