US federal OSHA: 29 CFR Part 1904 covers recording and reporting injuries and illnesses, not investigations; some states require investigations (for example Oregon, OAR 437-001-0760). Keep the OSHA 300 Log, 300A summary and 301 incident reports (or equivalent forms) for 5 years after the end of the year they cover (29 CFR 1904.33); if you use this report as your 301 equivalent, keep it for 5 years. In Canada, investigation, reporting and retention rules are set by your province or territory, or by the Canada Labour Code for federally regulated workplaces.
