"Canada has even co-opted the 'we are a nation of immigrants' thing." Indeed. It looks like Trudeau got inspired by Angela Merkel's "welcoming culture" for migrants, imposed upon the Germans back in 2015. Chances are that many migrants, whether genuine refugees or those on the move for economic reasons, will feel highly encouraged to make their way to Canada fairly soon following Trudeau's warm words of encouragement: not good. It does appear as though many migrants from developing countries first travel to Latin America in order to proceed up to the US (where Trump has now made things a bit harder) and then to Canada. Those bland Canadian border guard shifts may soon be a thing of the past, they had better get ready for the impending stampede, and order plenty of flowers for the numerous welcoming ceremonies, Germany-style.
