That's probably a question that Allan could offer perspectives on. In terms of the number of foreign-flagged vessels that enter Canadian ports, I think it varies from year to year. They aren't huge in number. I think they typically number in the dozens. I'm not sure that they've ever numbered over 40 or 50, so we're not talking about an enormous number of vessels, although Allan may be able to answer more precisely.
