To be honest, it should be the employers who SHOULD raise their voice. No employers were complaining to the Canada’s government, so they thought they’re not having trouble.
Because just like a normal human being, why would I be bothered by someone’s application if you’re NOT HERE IN CANADA. Canada doesn’t care for someone who is not here yet, unless you’re in a warzone. If your employer is not complaining, then Canada is still all right. This is the reason why they don’t take this as priority. So no matter how outside Canada applicants complain, they are not bothered. Canada can still thrive even without nannies, as shown by employers’ silence.
My two cents…
