Certainly.
I will answer in English, if you don't mind.
I think we would have a couple of really good recent examples.
In terms of the whale situation on the east coast, there is a system in which we've implemented various voluntary measures, specifically whale watch reporting, wherein our captains report back to government ship by ship. Until the mandated slowdown, we in fact were doing a voluntary slowdown. It was effective on the east coast. It's been very effective farther down into the Bay of Fundy, where we also brought in a system of voluntary route changes. The evidence suggested after the fact that these, in fact, were more effective than slowdowns.
Also, up at the Saguenay fjord in the St. Lawrence estuary, again on a voluntary basis, we've been reducing speed in whale feeding grounds and frequently avoiding sensitive areas where beluga whale herds are composed of females and young. On a voluntary basis, speed reductions through 2013 to 2016 resulted in a nearly 40% reduction in the risk of ship collisions with whales.
I could go on. There are other examples where I think voluntary measures have worked very effectively.
