Beyondhelp , I believe with the serious crimes we are looking at, which fall under criminal, the below excerpt may answer your question in regards to limitation. I believe management, the regulators, the governments etc, may be beyond help......

Canada[edit]

For crimes other than summary conviction offences, there is no statute of limitations in Canadian criminal law. For indictable (serious) offences such as major theft, murder, kidnapping or sexual assault, a defendant may be charged at any future date;[15] in some cases, warrants have remained outstanding for more than 20 years. The sole exception is a charge of treason, which must be brought within 3 years.[16]

Civil-law limitations vary by province,[17] with Ontario introducing the Limitations Act, 2002 on January 1, 2004.[18]
