The ministerial order power for proposed section 107.1 only allows the minister to make an order to require a port authority or a person in charge of a port authority to take any measure. In situations where there's an ability to order workers back or to order some form of arbitration, it would apply to those individuals, or even potentially to any person, if it were that broad.
This particular formulation states that the minister can only, by order, require a port authority or a person in charge of a port facility to take any measure. It's really not targeted at workers at all. It doesn't allow the minister to order unions or workers back to the table or to binding arbitration. It wouldn't relate to strikes or lockouts in any way. From that perspective, it is distinct from labour legislation, including Bill C-58.
