    I live near Montréal (in Longueuil) and commute by bike and do many house calls by bike (I work in a CLSC). I’m lucky to have nice bike lanes around. I hear that in Montreal bike lanes are crowded and used by high speed cyclers and my cousins prefer to bike to work on well-known calm streets. I’m sure the fact that many people in Montreal don’t have a private parking space is as much a shove toward cycling (or public transport) as the bike lanes are. The hassle of shovelling snow out of a new space to park along the street when arriving home after work (because someone is parked in the one you shovelled yesterday) just cuts down on the pleasure of owning a car.

    As a cyclist and a doctor I empirically agree, but I would like to see some bibliography to back with studies what is stated here. Thank you!

    Your article is truth, accurate and honest. Ive been living in Copenhagen for 15 years, was born and grew up in Rio de Janeiro. My experience is that life is healthier here in Cph due to the urban planning particularly the bicycle lanes infrastructure, among others, compared to Rio despite its nature and good weather.. but I just think there is a clash in your article when you start with “Over drinks..” to talk about health care :-/ ;-) :-)

    Does this factor in the health care costs from bicycle accidents? Recent reports in Toronto indicate something like 10 bicycle accidents a day. What is needed is separated bike lanes and not bike lanes adjacent to any stopped or parked cars – dooring is significant and lands many people in hospital and often ends their cycling.

    Dear Danny. Fantastic article which clearly and succinctly makes the strong argument as to what and why our city needs to do to step up to better support the health of our citizens and become the international city it should be. Would love to meet with you to discuss further how to make this happen. Patricia Houston Vice Dean MD Program U of T

    Thumbs up for this write up…I researched a similar topic as an undergraduate (though among high school kids) and I reached similar conclusions to yours, namely that the potential benefits accruing from physical activity are enormous and that active commuting is a very cheap and almost non-cumbersome way to get the recommended daily dose of exercise. Would love to see this message blared from every bulletin, billboard and electronic screen.

    you’re sure right.

    What an interesting perspective! I agree with you that most challenges facing our health care system can be overcome by implementing small changes in our lifestyles because as you implied, our health is ultimately in our hands. And the best way to allow people to lead healthier lifestyles is to provide them with the necessary resources to do so. Thanks for sharing your unique take on this topic!
