"Most North American law enforcement authorities require that original, unaltered documents be available if requested by an officer. In B.C., this requirement is contained in the Motor Vehicle Act."
If you do have your vehicle registration or driver’s licence stolen, your first step should be to report this to police.
You should then call ICBC. It will place a note on the customer’s file and your broker can get replacement documents. As well, it’s recommended that you monitor your financial statements for any unauthorized transactions.
20さんが引用してくれた2013年の記事では「In B.C., this requirement is contained in the Motor Vehicle Act.」とのことですが、26さんのレスを見て気になり、BC州の MOTOR VEHICLE ACT [RSBC 1996] CHAPTER 318 を改めて見てみました。
私が見たのは、MOTOR VEHICLE ACT「This Act is current to August 8, 2018」となっていて、パっと見では「original, unaltered documents」を車の中に保管しておかないといけないとの記載は見つかりませんでした。
