“The Canadian Forces National Investigation Service seeks to investigate and where appropriate lay charges based on factual evidence regardless of when the offence is alleged to have been committed.  Much care is taken to investigate all matters of this nature, historical or otherwise. 

CFNIS investigators continue to pursue all investigatory leads even after a charge is laid.  When new information is discovered which impacts on the basis for which the charge was laid, such information will form part of the continual assessment as to whether any given charge will be sustained.”

Lieutenant-Colonel Kevin Cadman, Commanding Officer, Canadian Forces National Investigation Service
