Air Canada flight attendants are set to demonstrate at four major airports across Canada on Monday. The Canadian Union of Public Employees (CUPE) has designated this event as a national day of action. Picketing is scheduled to occur at 1 p.m. ET at Montreal’s Pierre Elliott Trudeau International Airport, Toronto Pearson International Airport, Vancouver International Airport, and Calgary International Airport.

CUPE aims to raise awareness about what it describes as "poverty wages" and unpaid labor that flight attendants experience while working on planes that are not in the air. The union's Air Canada component is returning to bargaining talks with the airline after its members overwhelmingly voted in favor of a strike mandate. The vote, which concluded last Tuesday, showed 99.7% support for the mandate, indicating that flight attendants could potentially strike as early as August 16 at 12:01 a.m., provided they give at least 72 hours' notice.

In addition to the picketing, other significant news includes ongoing heat warnings across Canada. A heat advisory from Environment Canada is currently in effect for southern Ontario, southern Quebec, and the four Atlantic provinces. Daytime temperatures are expected to reach as high as 35 degrees Celsius, with humidex values nearing 40 degrees Celsius in some areas. Similar heat warnings are also in place for parts of British Columbia, including Vancouver Island and the Sunshine Coast.

In legal news, the Saskatchewan Court of Appeal is anticipated to issue a ruling today regarding the province's appeal of a decision that allows a challenge to its school pronoun law. This law, enacted in 2023, mandates parental consent for children under 16 who wish to change their names or pronouns at school. The LGBTQ+ group UR Pride argues that the law inflicts irreparable harm on gender-diverse youth.

In political developments, Caroline Desrochers has become the only federal public servant elected as a Member of Parliament in the recent federal election. Desrochers, a Liberal MP for Trois-Rivières, Quebec, has a background in Global Affairs Canada, where she worked for nearly 25 years. She expressed her long-standing interest in politics, stating, "I always knew one day I would want to do that."

Lastly, scientists have released detailed images of a tectonic plate boundary off the northern coast of British Columbia. This area is believed to have the potential for significant "megathrust" earthquakes and tsunamis. The research indicates that the Queen Charlotte plate boundary is in the early stages of forming a subduction zone, which could lead to larger seismic events in the future.
