NYC started charging a toll for cars to access downtown. I like this idea very much for the island of Montreal.

Every bridge and tunnel should have a toll, as long as the money goes to infrastructure.

Also, some good food for thought in the article.

Edit: new article with more details about the Stockholm experience: https://www.cbc.ca/amp/1.7424946

From the article: "In a city, most of the air pollution comes from people who live outside the city and choose to drive into the city. So if you live downtown, you bear the air quality penalties of the people who live outside the city," Saxe said.

Some of the reticence to congestion charges may also be due to lack of imagination, she said.

"Most people in North America have never known another way of moving around. They only know a dominant car way of doing things."

Saxe also stressed the importance the role public transportation plays in congestion pricing. It's a hand-in-glove approach: Better public transportation will get people out of their cars, as was demonstrated in Stockholm.

"There's no doubt about it," she said. "You want to do something that actually works? Congestion pricing."
