There will be no mail delivery in Ottawa and the Outaouais today.

Unionized workers in the Outaouais are holding their first day of job action to back demands for a new contract.

Canadian Union of Postal Workers members in Ottawa continue job action that began on Wednesday. It's part of rotating strikes across the country by unionized workers.

Workers in Arnprior and Renfrew return to work today after a one-day strike on Wednesday.

Canada Post says there will be no mail delivery or pick-up in communities impacted by the CUPW strike action.

Also new this morning, the Canadian Union of Postal Workers is banning employees from working overtime.

CUPW says no matter what their job is at Canada Post, unionized workers will not work more than an eight-hour day and not more than a 40-hour week.

CUPW National President Mike Palecek says “this is a health and safety issue rooted in poor staffing.”
