One thing I love about Toronto is I've never encountered even one single person doing "you're not FROM here". No one is gatekeeping the identity of being from Toronto. I felt it immediately when I moved here as an adult and it's a big reason Toronto feels like home.

On the Science Centre closure, the provincial government "claimed the roof was imminently about to collapse. We now know that the roof has not collapsed winter after winter. In fact, the roof has more integrity than the Ford government itself," says Councillor Josh Matlow.

Ford closed the science centre for no reason, is shrinking it dramatically, and gov’t doesn’t want you to know the truth about this.

Many think winter cycling is extreme.
Mostly it’s just getting dressed.
15 km in −19°C → winter gear to corporate attire.
This is my system.

John Tory couldn't get congestion pricing from Kathleen Wynne's government so the idea that Chow will manage it from some future government is... fanciful.
Councillor Jon Burnside asks if Chow would consider congestion pricing like other cities worldwide.
"It's not up to us," says Chow."Why go down that road because the premier and the provincial government have said many times, 'Don't even think about it!'"

In my brazen bike smugness I have determined that I can probably fit a 4x3 KALLAX flat pack in my cargo bike, thus saving myself the $50 delivery fee. But can *I* deliver?? Watch this space for updates!

for whatever reason, the victims of traffic violence never factor into the calculation. no urgency there. but do something that might affect a suburban lawyer who had a few drinks and then it becomes an “equity” issue

Took my sewing machine to the repair shop by cargo bike today.
Crossing guard outside the shop: "Now THAT is a setup! Is it powered? I don't drive, and I wish I had that when my kids were little!"
Shop owner: "You biked here? In this weather??? Be careful out there!"

I half-walked my bike in the worst winter bike lane I've seen yet this year, but I still made it through this section faster than the cars beside me!
