Suppose for a moment that 15 million Americans -- the population of Massachusetts, Maine, New Hampshire, Vermont, Rhode Island, and Connecticut combined -- sneaked across the border into Quebec. Suppose that these illegal immigrants refused to learn to speak French, that they applied for Canadian welfare, that they reproduced at a rate higher than Quebec's residents, and that they bankrupted Canada's socialized medical system. Suppose that they sent their children to Canadian schools in such large numbers that Quebec's school system had to teach "French as a Second Language" courses.
Suppose that the 15 million illegal American aliens included large numbers of criminals, drug dealers from Vermont, and arms traffickers, causing Quebec's crime rate to soar; that they comprised 20% to 30% of Quebec's prison inmates; and that they routinely evaded capture by Canadian authorities by sneaking back across the border, where they engaged in gang warfare.
Suppose that the illegal Americans congregated in packs on Montreal street corners, looking for day labor for which they did not pay taxes, and drove through the streets of Quebec without driver's licenses or motor vehicle insurance. Suppose that the illegals marched openly in the streets of Montreal, waving the Stars and Stripes, celebrating the Fourth of July, and demanding amnesty. Suppose that illegal American college students formed radical pro-U.S. organizations on Quebec's campuses and demanded resident tuition discounts and affirmative-action preferences.
Let us further suppose that when the Montreal Canadiens played the Washington Capitals at the Bell Centre, large numbers of illegal Americans waved the American flag, booed, hissed, and doused Canadiens fans with beer when "O, Canada" was sung in French prior to the opening face-off.
How do you suppose Canada would react? Would Quebec City and Laval declare themselves "sanctuary cities" and refuse to cooperate with federal authorities seeking to deport the illegal Americans? Would Quebec offer driver's licenses to the illegals? Would the province refuse to ask voters for identification and proof of citizenship?
If Quebec's provincial parliament passed a law allowing the police to demand proof of citizenship from suspected illegals, would the Prime Minister call it "misguided"? Would the Bishop of Montreal accuse the province of "Nazism"? Would residents of Calgary and Winnipeg call for a boycott of Quebec? Do you suppose the federal parliament in Ottawa would propose legislation to grant citizenship to the illegals (thereby allowing them to sponsor the emigration to Canada of their relatives back in the Unites States)?
Of course not. Anyone remotely familiar with Canadian politics knows exactly what would happen. A situation like the one described above would cause the province to explode.
