This is Family Day Weekend, so there are a lot of family events on everywhere. The Distillery District in Toronto has the Light Festival on until March 3rd. You can see the highlights of the 2018 Festival in their gallery HERE. It "will transform the neighbourhood into one of the largest open-air galleries in North America, lighting up the long winter nights with distinctive works from local and international light artists."
Yelp has more pictures HERE. And there are some YouTube postings such as this one HERE - it doesn't have ads. If you go to TripAdvisor, there are 7,490 traveler reviews and 4,062 candid photos. That's a lot of scrolling...
There is a Winter Light Exhibition on at Ontario Place. This is surprising, given its semi-dormant status, but maybe I haven't been keeping up with its news. This is also an art installation display with information about each piece on display. There is one titled The Greenhouse - "it glows in the dark of winter, rich with greenery and blooming plants, yet simultaneously engulfed by a fire that's ablaze within".
We were at the Performing Arts Centre in St. Catharines last night for the Oscar Peterson Jazz Festival concert. The walls of the theatre light up and have a wonderful presence in the space creating an indoor light festival.
