Why do Toronto school zones have different speed limits?

I'm in whitby and tbere is the same thing by my house. 1 school is 40 and the one up the road has no speed reduction sign

In the state of Illinois all school zones speed limit is 20 MPH or 32 KMPH go above that speed limit it's a mandatory $500.00 fine

In the 1990's all School Zone are 40Km/h. 1 school zone in north Scarbough was 50Km/h. People drive with Care. Today new Generation Dont drive with Care.

Gerneration Y and Z drive without care,.

PAPPY!!!!

Miles Per Hour On Roadways Is Better

Just Add Speed Cameras
