It used to take an outright invasion to gain control of another country.  Now it's done by immigration and multiculturalism.   

In 50 years, Canada will have no connection to our past, no great-grandfathers who fought in WWII to preserve our way of life, no ancestors who braved the cold and starvation to settle our great nation.
