CCG is constantly replacing old ships with a newer version as is mentioned below:
but what does the CCG do with the old ships? Many are sold for scrap (eg CCGS Camsell) but this man found out what he wanted to do with one that was decommissioned:
Businessmen to revive former Coast Guard ship June 6, 2014
Donatelli and Terrio are considering using it as a tour boat for perhaps 50 – 60 people and note a refitting and a raft of permits would be needed.
If it sees that new life, it could tour areas around Niagara or Toronto, and be in service by next summer. . . . more
So, if you need a new boat, or any other item that you have seen in Coast Guard service, just go to the Government of Canada Surplus (GCSurplus) website and make your selection.
