Toronto cops are notoriously terrible.
Despite the incident of them being uniquely stupid that was mentioned by the OP, overall, I actually wouldn't say so.
https://globalnews.ca/news/9354642/toronto-police-homicide-clearance-rate/Toronto police are surprisingly good at solving crimes, particularly homicides. They have one of the highest homicide clearance rates (aka percentage of crimes solved) in North America - ranging from 70 to 80 percent depending on the year. Which is probably why Toronto has one of the lowest homicide rates in North America.
