From CBC.ca:

Global Television is cutting 200 jobs across Canada as it develops new "state of the art" broadcast centres in four cities, CanWest announced on Thursday.

The company said the centres, to be located in Vancouver, Edmonton, Calgary and Toronto, will use the latest in broadcast technology. It will also mean local news programs can immediately begin the transition to high definition, CanWest MediaWorks Inc. said. 

Although CanWest is adding 50 positions as part of the process, it will lose 250 jobs, meaning a net loss of 200.
