Housing is a municipal jurisdiction, healthcare is a provincial jurisdiction and immigration (direct, temporary, students, refugees) is a federal jurisdiction (except Quebec has its own immigration jurisdiction).
Bringing in millions of people in a short time without coordination with other jurisdictions to manage housing demands, healthcare demands and needed infrastructure upgrades was grossly incompetent.
Not quite on the epic scale of incompetence as Chairman Mao and eliminating the Sparrow (in terms of consequences) but equally as idiotic in terms of narrow minded thinking.
