The report into the sinking of B.C. Ferries' Queen of the North will be released next week, the Transportation Safety Board said.
The ferry ran aground and sank in Wright Sound near Harley Bay in the early morning of March 22, 2006.
Two passengers were presumed drowned after the ferry sank, and three crew members have since lost their jobs. A total of 99 passengers and crew survived.
The 37-year-old ferry was off-track and had failed to change course, but there have been few other details released into the cause of the incident.
The TSB will release details of the report next Wednesday.
