Just as adding a filter to a cigarette doesn’t promise cancer-free smoking, pairing oil production with carbon capture doesn’t actually decarbonize the fuel. Here's Catherine McKenna on the grand bargains being discussed and why she sees CCUS as a dead end.

The courtyard in the middle of the Louvre was once a parking lot. Like so much of downtown Paris though, it's been wrested from cars and returned to human beings. I went there to see what that feels like. My new column:

The wildfire danger where homes meet forests is rising worldwide. Using new data, @rorywh.bsky.social and @cloelogan.bsky.social built a detailed map of Halifax’s fire-prone forest edge — and explain what it says about the state of the wildland urban interface in Canada.

Ford himself has acknowledged the problem, saying Highway 407 is “getting pretty busy” since tolls were lifted — even hinting the province may have to consider adding lanes to “lighten up the traffic.”

Climate policy is no longer merely about reducing emissions or averting a crisis in the future. It's now a key part of the ongoing geopolitical conflict between China and the United States — one that presents a clear risk to Canada's interests. www.nationalobserver.com/2025/09/10/o...

Ontario Premier Doug Ford made the 407 east toll-free to ease GTA gridlock. Months later, he admits it’s “getting pretty busy” and “jammed up” — proving what experts call induced demand. Experts say the real fix is better public transit and affordable transportation. @nationalobserver.com

Alberta’s grid operator has unveiled its long-awaited energy market reforms. Canadian clean energy advocates have said the plan will lead instead to higher-price gas-fired power in the future — and fewer new lower-cost wind and solar plants in the province.

The federal office tasked with ensuring the long-term health of Canadians’ pensions is accused of underestimating a key threat to those plans: climate change.

Canada is ramping up plans to export huge volumes of future liquefied natural gas production into Europe — despite forecasts of falling market demand for gas in the EU after 2030, Tim Hodgson said Wednesday.

Doug Ford says bringing employees back to the office will boost productivity, mentorship and help the downtown economy. Critics cite the environmental, mental health and equity tolls of forcing everyone to commute — but they also say the benefits are imaginary.

Robertson said the government is weighing the demand-dampening effect of its tariffs on Chinese vehicles against the need to shield auto workers from US President Donald Trump’s tariff war against Canada.  www.nationalobserver.com/2025/08/27/n...
