Lewis's proposals seem reasonable to me. On one hand you can't just have a destabilizingly high rate of immigration, but on the other it's extremely unjust to just deport a bunch of people who are already here, Trump style. We need a reasonable level of immigration as well as protection for refugees - this century is going to see a massive influx of refugees in general, and if we become Festung Kanada it will rot us from the inside out.
