A Toronto Star report on the new speed humps on Leslie St. Spit references a statement from a representative of the Toronto Region Conservation Authority, who confirmed that the humps were specifically put in “…to slow speeding cyclists. The spit is a wildlife refuge not intended for high-speed cycling, she said, adding that the humps will not be altered.”

The article also quotes a Toronto Port Authority employee who said the speed humps were put in for one reason only: “To slow down spandex-clad, commando cyclists who ride too fast in groups and menace pedestrians.”
As a frequent rider on the spit, from my experience the most dangerous cyclists down there are the slower “recreational” cyclists who get on their bikes twice a year and are liable to make a u-turn in front of you without looking (it was a narrow escape).
The urban-warrior-fixie-commando types don’t go anywhere near the spit - not enough car bumpers to grab onto - so that leaves us: active cyclists (who may be guilty of wearing spandex) who are looking to get in a good training ride on a car-free roadway without leaving the city. Us who always ride the brakes and give extra room while passing families and pedestrians (and snakes as the signs request). Also, has anyone ever seen a group larger than 3 riding the spit? I have not.
Our mayor has declared an end to the War on the Car. Is this decision - which appears to have been made unilaterally and without any consultation - and the inflammatory rhetoric which supports it further evidence that there is now a War on the Bike?

"cycling’s chattering class" LOL
It's not really a new "war on the bike" but more like the continuing "war on spandex" which has been waged on multiple fronts for as long as I've been involved with organized cycling.
