Put another way, Ford wants to spend more on removing bike lanes in Toronto ($48M) than he's spent protecting all of Ontario's businesses from an international trade war.
Ontario deserves serious leadership, that follows through on promises, and actually puts people before profits.

And with gas so cheap!
Trump officially rolled back fuel efficiency standards today. The new target for 2031 is about 34.5 miles per gallon, down from 50.4. That means more gas burned, more pollution, and more money out of drivers’ pockets. So much for making things affordable.

They tried their best to make the idea of having more things we want nearby, more options and choices in our cities and neighborhoods, seem like a conspiracy. But never forget what the REAL urban conspiracy has been — moving everything further away and making us car dependent. #1HourCityConspiracy

The Trump administration wants to cull people with disabilities from the workforce.
Requests for disability accommodations are not special privileges. They are required for people with disabilities to be able to work, and they should not be treated carelessly or maliciously.

We often treat exercise as productive punishment.

Two extraordinary charts from today’s PISA test results:
1) School test scores continue to collapse internationally, underscoring how this is no longer a Covid effect but sustained decline.
Those falls in reading and maths are equivalent to about two years of lost schooling.
