#612 Blair Road Project ...update

As of mid-November 2026 the registry still shows the assessment as in progress and contains no Notice of Determination on whether the work is likely to cause significant adverse environmental effects.[5]

Big Science, Thin Paper Trail: The TerraCanada Lab on Blair Road

Updated 14 November 2026 · Civic accountability · Ottawa–Rideau–Rock cliffe

The short version: A roughly $1.05-billion federal science facility is under construction at the corner of Montreal Road and Blair Road. It will house laboratories for Natural Resources Canada and the Canadian Nuclear Safety Commission, including a Class II nuclear facility. NCC design approvals have advanced, but the federal Impact Assessment Registry still lists the Phase 2 assessment as “in progress” with no published determination, and key details on servicing, power, transportation, and the nuclear licensing process remain difficult to find in one place.

Current public status (mid-November 2026)

• NCC design: 100% schematic approved September 2025; 100% developed design approved (October 2026 board materials).
• Construction: PSPC reports major construction began after July 2026 groundbreaking; substantial completion targeted for 2031.
• Impact Assessment: Phase 2 (ref. 89958) still “in progress”; public comments closed 1 April 2026; no Notice of Determination posted.
• Nuclear: PSPC project page lists a Class II nuclear facility as part of the building. Separate CNSC licensing applies.
• Parking: ~196 spaces for ~490 staff (~0.4 spaces per employee).

What is being built

The TerraCanada Science and Innovation Hub is one of two new federal science facilities that Public Services and Procurement Canada (PSPC) is building on the National Research Council (NRC) Montreal Road campus under the Laboratories Canada strategy. PSPC lists the value at about $1.05 billion, with AECOM as designer and EBC as construction manager, and says major construction began in summer 2026 after a July groundbreaking.^[1]

Component 1 is a three-storey laboratory and office building of roughly 33,000–33,500 square metres for approximately 490 full-time staff. It sits between Mackenzie Drive, Ballard Drive and Blair Road and is designed to house programs from Natural Resources Canada’s Geological Survey of Canada and CanmetMINING, plus the Canadian Nuclear Safety Commission (CNSC). PSPC’s project description explicitly includes “a Class II nuclear facility” among the specialized spaces, alongside modern laboratories, geoscience and mineral processing facilities, and collaborative workspaces.^[1]

A Class II nuclear facility, under Canadian Nuclear Safety Commission rules, is a facility that contains Class II prescribed equipment—typically certain high-activity irradiators or particle accelerators below specific energy thresholds. These are common in research and regulatory laboratory settings and require their own CNSC licences to construct and operate. They are a lower regulatory category than Class I facilities such as nuclear power reactors. The facility is intended to support nuclear safety research and oversight as well as the critical-minerals and resource-development work of the partner organizations. The campus is also receiving a Transportation Safety and Technology Science hub on the north side, where main construction is under way.^[2][3]

None of the high-level facts are in dispute. The murkiness starts when you look for the details behind them.

1. Which approvals are actually in hand?

The NCC’s September 2025 submission recommended approval of the 100% schematic design subject to conditions: early works under a separate federal review, and the developed design to return to the NCC.^[2] NCC materials for the October 2026 virtual board meeting now state that the board has approved the 100% Developed Design for Component 1; presentation and submission documents are posted on the NCC site. This closes one of the earlier gaps.

What remains less transparent is the precise list of conditions attached to that approval, the public record of any separate early-works approval that preceded the July 2026 groundbreaking, and the status of the separate CNSC licensing process required for the Class II nuclear facility.

2. The environmental assessment that is still “in progress”

The federal Impact Assessment Registry lists TerraCanada National Capital Area (TC NCA) – Phase 2 (reference 89958), with PSPC as proponent and the NCC and NRC as authorities. The assessment started 2 March 2026; the public comment period closed 1 April 2026. As of mid-November 2026 the registry still shows the assessment as in progress and contains no Notice of Determination on whether the work is likely to cause significant adverse environmental effects.^[5]

Labelling remains confusing (Phase 1 enabling works notices sit alongside Phase 2 materials; NCC documents speak of “Components”). Construction has nonetheless begun. The registry may lag, but a project of this scale—and one that includes a Class II nuclear facility—should make the determination (or a clear explanation of its status) easy to find. The Class II facility will also be subject to its own CNSC licensing process, which sits alongside the Impact Assessment Act review.

