Got one in the mail last week. $120. Will cost me $100/hour in lost time to fit it. Might as well just pay it. That is what they are counting on.
In AB, the same cameras also have radar and can give you a ticket if for speeding too. Or, if you try to speed up and make the yellow light, you get 2 tickets - one for speeding, one for the red light.
We actually have about 100 of the camera boxes in Calgary, but only 20-25 cameras. They move them around every few days, so you never know if the camera is active or not.
