Rogers handed over customer data such as names, addresses and billing information to law enforcement and government agencies in response to 97 per cent of their more than 80,000 requests last year, the company says in its third annual transparency report.

It's the first time the communications company has provided a breakdown of how many times it disclosed information and how many times it rejected requests or provided no information.

"We think this is useful information for consumers to see," said Dave Watt, chief privacy officer for Rogers, in an interview with CBC News. "Our customers' information is very important to us and we take it with a real sense of responsibility. We want them to be aware that we are making sure that the appropriate documentation is being received and when the appropriate documentation is not being received, we push back and we reject the request."

Cases are rejected when Rogers considers requests to be too broad or it disagrees that an "emergency request" without a warrant is really an emergency.

In the last three months of 2015, Rogers had 9.8 million wireless subscribers, two million internet subscribers and 1.9 million TV subscribers, according to its quarterly report.

In total, Rogers received 86,328 requests from agencies such as the RCMP, the Canada Border Services Agency, the Canada Revenue Agency, and provincial and municipal police forces in 2015. The number also included 46 requests from foreign governments and police forces.

The total number of requests was down more than 27,000, or 24 per cent, compared to 2014, when Rogers received 113,655 requests.

According to a blog post by RogersKevin on the company's official Rogers RedBoard blog, this fluctuation is "mostly due to external factors, such as the number of investigations that need to be conducted by law enforcement agencies."

But partly, it may also be because internet service providers like Rogers could much more easily hand over customer names, addresses and phone numbers to law enforcement without a warrant prior to a June 2014 Supreme Court ruling that banned the practice.

Watt said he thinks it also "probably does reflect a clearer understanding on the part of law enforcement of what is required for us to provide our customer information."

Info on 30,000 customers withheld

Rogers rejected or provided no information in just 2,457 cases or three per cent in 2015. However, some of those were "tower dump" requests involving many customers, including one involving about 30,000 customers that Rogers successfully fought in court with Telus last January.

Tower dumps are blanket requests for the information of everyone who connected to a certain wireless tower during a certain time period, typically when and where a crime is thought to have been committed.

Tower dumps are blanket requests for the information of everyone who connected to a certain wireless tower during a certain time period, typically when and where a crime is thought to have been committed. The court case involved a request from police in Peel Region for the names, numbers, addresses and banking details of everyone who connected to various cellphone towers during a series of jewelry store robberies in early 2014. An Ontario Superior Court judge agreed that in seeking irrelevant personal information, police infringed on people's charter rights to be protected against unreasonable search and seizure.

Rogers acknowledged it may have eventually provided information in some cases that were originally rejected, if police had come back with a second request that was properly documented.

While the company complied with 99.2 per cent of court orders and warrants, it was more likely to reject requests made as "emergency orders" without a warrant – allowed by law in urgent circumstances when there is a crime in progress, such as a kidnapping or child abduction.

"In some of those cases… we didn't actually feel it was an emergency situation or the request was too broad," Watt said.

In response to new transparency report guidelines from Industry Canada, Rogers added one other new category to its report this year — the number of voluntary disclosures of customer information at the request of the government organization. However, Rogers says it received no such requests this year.

Rogers also included separate categories for customer name and address checks, and requests for child sexual exploitation assistance without a warrant, but it did not report any in 2015 because of the 2014 Supreme Court ruling banning that type of disclosure. Watt said Rogers did provide assistance in child exploitation investigations in 2015, but those were covered in other categories.
