The seabed is not for mining
The Metals Company will apply to the International Seabed Authority (ISA) for a permit to mine the deep seabed on June 27, 2025. This application will be the first submitted for deep seabed mining (DSM) in international waters. There are no approved regulations.
Canada must refuse mining applications made through the ISA while there are no approved mining regulations; Canada must insist on regulatory provisions that respect Indigenous rights to grant or withhold consent; Canada must legislate a ban on DSM in Canadian territorial waters and actively support global calls for a moratorium on DSM in international waters.
