Air Canada v. WestJet: Curbside Garbage Collection From Co-Founder Mark Hill's Home

What Happened

In 2003, WestJet management, centered on co-founder and VP of Strategic Planning Mark Hill, had been covertly logging into a password-protected Air Canada employee website to download proprietary flight-load and revenue data, using it to inform WestJet's own capacity and scheduling decisions. When Air Canada detected the intrusion in early 2004, it sued WestJet in the Ontario Superior Court of Justice (filed/announced in early April 2004; contemporaneous reporting places this on April 6, 2004, though a later Globe and Mail report says April 7) alleging corporate espionage, and simultaneously ran a private, physical investigation to identify and build evidence against the individual(s) responsible.

As part of that investigation, Air Canada, through its law firm Lerners LLP, hired private investigation firm IPSA International Inc. IPSA director Jasper Smith and colleague David Wiggs traveled to Mark Hill's home in Victoria, B.C. and, on March 22 and April 5, 2004, collected the contents of his garbage and recycling bins, later sorting the material away from the property; Smith's affidavit says this was done from the curbside without trespass, but Hill's own affidavit says the men walked onto his driveway to take the bins, and WestJet/Hill's countersuit alleged unlawful trespass, a dispute never resolved at trial.

Shredded and fragmentary paper recovered from the trash was sent first to a document-reconstruction firm in Ottawa and then, when that firm couldn't handle the volume, to Church Street Technology in Houston, Texas, which digitally scanned and reconstructed the shredded pages and returned images on CD. Air Canada disclosed all of this for the first time in a sworn affidavit filed with the Ontario court, made public in reporting on June 30, 2004. WestJet responded with a countersuit alleging unlawful seizure of confidential financial information (draft budgets, expense reports, compensation-committee material) and revealed that Hill, upon suspecting surveillance, had planted a fake "TOP SECRET!!!!" WestJet business plan in his own trash as bait.

The dispute also involved a separate Air Canada-hired human-surveillance operation: a contracted former RCMP staff sergeant, Robert Stenhouse, posing under the alias "Rob Stanaus" as a fake CSIS-experienced "international corporate intelligence" consultant, sat next to Hill on a commercial flight to observe him working with confidential Air Canada data.

The matter was settled on May 29, 2006, with WestJet publicly apologizing and paying a combined CAD 15.5 million (CAD 5.5M in Air Canada's costs plus a CAD 10M charitable donation).

How the Attack Worked

Air Canada suspected WestJet management (centered on co-founder and VP of Strategic Planning Mark Hill) of covertly logging into Air Canada's password-protected internal employee website ("Skybook"/employee travel portal) to pull confidential flight-load and revenue-management data, then using it to plan competing capacity. To build a case, Air Canada's outside law firm, Lerners LLP, retained private investigation firm IPSA International Inc. IPSA's Vancouver-based director of investigations, Jasper Smith, together with fellow IPSA investigator David Wiggs (both named alongside IPSA in the Ontario Superior Court case caption) and other IPSA employees, traveled to Hill's residence in Victoria, B.C. and, on March 22 and April 5, 2004, collected the contents of his garbage/recycling bins into their truck, telling an inquisitive neighbour they were Oak Bay municipal employees, and sorted the material afterward off-site.

Smith swore in his affidavit that they did not trespass onto Hill's property, took only bins already at curbside, and discarded anything that looked purely personal or irrelevant; but this is a disputed account, not a settled fact: Mark Hill's own affidavit states the men "got out of the truck and walked onto my driveway and wheeled away my recycling and garbage bins," and WestJet/Hill's countersuit formally alleged the investigators "unlawfully and surreptitiously entered onto Hill's property... and seized documents"; this factual dispute was never resolved by trial.

Recovered shredded and fragmentary paper documents were first sent to a firm in Ottawa, Forensic Document Examination Services, which found it could not handle the reconstruction and referred the material to Church Street Technology of Houston, Texas, a specialist in digitally scanning and reconstructing shredded documents; Smith personally delivered the material to Houston (April 7, 2004, per contemporaneous reporting) and received reconstructed images back on CDs.

In parallel, Air Canada also ran a physical human-surveillance operation: a contracted former RCMP staff sergeant, Robert Stenhouse (arranged by IPSA managing director Kim Marsh, a former RCMP colleague who had taught Stenhouse on an undercover course), was seated next to Hill on a March 2004 Air Canada flight to Florida. Stenhouse introduced himself under the alias "Rob Stanaus," falsely claiming six years' experience as a Canadian Security Intelligence Service (CSIS) agent and presenting himself as a specialist in "international corporate intelligence" with a firm called Eclectic Solutions Inc. (not, as previously stated here, as a fellow airline-industry traveler), in order to draw Hill into conversation and observe him working with confidential Air Canada load-factor data during the flight.

The Lure & the Tell

There was no deceptive "lure" aimed at Hill personally for the trash collection itself; it was pure physical surveillance/collection, not a social-engineering pretext against the victim directly, though the investigators reportedly told an inquisitive neighbour they were Oak Bay municipal employees collecting garbage, a minor deceptive cover story aimed at a bystander rather than Hill.

