I certainly wouldn't sacrifice the economy for ideological reasons, but I would say that in the absence of a temporary foreign worker program, I would expect—as I've said already—that firms would readvertise at a higher wage rate. They might attract Canadian citizens or landed immigrants to the jobs, or they might invest in new technology.
The Nobel Prize in economics was awarded last week, I think, to Peter Howitt, an esteemed professor at Brown University, who taught at Western University for many years. Their theories are about “creative destruction”—that new companies come in and replace old companies. There are papers in that literature that basically say that if you protect companies that rely on low-wage workers, they will invest less in innovation and new technology, and you'll short-circuit that growth.
These are the concerns I have. It's the impact for younger, low-wage workers in Canada, Canadian citizens and landed immigrants, and what the implications are for economic growth for the country.
