A massive network outage at Rogers Communications shut down mobile and internet services across much of Canada. Millions of people found themselves offline, but the widespread impact of the outage also meant business owners couldn’t process debit card payments and many 911 services couldn’t receive incoming calls.

Today, Ben Klass, a member of the Canadian Media Concentration Research Project, explains the stranglehold that Rogers, Bell and Telus have on Canadian telecommunications and what, if anything, can be done about it.
