The smart folks a the Citizen Lab at the University of Toronto are calling for Canadian telecommunications companies to come clean about the extent to which they provide customer information and law enforcement agencies and under what circumstances.
We have seen a number of the large US internet-based companies, led by Google, provide detailed statistics about government requests for customer information. So far, no Canadian companies have followed this example so we continue to be in the dark. This is particularly important because PIPEDA has been consistently interpreted by Canadian telcos to have a massive backdoor to allow warrantless access to customer data.
