I think the first step is to identify the actions that are needed to close the pathway and, if you're referring to transport from one area of Canada to another, identifying the appropriate role for the federal government and also the provincial governments.
Non-governmental organizations, as we've heard already, can play a role at some of the points where people are leaving lakes that are already contaminated with invasive species by working with lake associations, for example, and building awareness, so that behaviours are changing. If people are aware of the consequences of moving invasive species, then that kind of peer pressure or assertion of social norms, such as the importance of cleaning your boat, is the way that associations such as lake associations and community associations that are near lakes that have invasive species can make a contribution.
