OTTAWA—Canada Post has bulked up its workforce as the holiday season approaches to keep up with increased mail volume.

"We've had some recent challenges in our service, but we believe we've put in place the right mechanism to ensure delivery according to our standards," said Canada Post spokesperson Anick Losier in an email.

A release from Canada Post states the company will employ 2,400 additional workers to help with the increased mail volumes during the busy season.

The National Association of Major Mail Users (NAMMU) has been keeping tabs on Canada Post's performance, as well as Canada Post pricing adjustments coming into effect January 2012. "We are optimistic that the January 2012 pricing can be overcome with mail use incentives implemented quickly in collaboration with mailers," said Kathleen Rowe, NAMMU president. "However, the real fix, according to the mail industry, needs to be in the product delivery performance, reasserting reliable, consistent mail delivery to business and consumers, as a core value. NAMMU members have been and will continue to share their delivery performance results with Canada Post. They now expect to see a very positive impact, and we have received Canada Post's assurance that they will."
