The sworn statement, obtained by The Globe from court documents, reveal the first documented use of police "stingray" technology in Toronto, the country's most densely populated metropolis.

Across North America, this mobile-phone-targeting device — also known as an "IMSI catcher" — is being revealed as controversial and indiscriminate, but judges have endorsed the police legal logic in this case and others. The force last year fended off a freedom of information request from a journalist by arguing before a tribunal that any such disclosure "would quickly lessen its effectiveness" or even "jeopardize the safety of law enforcement officials operating such devices.

RCMP documents disclosed in a recent trial acknowledge that portable surveillance devices, used to target crime suspects, directly impact "innocent third parties" within range — including people dialling The machine beckons to phones suggesting it is the strongest cellphone tower in the area. Police can later try to bug the target phone.

Recent articles in The Globe and Mail have highlighted the use of this technology in Canada, where it is apparently controlled by federal police experts and lent to municipal police forces. In countries such as Germany, officials are required to disclose publicly how often they resort to IMSI catchers. In Canada, people who are not police are usually kept in the dark.

Today, the charges are heading to trial and evidence is being disclosed to the defendants. The affidavit sworn by Det. Tanabe arrived to defence counsel partly blacked out. In a February motion, criminal lawyer Craig Bottomley argued that the Crown will need to provide a lot more material about IMSI catchers — including the police operations manual — if he and his colleagues are to defend their clients.

Prosecutors replied: "The Crown will not be disclosing the operation manuals. Bids for disclosure can scuttle entire cases regardless of what the incriminating evidence is. A Montreal first-degree-murder prosecution involving gang members was recently derailed when a judge ordered the Crown to say more about IMSI catchers and related technologies than police wanted to reveal.

The RCMP appears to have pioneered police use of such devices in Canada, and it is not clear how much latitude municipal forces have to use them. The Toronto Police affidavit materials suggest a Mountie expert was brought in to operate the machine in Toronto. Tanabe sought judicial permission to use the device under a general warrant, saying in the application he was aware of no other legal power in Canada to govern the situation.

Tanabe said in the affidavit this technology would be used to identify only suspects' phones to set up subsequent eavesdropping campaigns. The MDIs themselves "will not receive voice communications and will not receive text messages or e-mails," Det. Tanabe said. Explaining he knew police in Canada must be wary of violating the Radio-Communications Act — which protects the public air waves — Det. Tanabe said the workaround was to run the machines at restricted ranges and in short bursts. Tanabe said in his sworn affidavit.

He added the machine was also programmed to shut itself down if anyone nearby tried to call The range and model of the device were withheld from the materials obtained in court.
