June 09, 2025 [Offshore Technology]- Irving Oil has announced a $100m (C$136.81m) investment to upgrade a key crude oil processing unit at its Saint John facility in New Brunswick, reputed to be Canada’s largest refinery.

The modernisation effort, known as the FCCU Revamp Project, aims to enhance the unit’s performance, efficiency and reliability.

Opened in 1960 and spanning 780 acres, the refinery plays a pivotal role in supplying fuel products across Atlantic Canada and the US north-east.

The privately funded project is set to bring in approximately 675 skilled workers, primarily from New Brunswick and neighbouring provinces, bolstering local employment.

Irving Oil president and CEO Jeff Matthews added: “As we build for the future, we do so with the knowledge of continued growth in demand for traditional energy products. This FCCU Revamp Project is an essential investment in energy security for all the regions we serve. This private investment honours our past and ensures a strong future for Irving Oil and our region, as we continue to operate Canada’s largest refinery and provide a safe and reliable supply of energy in critical markets.”

The work, which begins this month, will be executed in phases throughout the summer and autumn.

The influx of additional tradespeople including labourers, scaffolders, pipefitters, boilermakers and insulators, is anticipated to generate estimated direct and indirect economic benefits of $3.5m in New Brunswick.

Lorneville Mechanical is one of the contractors and suppliers providing support on the upgrade project.

Irving Oil specialises in the refining and marketing of finished energy products. The company operates the Saint John refinery and Ireland’s only refinery, situated in the village of Whitegate.
