Rogers Communications plans to cut 300 jobs across Canada, according to MediaCaster magazine.
The layoffs will be spread out across the company's various divisions, which include cable, telecom and Internet services, TV and radio stations and magazines.
The company also owns the Toronto Blue Jays and is a partner in Maple Leaf Sports and Entertainment, which operates the Maple Leafs, Raptors and Toronto FC, among other sports franchises.
The company notified its 28,745 employees about the plan late Wednesday.
Rogers reported $12.4 billion in revenue in 2011 and is scheduled release its 2012 first-quarter earnings report April 24.
No time frame has been given for the layoffs.
