My preference would be a complete halt to immigration and the reallocation of immigration-related funding to be used instead to pay Canadian families to have children at above replacement rate. I would need to see data comparing the effective contributions of immigrants of European/English decent, vs. non-English speaking arrivals, as well as some sense of the undoubtedly large cultural cost to increased diversity, in order to accurately assess this question. My preference would be to reject anyone outright who did not have significant cultural overlap with the founders of this country, meaning French or English would be one of may bare minimum expectations for immigrating. What little remains of the cultural identity of Canada (going back as recently as the 1990s) lies festering and we cannot afford any more progressive colonization
