Sure. When we look at shipyards' productivity in Canada and in the U.S., we find that productivity is lower in Canada. This is explained by the fact that we don't build as many ships as the U.S. shipyards do. They run a constant operation. They are building many, many more ships than our shipyards are building.
The lower productivity is also reflected in lower average hourly wages. So the cost of labour is also lower in Canada, but when you factor in the productivity differences, the wage differences and the exchange rate, the costs end up being significantly higher for building these ships domestically.
