Works well when it's easy to find a job, doesn't work well when you get fired for no reason and you were working in a profession where you don't just get a job the next week. Also there are more possibilities to employment than American "any time for any reason" and European "at least a month either way". In Canada you have to have a justified cause to fire people or just give notice, and for quitting you customarily give 2 weeks notice (I'm not even sure if you're legally bound to).
