Canada’s National Shipbuilding Strategy is the largest single procurement programme in the country’s history. Irving Shipbuilding in Halifax holds contracts to build six Arctic/Offshore Patrol Vessels and fifteen Canadian Surface Combatants, a programme spanning thirty years and more than $60 billion in shipbuilding value. That scale of sustained construction creates a specific kind of labour demand: machinists and welders who can work to marine tolerances, pass federal security clearance requirements, and commit to a career — not a project.
Irving Shipbuilding employs more than 2,400 shipbuilders at its Halifax Shipyard. The facility’s assembly hall stretches the length of four football fields and rises more than twelve stories, making it one of the largest indoor shipbuilding facilities in North America. The relevant occupations are NOC 7231 (machinists and machining tool operators) and NOC 7237 (welders and related machine operators). Both are Red Seal trades. Both are in sustained demand for the duration of the programme, which means a worker entering the shipyard today is entering a programme that will still be hiring when they retire.
What working on the NSS programme requires
Machining and welding on the NSS programme differs from the same trades in a general fabrication shop in several important respects. The work involves precision operations on marine-grade steel and aluminium, often in confined compartments or on elevated platforms within a partially assembled hull. Quality documentation is required on every significant weld. And the defence programme context introduces compliance requirements that general manufacturing does not.
All workers who handle or observe defence-controlled goods at the Irving shipyard require Canadian Controlled Goods Program (CGP) clearance, administered through Public Services and Procurement Canada. Workers must also meet International Traffic in Arms Regulations (ITAR) requirements that govern access to certain defence-sensitive technical information and equipment on the CSC programme. CGP clearance applications are typically initiated by the employer after a conditional offer, and processing takes approximately four to six weeks. These requirements apply broadly — on a warship construction programme, effectively every worker on the production floor falls within their scope.
Irving operates the Marine Trades Initiative, a specialized training pipeline that prepares welders and machinists specifically for marine and shipbuilding work. The programme has a formal partnership with Nova Scotia Community College, through which NSCC welder and machinist students complete five-week placement programmes at the Halifax Shipyard. NSCC Akerley Campus in Dartmouth is the primary institutional entry point into that pipeline. Irving separately recruits more than 100 Canadian Armed Forces veterans into trades roles each year, recognizing that military training backgrounds translate directly to the discipline and systems awareness that warship construction demands. The veteran pathway, for former CAF members with trades backgrounds, can accelerate the clearance and onboarding process compared to civilian applicants.
Training
The foundational credential for this pathway is a Red Seal in machining (NOC 7231) or welding (NOC 7237). Both require apprenticeship hours — approximately 8,000 hours over four years for machining, and between 5,400 and 6,000 hours over three years for welding. The Nova Scotia Apprenticeship Agency (nsapprenticeship.ca) administers both trades in the province and handles apprenticeship registration. NSCC Akerley Campus runs the in-school technical training components and is the most direct institutional connection to Irving’s hiring pipeline. Workers who complete the NSCC-Irving placement programme enter the Red Seal process already familiar with the shipyard environment and its documentation requirements, which is a material advantage at the hiring stage.
The CGP clearance process is not a background check in the conventional sense — it is a federal regulatory requirement under the Defence Production Act. Irving initiates the application on behalf of new hires, but the worker must provide detailed personal history documentation. Workers with international residency history in certain jurisdictions may face longer processing times. The clearance is portable between employers who are registered Controlled Goods registrants.
What the work pays — NOC 7231 / 7237
| Level | Hourly Rate (Nova Scotia) | Context |
|---|---|---|
| Apprentice (yr 1–2) | $22–$26/hr | In-training wage, supervised production work |
| Journeyperson | $26–$34/hr | NOC wage data, Nova Scotia; Red Seal qualified |
| Lead hand / senior | $34–$38/hr | Irving shipyard lead hands; quality and documentation responsibility |
| Supervisor | Above $38/hr | Trades supervision, planning, compliance oversight |
Wage data for NOC 7231 and 7237 in Nova Scotia is drawn from Statistics Canada’s occupational wage survey. The Irving programme, as the dominant employer in marine trades in Atlantic Canada, effectively sets the market rate for the trade in the Halifax metro area.
The Halifax context
Halifax was among Canada’s fastest-growing cities by population percentage in both 2023 and 2024, driven substantially by interprovincial migration and Atlantic immigration programmes. Housing costs have moved significantly since 2021. Workers relocating to the Halifax metro area for Irving employment should plan for competitive rental conditions. Dartmouth — adjacent to NSCC Akerley Campus and within commuting distance of the Halifax Shipyard — has generally maintained lower average rents than Halifax proper, though both markets have tightened. The 30-year programme horizon creates unusual stability in the local labour market context: workers are not moving to a project location. They are moving to a programme city.
The long view
The Canadian Surface Combatant programme runs to 2050 at minimum. The Arctic/Offshore Patrol Vessels are in advanced construction. Workers who enter the Irving programme now are entering a system that will sustain skilled trades employment in Halifax for the length of a full career. Unlike automotive or aerospace supply chain work, this employment is not exposed to tariff volatility, offshoring risk, or platform cycle uncertainty — the ships are being built in Halifax because Canadian sovereignty policy requires it, and that requirement does not change with trade negotiations. The NSS Watch page tracks supply chain openings across both the Halifax and Vancouver programmes on an ongoing basis.
