Okay, so we know that Paris has transformed itself from a car city into a biking city. Between 2015-2020 the City doubled its number of bike lanes. Then in 2021, it announced that it wanted to become a "100% cycling city" and further add to its bike network. Today, it has one of the busiest bike routes in the world and more people cycle than drive. The Globe and Mail reported, here, that last year 11.2% of trips in Paris proper were made by bike, compared to only 4.3% by car. "You would not be wrong to call it a war on the car," Marcus Gee writes. However, the result was a "victory for the city."
At the same time, we know how people will respond to this data. Lots of people will read this article and immediately say, "yeah, but that's Paris, where the average highs and lows in January are 8 and 3 degrees, respectively. It simply won't work in Toronto where our January highs and lows average 0 and -7 degrees. We have snow to contend with; they don't." And of course, they wouldn't be entirely wrong in this argument. Cycling does tend to decline in the winter months in most cities. (Note: The months of April to November in Toronto are just as warm or warmer than Paris in the winter.)
But just for fun, let's look at Oulu, Finland which has been called the "winter cycling capital of the world." Oulu has a population of around 210,000 people, an extremely low population density of approximately 150 people per km2, and January temperatures that average between -7 and -15 degrees. And yet: 40% of residents report cycling on a weekly basis, more than 40% of trips to school are by bike, 22% of all trips in the inner city are by bicycle, and this number remains at 12% throughout the winter. These Oululainens are clearly hardy people.
Here's a video comparing winter vs. summer cycling in Oulu.
I'll be the first to admit that I don't generally cycle in January and February. Partially because it's cold and partially because I don't want road salts all over my business. But the correct framing isn't that it's not possible in a city like Toronto; it's that I'm too soft. That, and we need to invest in the right infrastructure if we want more people to do it.
One of the common criticisms of bike lanes is that most people don't want to cycle in the winter. I mean, just look at Montreal's winter cycling retention ratio.
But that doesn't mean that you shouldn't invest in cycling infrastructure. Chicago, for instance, has been building out cycling infrastructure over the last few years (2020-2023) at an average rate of approximately 30 miles per year. This is double its rate from 2011-2019. And the results show.
According to recent data from Replica and the Chicago Department of Transportation (CDOT), Chicago saw the highest growth in cycling among the 10 largest cities in the US between fall 2019 and spring 2023.
Biking overall was up 119%. Crosstown trips were up 180% (bike trips that spanned across four or more neighborhoods). Trips related to shopping were up 117%. And notably, zero-car households were up 207%.
Remember, this is a city that basically has the same weather as Toronto. It gets cold in the winter. And sometimes it snows. But clearly if you build good cycling infrastructure, people will use it.

Montréal had its first snowstorm of the season this week, and if you look on X, you'll find images and videos like these😀
What's remarkable is the number of people who, at least from these tweets, continue to cycle in the winter. In fact, in the above video, there looks to be more bikes on the road than cars. Plowed lanes certainly help!
According to the city of Montréal, about 80% of the network is maintained for year-round use (717 km of its 900 km network). But I'm sure that there are a lot of people who still can't imagine anyone wanting to cycle in these conditions. So what is the actual winter usage?
Thankfully, Montréal has bike counters. 55 of them to be exact. And all of the data can be viewed, here. The busiest location is Saint Denis and Rue des Carrières. This falls within their Réseau Express Vélo (REV) network, which is a series of protected lanes intended to do what the name suggests.
The daily average for this counter is currently 4,403 riders, but the summer peak looks to be closer to 10,000. And this year, it has seen close to 1.5 million rides in total. This is a significant number. I mean, imagine 1.5 million more car trips on the road.

Looking at yesterday's data, the daily count was 1,292. If you very crudely divide this by my 10,000 summer peak estimate, you get to around 13%. And this happens to line up with what seems to be the city's generally accepted winter cycling retention ratio.

Not surprisingly, fewer people want to cycle in the winter. But the number is not nothing. If you multiple 1,292 cycling trips by 120 days (roughly December to March), that's still over 150,000 trips (I know, I didn't account for weekends). On top of this, the city's winter cycling retention rate appears to be increasing.
So just because you may not want to cycle to work in the winter, it doesn't necessarily mean that others feel the same way.
