The telecommunications giant says the move follows concerns from subscribers and a landmark Supreme Court of Canada ruling last month.
Rogers received almost 175,000 requests for customer information from government and police agencies last year.
The company says it responded to name and address requests — which totalled 87,856 last year — so police would not issue a warrant to the wrong person.
Rogers says the new policy of requiring a warrant even for such basic requests will be better for its customers, and that law enforcement will still be able to protect the public.
It adds that police would not need a warrant to get basic subscriber information in life-threatening emergencies.
