Canada Post has presented the union representing some 55,000 striking postal workers with a framework to reach negotiated agreements, the corporation said. A statement issued Sunday said the framework includes proposals to bring greater flexibility to Canada Post's delivery model and shows "movement on other key issues" in the labour dispute that's stretching into the holiday season.

Efforts to broker a settlement and end a strike that has effectively shut down Canada’s postal agency were suspended as the mail operator and the labor union remain far apart on critical issues.

The key issue at the heart of the Canada Post strike is the growth of gig work and other forms of precarious labour across the private delivery sector.

The union representing Canada Post workers has filed an unfair labour practice complaint with the Canada Industrial Relations Board over the layoffs of striking employees.
