Much of the cardboard and paper goods strewn about our homes are sold by a single private company, with its name, Uline, stamped on the bottom.
Many may not know that a multibillion-dollar fortune made on those ubiquitous products fuels far-right candidates across the country.

That Cardboard Box in Your Home Is Fueling Election Denial
A previously unreported boom in profits for the shipping supply giant Uline has provided the funds for a deeply conservative Midwestern family to bankroll anti-democracy causes around the country.

Remember when summer used to be carefree and fun, not filled with apocalyptic challenges from wildfires to suffocating heat? Tackling #ClimateChange requires mitigation and adaptation, not just eco-anxiety, by @picardonhealth.bsky.social www.theglobeandmail.com/opinion/arti... @theglobeandmail.com
Opinion: Rescuing summer holidays from the clutches of climate change

We’re setting the record straight on dedicated lanes. Red lanes on Dufferin and Bathurst will make our travel faster, safer, and more accessible. They will also help cut congestion and reduce pollution.

Agree! Need the Government of Ontario to step up and properly fund @tdsb.on.ca and other school boards, and not threaten to take their land or governance
This article is from 2008. Together, we fought hard to save Toronto’s school pools. Today, they’re threatened with closure once again. It’s time for life-saving aquatic programming, outdoor education and special needs programs to finally be supported by the province