Whether the collection method itself crossed into trespass is a disputed, not settled, fact: IPSA investigator Jasper Smith's affidavit claims the bins were taken only from curbside without trespassing, while Hill's own affidavit says the men "walked onto my driveway" to wheel the bins away, and WestJet/Hill's countersuit formally alleged the investigators "unlawfully and surreptitiously entered onto Hill's property," an issue the eventual settlement never adjudicated.

The closest thing to a "tell" cuts both ways: (1) the operation was only exposed to the public and to WestJet because Air Canada itself had to disclose it in a sworn affidavit filed with the Ontario Superior Court (filed by IPSA's Jasper Smith) as part of the underlying corporate-espionage lawsuit, a first-party litigation admission, not a leak or investigative unmasking (though Hill also personally caught the investigators mid-collection, photographed them, and confronted them at the time); (2) once Mark Hill grew suspicious he was under surveillance, he planted a bogus "WestJet Business Plan" document stamped "TOP SECRET!!!!" in his own trash as bait, which Air Canada's side later took and treated as genuine intelligence, giving WestJet a concrete, provable instance of the spying for its countersuit.

Outcome

WestJet's countersuit and the public disclosure of the garbage collection and in-flight surveillance operations turned Air Canada's corporate-espionage case into a mutual-embarrassment scandal for both airlines. The dispute (Air Canada et al. v. WestJet Airlines Ltd. et al., Ontario Superior Court of Justice) proceeded through injunction hearings and dueling affidavits through 2004-2006 without ever reaching a full trial verdict on the underlying espionage claims or on the disputed trespass allegations.

On May 29, 2006, the companies issued a joint press release (filed as a U.S. SEC exhibit by Air Canada's parent, ACE Aviation Holdings) in which WestJet accepted full responsibility, apologized unreservedly to Air Canada and its CEO Robert Milton, agreed to pay CAD 5.5 million toward Air Canada's investigation/litigation costs, and made a CAD 10 million donation to Canadian children's charities in both companies' names.

Air Canada in turn withdrew its claims and all legal proceedings were terminated. No criminal charges were laid against either side over the trash collection, the shredded-document reconstruction, or the in-flight surveillance; the matter was resolved entirely as a civil settlement, leaving the curbside-vs-trespass factual dispute permanently unresolved.

Why It Matters

This is a rare case where dumpster diving as a corporate-espionage/counter-espionage technique is admitted under oath in open civil court rather than merely alleged, giving researchers an unusually well-documented, if factually contested, account of tradecraft (garbage collection method, chain of custody to a specialized document-reconstruction vendor, and the competing legal theories over curbside pickup versus driveway trespass, which the settlement left unresolved).

It also illustrates that dumpster diving is not just a low-budget attacker's tool: a Fortune-500-scale corporation (Air Canada, then emerging from bankruptcy protection) commissioned professional private investigators and a specialized forensic-reconstruction firm against a specific named executive's home, showing the technique's use in high-stakes B2B/competitive-intelligence contexts, not just against consumers or low-level targets.

The parallel in-flight operation additionally shows classic pretexting tradecraft (a fabricated identity, false CSIS credentials, and a plausible-sounding cover firm used to draw a target into an unguarded conversation) being professionally deployed by one Fortune-500 company against a named competitor executive. The case also demonstrates a defensive countermeasure, planting decoy/bait documents, used by the victim once surveillance was suspected.

Defenses

Shred sensitive documents with a cross-cut/micro-cut shredder before disposal (Air Canada's investigators were still able to reconstruct "shredded or fragmentary documents," showing basic strip shredding is not sufficient against a determined, funded adversary); do not rely on curbside placement for privacy: in most Canadian and U.S. jurisdictions, once trash is genuinely placed at the curb for collection it loses a reasonable expectation of privacy and can be lawfully taken by third parties; note, however, that whether that legal cover actually applied here is a disputed, not a resolved, fact; IPSA investigator Jasper Smith swore in his affidavit that his team took only bins already at curbside and did not trespass, but Mark Hill's own affidavit states the men "got out of the truck and walked onto my driveway and wheeled away my recycling and garbage bins to their truck," and WestJet/Hill's countersuit formally alleged the investigators "unlawfully and surreptitiously entered onto Hill's property... and seized documents"; the case settled before trial, so the curbside-vs-driveway/trespass question was never judicially decided, and it should not be read as an established legal safe harbor; executives handling competitively sensitive material should treat home trash disposal as a corporate-security surface, not just an office one: burn bags, off-site pulverization, or contracted secure destruction for sensitive personal/work overlap documents; corporate counter-intelligence awareness: Hill's own countermove (planting a fake "TOP SECRET!!!!" WestJet business plan in his trash as bait once he suspected surveillance) illustrates that once dumpster diving/surveillance is suspected, canary/decoy documents can help confirm and later prove it evidentially; organizations should have policies restricting private investigators' methods (including bans on impersonating municipal or utility workers to bystanders, which investigators here were accused of doing to a neighbor) and requiring legal sign-off, since even the commissioning company (Air Canada) ended up admitting the underlying conduct in court and issuing a costly apology.
