VANCOUVER, Sept 7 (Reuters) - Major telecommunication companies in Canada have formally agreed to provide support to each other and keep phone services running in case of network outages, Industry Minister Francois-Philippe Champagne said on Wednesday.

Champagne had asked telecom companies to reach such an agreement in July in the aftermath of a massive network outage at Rogers Communications Inc that impacted millions of Canadians. (Reporting by Steve Scherer in Vancouver, writing by Ismail Shakil, editing by Chris Reese)