3. Getting there: transit, parking and the roads

Component 1 is planned with 143 on-site parking spaces plus 53 more in an existing campus lot—196 in total for about 490 staff. By my arithmetic that is about 0.4 spaces per employee, which only works if many people arrive by transit, bike or on foot.^[2]

The NCC’s own design advisory panel told the proponent to coordinate with the City of Ottawa and OC Transpo to improve transit access and to provide interim active-mobility solutions, and to revise the geometry of the new north-south road to avoid dangerous vehicle movements. The NCC submission describes staff-level engagement with the City and OC Transpo as ongoing.^[2]

The City has done its own homework on the corridor. A Montreal-Blair Road transit priority study found most intersections working well in weekday peaks but pedestrian and cycling facilities in need of improvement, and it expected LRT, intensification and the build-out of Wateridge Village to change travel patterns. What remains hard to find is a construction schedule or full funding for those corridor works. Nor did I find a transportation impact assessment for the campus build-out as a whole (TerraCanada plus the Transportation Safety hub plus longer-term master-plan growth).

4. Water, sewers, power and the nuclear facility

The enabling works are substantial: a new connection to the City’s water main on Blair Road, relocation of a sanitary sewer, new storm sewers and stormwater ponds, relocation of a channel and culvert, realignment of Ballard Drive, relocation of existing utilities, a geothermal field, and electrical, gas and telecom duct banks. That tells you what is being built. It does not tell you whether the existing systems have the capacity, or what upgrades were needed upstream.

The electrical picture is thin. I found no published electrical load for the new lab (including any specialized demand from the Class II nuclear facility), no capacity confirmation from Hydro Ottawa or Hydro One, and no statement on backup supply. The wider grid is under pressure. None of this proves a problem at Montreal Road. It does show why a published servicing and power plan matters.

Separately, the Class II nuclear facility will require its own CNSC licences to construct and operate. Those licensing documents and any associated public comments or decisions are not yet easy to locate alongside the NCC and Impact Assessment materials.

5. The cumulative picture

The NRC campus master plan, approved by the NCC board in April 2024, is a 30-year vision for a 123-hectare site. TerraCanada Component 1 was designed with a future Component 2 in mind, including consolidated servicing and stormwater provisions, and a second hub is going up on the north campus. Each project is reviewed in turn. I could not find a single public document that adds up the staff, traffic, water, sewer, power demand, and specialized nuclear-related activities across everything the master plan allows. That combined view is what residents of Rothwell Heights, Wateridge and the surrounding neighbourhoods would need to judge the project fairly.

Questions worth asking

1. What exact conditions did the NCC attach to the October 2026 developed-design approval, and where is the public record of the early-works approval?
2. Has the federal authority issued its determination under the Impact Assessment Act for Phase 2, and where is it posted? If not, why has major construction proceeded?
3. What is the status of the separate CNSC licensing process for the Class II nuclear facility, and where are the public documents?
4. Is there a transportation impact assessment covering the full campus build-out, and what did it conclude about Blair Road and Montreal Road?
5. What specific transit and active-transportation commitments have the City and OC Transpo made, and are the Montreal-Blair corridor works funded with a construction timeline?
6. What is the projected electrical demand of Component 1 (including any specialized loads from the Class II facility), and have Hydro Ottawa and Hydro One confirmed capacity in writing?
7. What is the plan if parking overflow reaches the residential streets east of Blair Road?

A note on limits

This post is based on publicly available documents located through web searches on 14 November 2026. Not finding a document is not proof it does not exist, and some registries and board pages update slowly. If PSPC, the NCC, the NRC, the CNSC, the City or the utilities can point to documents that answer these questions, they should publish them in one place. The parking ratio is calculated from the figures in the NCC submissions. Contact for Laboratories Canada: tpsgc.laboratoirescanada-laboratoriescanada.pwgsc@tpsgc-pwgs c.gc.ca.
