Alain Charron graduated from the Royal Military College of Canada (RMC) and has served the Canadian Military both as an officer of the military and as a civilian.

As an officer, Alain was, among other things, part of a group investigating the environmental condition of CFB Lahr in Germany before the Canadian government was to return the land to Germany. He retired from the military in 1992.

Following his military years, Alain continued to serve the Canadian Forces as a civilian doing research in the RMC structural engineering laboratory. During those years, he was published numerous times both as an author and co-author in engineering publications such as The Canadian Journal of Civil Engineering. Following his findings in a research project, he was instrumental in having part of The Wood Design Manual changed to better reflect the compressive properties of wood in construction.

As a member of the Property Inspection Network Limited since 2001, Alain specializes in both pre-purchase home inspections and residential energy audits. He has now completed over 5000 inspections and energy audits in Eastern Ontario and western Quebec and has assessed structures, mechanical systems, insulation, interior and exterior finishes, roofing, chimneys, and building envelopes. More recently, Alain has been an expert witness in construction-related issues and slip-and-fall incidents.
