The mayors of Canada's biggest cities are pressing the federal government for immediate money to address climate change, as well as a promise of predictable transit funding down the tracks.

Making federal public transit funding permanent beyond 2027 would bring "predictability" to big cities like Ottawa that have major transit projects on their to-do lists, Jim Watson said.

Ed Holder made the pledge last month during his state of the city address, saying the move would save the city millions in fuel costs.

The Trudeau government has said investing in and developing green technology is a $26 trillion opportunity. But is it true?

"This marks a turning point for active transportation in the greater Montreal region."

While many of the instructions to cabinet come straight from the Liberal campaign platform, there are a few things that are new, or more detailed than what's been public before.

The Federation of Canadian Municipalities urged the Liberals to boost annual increases to the gas-tax fund to 3.5 per cent from two per cent, and permanently double the value of the program to just over $4 billion.

The Liberal government has committed more than $180 billion over 12 years to improving roads, bridges, public transit systems and other needed infrastructure across the country; but it has been criticized for failing to get the money out the door and shovels in the ground quickly.

"It's great to have a really big plan, but it's much better to actually have a very solid plan that's positive, that is going to happen."

In the 2015 election, the Liberals elected 50 women, and increased that by two in 2019.
