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......
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]
