Investigator's Guide to National Forensic Laboratory Services

This guide assists police investigators with the collection, preservation, and shipping of physical evidence to the RCMP's National Forensic Laboratory Services (NFLS), which operates as a single public laboratory system with three sites located across Canada.

In addition to providing investigators with general information, this guide provides examples of some common exhibit types that are submitted to the different forensic service areas at NFLS – biology (DNA), toxicology, trace, counterfeit, and firearms. There could be other types of evidence not identified in this guide.
