The Greater Toronto Area is today's target of strikes by Canada Post workers to back their union's contract demands.
Nearly 9,000 postal workers were off the job as of midnight in the latest CUPW rotating 24-hour strike.
The job action that began yesterday hit four cities -- Victoria, Edmonton, Halifax, and Windsor, Ontario.
Canada Post warns customers nationwide may experience significant delays for parcel and mail delivery in today's Toronto walkout, since the city is a key processing hub.
The union says the corporation must address the changing nature of postal work and the issues that come with handling a growing number of parcels in this era of online shopping.
