Transport Canada describes CADORS entries as preliminary and unsubstantiated, and subject to change. Reports reach the system when somebody files one, so a clean record doesn't prove an aircraft has never been damaged. It doesn't replace a title search, an AD check, a pre-purchase inspection or the logbooks. One entry has a Transportation Safety Board file number; those are investigated separately and the TSB publishes its own reports.
