Canadians need perspective on our new world on the move. Tens of millions of people now flow into and out of Canada each year mainly by land and air. Border examinations are necessarily superficial. The number who stay and work illegally is not known. In this context, despite the passions aroused, a few hundred people arriving irregularly by boat is not itself a major problem.
Smuggling is a more serious matter.
The boat story is likely part of Canada's public information program. Sadly, Canada does not promote the rights of migrants. This is a concern for their home countries with which Canada must cooperate to prevent the trafficking. Several migrant home countries have ratified the UN Convention on the Rights of All Migrant Workers and Members of their Families. Receiving countries like Canada have not.
