I don't know what the process is. It would be up to the government what it is doing to review them. There are problems here for employers and workers and everything else.
With the zones, some employers are having problems employing people, because they'll ask which zone someone lives in. If someone lives in one zone and the employer needs them for seasonal work, they know that person is going to require more weeks of work than they can offer. It's a whole mess, and they can't get the same workers back each year and this type of thing. Everybody's complaining about the system.
