In 2000 a Canadian Warship Sank Prematurely Off Mission Beach – What Happened Then?
HMCS Yukon Was Bought by San Diego to Eventually Scuttle for an Artificial Reef
By Team Global / The Economic Times / August 31, 2026
In 2000, the City of San Diego, working with the San Diego Oceans Foundation, acquired and refurbished HMCS Yukon, a decommissioned 366 foot Canadian warship, to scuttle it as an artificial reef about 1.85 miles off Mission Beach. However, there were some issues with the actual sinking of the ship. On July 14, 2000, the ship unexpectedly began to capsize and sank before divers could position it properly, settling on the seafloor at depths ranging from about 60 to 105 feet.

After the Yukon was sunk, one pressing concern that arose for researchers was whether an artificial reef such as this one truly contributed to the production of marine life or merely drew fish populations that were already living elsewhere into the vicinity of the reef.

A person was found aboard a sailboat that was trapped on rocks near the Ocean Beach jetty early Tuesday, Sept. 1, and was taken to the hospital in unknown condition.
