Around 500 Shaw Communications employees in Western Canada lost their jobs on Wednesday.
The Calgary-based company made the layoffs as part of a corporate restructuring to make Shaw more efficient, president Peter Bissonnette said.
There will be no impact on Shaw Media, Shaw Television or Global News, he said.
About 140 people in Calgary are being laid off, many of them managers.
There were about 50 layoffs in Edmonton.
A call centre in Saskatoon employing about 50 was also shut down. The calls handled there will now be taken by a larger call centre in Winnipeg, Bissonnette said.
About 60 people on Vancouver Island were let go, as well as 90 employees in Vancouver, including warehouse workers and management.
"It's always difficult because…most of these employees have been with us some time and have made great contributions to our company," said Bissonnette. "And unfortunately, you know, this is never pleasant."
Shaw has grown dramatically over the last two years and now employs more than 13,000 people, Bissonnette said.
