Despite a window air conditioner replacement program being put in place by TCH in 2019, a unit was installed in an upper-level window at the same property where a two-year-old girl died.

"One of the first priorities is to understand what exactly occurred in this situation and how did this event take place so that we can learn from it and ensure that we put procedures in place to prevent this type of thing in the future."

Toronto police said the air conditioner fell from an eighth floor apartment unit.
