Because of the principle of induced demand (https://www.vtpi.org/gentraf.pdf) it is highly unlikely that removing bike lanes will reduce the time that it takes for drivers to drive a particular route. Rather, traffic volumes will increase until the congestion returns to the same level. This means that this bill will reduce the number of people using active transportation methods like cycling, while increasing the number of people driving, without any side benefits such as reducing emissions from idling. As such, it is directly contrary to maintaining a healthy climate for Ontarians, both in terms of risks to us from climate change, and in terms of pollution related health problems.

To reduce congestion, Ontario should install more bike lanes:
"The effect of cycling on congestion
5. Cycling improvements lead to 45% less car traffic and faster
public transport (Copenhagen, Denmark)
6. Cycle highway reduces time spent in congestion by 3.8 million
hours (The Netherlands)
7. Cycle highway network reduces the need for 50,000 car
journeys daily (Ruhr area, Germany)
8. Bike share programme eases congestion during city works
(Bordeaux, France)
9. Bike share programme reduces congestion by 4% (Washington DC, America"
