We're proposing a three-tier approach. Tier one is with ships or companies that are pursuant to the SOLAS Convention. They are currently subject to the safety management regulations. Those are ships that will conduct international voyages.
Tier two is with vessels that are not subject to SOLAS, have more than 500 gross tonnes, and/or are certified to carry more than 50 passengers. The companies that operate them will be required to implement SMS and to have it audited and certified.
Tier three is with vessels that are more than 24 metres in length and less than 500 gross tonnes. Those companies will be required to implement SMS but will not be required to have it audited and certified. The philosophy behind this is that we want to improve safety while not causing undue harshness on companies, because those things could be very costly to undertake—if you're talking about certifying and auditing, that could also be very costly—and to make sure that we do not also put undue administrative burdens on the companies that will be subject to that.
By putting in place those measures, we strongly feel that we're meeting the intent of the Transportation Safety Board and moving the yardstick a little farther in terms of improving safety in Canada.
