I think that's an excellent question. I'll ask some of my colleagues to leap in with maybe some specifics.
It is an area the government has put more money into in the last two budgets. The aerial surveillance has been increased. That's led by Environment Canada, but we actually make available our provincial airways. We have significant coastal patrol capability that we exercise off the east coast primarily for fishery enforcement reasons, but they also keep an eye open for this. There have been successful prosecutions. The last budget, I think under the oceans action plan, further increased the ability to do surveillance. But the whole area of invasives has got quite a positive injection of funding in the last few budgets.
Wendy, do you want to talk to some of the specifics?
