Just to add one point to the previous question in terms of raising the tug, I think one of the key challenges and issues in this particular circumstance is the depth of the water that the tug is resting in. It's quite deep, which puts people at risk bringing it up. It's a situation where these factors have to be taken into account by the Coast Guard.
In terms of the issue of incidents with tugs, it is an area where Transport Canada has taken note of the fact that there are incidents that happen and that it's an area where we have increased our oversight activity in recent years as part of what I would call a risk-based oversight system in which we're always looking at where we see incidents and then try to move our oversight activities to address them.
I may turn to the ADM of safety and security, Kevin Brosseau, to speak a bit more about that.
