The tree-lighting activities at Yonge-Dundas Square take place this evening between 5 to 7.30 p.m. today (Saturday, November 15, 2014). They involve 52,000 LED tree and other light installations around the Downtown Yonge BIA. The event is called Iluminite. Why not. Aerial dancers will defy gravity, new costumed characters and a live band will keep things moving. Illuminite culminates with the lighting of the tree in the square. Could be good.
