Prior to joining The Centre of Forensic Sciences in January of 1968, I served three years in the 2nd Battalion The Canadian Guards in the Canadian Army.

During that period, I passed a Junior Non-commissioned Officers Course and served on the Rifle Team. Upon joining the laboratory, I completed a two-year training syllabus, which included specialized training in:

• Firearms and Toolmark Identification
  
• Standard Laboratory Techniques
  
• Microscopy
  
• Photomicroscopy
  
• Distance Determination

I have visited various Forensic Laboratories in Canada, the United States, Europe and South Africa in order to study their techniques.

I have also visited various firearms and ammunition manufacturing plants in Canada, the United States, Europe and South Africa in order to study their techniques in the manufacture of firearms and ammunition.

As part of my duties, I have lectured on Firearms Identification to the following groups:

I have also given instruction on all types of Small Arms to the following groups:

I am a qualified Range Safety Officer with the Canadian Armed Forces as well as an Honourary Small Arms Instructor at The Canada Armed Forces School of Infantry in New Brunswick.

I am a 'Distinguished' member of The Association of Firearms and Toolmark Examiners and have been a member since its inception and also a member of The Canadian Society of Forensic Sciences.

Personally, I have collected and studied firearms and ammunition since 1959.

I am a member of three Canadian, one American and one European Firearms Collector Associations.

I have testified at all levels of Court in The Province of Ontario for Defense and Prosecution over 1000 times, and on several occasions in the United States and Bermuda respectively.

I was promoted to Section Head of the Firearms Section on December 1, 1981. I retired on November 29, 1996.
