This is the entry level Chief Mate’s certificate. It is hands down the most easily attained Transport Canada “unrestricted” licence.
Holders of the “150 Mate” can serve as Chief Mate on vessels of up to 150 GT, and serve up to 25 NM from shore (Near Coastal 2) as well as all navigable waters included in the Great Lake’s Basin. With certain sea-time accruments (see Marine Personnel Requirements) you can get a “Limited, Contiguous Waters” endorsement which allows greater voyaging range than Near Coastal 2, but not quite the range of NC1.
Additionally, this certificate allows the holder to serve as Chief Mate on vessels up to 500 GT vessels within Sheltered Waters (which includes Toronto Harbour).
