Things to do in Toronto this week include events like tree-lighting ceremonies, free concerts, and much more. With the festive season now upon us, tree lighting ceremonies are popping up everywhere in Toronto; this week, you can enjoy these events at Scarborough Town Centre and on Rosedale's Main St., where locals will gather to kick off the holidays. If you're working from the office during the week, check out Sound Break during your lunch hour, a free concert series taking place throughout the city every Thursday at noon. And for anyone looking for an immersive art experience, Enlightment — a popular light and sound show first presented in Europe — kicks off in the city this week. There's all this and so much more to do in Toronto this week, so make sure to read our previous round-ups and review our complete events calendar to help plan your outings in the city.
