Welcome to Team Vigilance

Redefining Naval Excellence

Ontario Shipyards, in partnership with industry leaders such as Vard Marine, Thales Canada, SH Defence, and Fincantieri, is proud to announce our role in Team Vigilance. Launched at CANSEC 2023, this collaboration is at the forefront of naval innovation, crafting the next generation of naval vessels specifically designed to meet and exceed the demands of modern naval operators.

Our Role at Ontario Shipyards

At Ontario Shipyards, we are re-establishing Ontario Shipyards as a leader in Canadian shipbuilding. Our strategic involvement in Team Vigilance leverages the nearly one hundred years of shipbuilding tradition in Ontario and the industrial capacity of the province's manufacturing sector to build the future Canadian Multi-Mission Corvette.

"Ontario was once the epicentre of shipbuilding in Canada. We are now harnessing this capacity to deliver on the goals of the National Shipbuilding Strategy and support Canada's future naval missions."
Shaun Padulo, President and CEO.
