Over 150 people became Canadian citizens in Sudbury today.   Immigration, Refugees and Citizenship Canada hosted a special citizenship ceremony at Lo-Ellen Park Secondary School.  During the ceremony those participating had to take an oath and sing O’Canada. Several ceremonies like this, take place in Sudbury every year, usually involving around a hundred people each time. CTV’s Lyndsay Aelick is covering the event and will have more details later today.
