Given Canada's location, geography, and its present borders, the only places where legitimate refugees could potentially come from are quite limited: the United States, St Pierre and Miquelon, Greenland, and possibly Iceland. At the current time, there's generally no legitimate reason for people from those places to be seeking asylum in Canada. Legitimate refugees will be seeking immediate safety far closer their points of origin, rather than ending up in Canada, of all places. Sri Lanka, to use your example, is over 12000 km (7500 miles) away from Canada, in either direction. At the time of the incident you mention, there were numerous safer countries that were much, much, much closer to Sri Lanka than Canada was. Those are the countries where those people should have ended up, if they were truly seeking immediate safety as legitimate refugees.
