When federal investigators combed through activity on a government network, they alleged a longtime public servant had quietly copied more than 2,500 documents onto portable drives. That case, now headed for trial in Ottawa, took an unexpected turn: Canada’s spy agency says the alarm bell was first rung by the scientist’s own department more than two decades ago.
CSIS moves to correct the record
The Canadian Security Intelligence Service has told a court that Natural Resources Canada (NRCan) approached the agency with concerns about former departmental scientist Dennis Lu — not the other way around. In a rare step, CSIS disclosed part of one of its documents to clarify the origins of the file, CBC News reported.
During a spring pre-trial hearing, Department of Justice lawyer Sheldon Leung, speaking on behalf of CSIS, addressed how the matter began. He told the court the case started with a departmental tip, and then read from a CSIS record dated Nov. 20, 2000 detailing information from a source about a visiting delegation.
“It wasn’t CSIS flags per se, it was a [Natural Resources Canada] tip-off,” Leung said.
“On Nov. 14, 2000, a source provided the following unsolicited information regarding a visiting delegation. According to source one, Mr. Dennis Lu, research scientist at [Natural Resources’] Advanced Combustion Technology branch (ACT), had invited a visiting Chinese delegation without the knowledge of his operational manager.”
Allegations and the long gap before an internal probe
The case features a 23‑month delay between the last CSIS briefing to NRCan in February 2021 and the start of the department’s internal investigation in January 2023. CSIS did not explain the reasons for that gap in court, but new details about the delay were noted in filings cited by CBC. Following the internal review, Lu’s security clearance was revoked and the RCMP opened a criminal investigation.
Lu has been charged with breach of trust and unauthorized use of a computer. The allegations include the copying of more than 2,500 departmental files to a USB key and an external drive. None of the allegations have been proven in court.
Trial set for judge-alone proceeding
Lu is scheduled for a judge‑alone trial at the Superior Court of Justice in Ottawa in January. In pre-trial motions, the defence sought hundreds of pages of third‑party records, arguing they were relevant to the case. The court granted access to most of those materials, according to CBC’s account of the hearing.
The matter has been described in court as a foreign interference case involving China, reflecting long‑running concerns within Ottawa about attempts to improperly acquire Canadian know‑how or influence public institutions. The specific evidence in this case will be tested at trial.
Why a rare disclosure matters
CSIS seldom places its internal notes before a judge. Its decision to put part of a 2000 document on the record underscores how the agency wants the chronology understood: the initial spark came from NRCan, not intelligence surveillance of one of its own accord. That distinction could shape how accountability is allocated within government — and how departments handle security concerns shared with the spy service.
For federal workers, the case highlights the mechanics behind security screening and the flow of information between departments, CSIS and the RCMP. It also points to the challenges of moving from intelligence to evidence, and from early warnings to full-fledged internal action — especially over a span that included a nearly two‑year pause before an internal probe began.
What we know so far
- Origin of the file: CSIS says NRCan initiated contact about Lu more than 20 years ago.
- Allegations: Lu is accused of copying over 2,500 departmental documents to external media.
- Procedural path: Security clearance revoked; RCMP laid charges; judge‑alone trial slated for January.
| Event | Date |
|---|---|
| Source report of visiting delegation; CSIS note references incident | Nov. 14, 2000 |
| CSIS document produced | Nov. 20, 2000 |
| Final CSIS briefing to NRCan | Feb. 2021 |
| NRCan internal investigation begins | Jan. 2023 |
| Charges laid; trial scheduled | January (judge‑alone) |
The coming proceedings will test what investigators can prove about Lu’s conduct on the government network and how early warnings were handled inside one of Ottawa’s key science departments. For a public service under pressure to guard research and data while collaborating internationally, the stakes go well beyond a single courtroom.
