I think that Mr. Brunet dealt with the dredging issue well.
As for whether it would be possible for Canadian shipowners to compete in Europe if ever the market were reciprocal, the answer is no. As I mentioned just now, European vessels have much lower operating costs than ours.
There is another factor. Most of the Canadian fleet are lakers. The vessels are not designed to sail on the open sea, which is what you need to get to those markets.
Be that as it may, the main reason is that the operating costs are different from ours.
