Bayside Aero’s roots started in 2011 when the flight school and AMO closed their doors at the small airpark in Guelph, Ontario.  Ron Mercer had been working as Chief Engineer for the school since 2001, so he and his wife decided to start an AMO to provide service to the aircraft owners and operators in Guelph and the surrounding area.  In 2011 R & D Aviation began.


Eventually Ron and Deb moved to Grey County after falling in love with the area.  As they gained customers in and around Grey-Bruce, Ron continued to commute back and forth to Guelph to maintain the aircraft of their loyal customers.


In 2018, Ron, partnered with Brad Muehlbacher, decided to move the base to Wiarton and rebranded the company as Bayside Aero. Since then, Brad has taken over management of the AMO, allowing Ron to enjoy semi-retirement while still doing what he loves most - fixing your airplane!


Today, Bayside Aero is a growing company, providing maintenance to aviation enthusiasts and commercially operated aircraft in the region.  You can find our hangar at Wiarton Keppel International Airport, which has been growing since Georgian Bluffs assumed ownership in 2015.  Bayside Aero is proud to offer service to the area, while only a short flight away from the rest of Southern Ontario.


Ron enjoyed a 23-year career with the Canadian Armed Forces working on multiple aircraft types including turbine, radial, floatplanes, and rotary wing.  In 1985 he was one of the very few to earn his AME license while still serving in the C.A.F.  Since retiring from the military, he has held the position of Director of Maintenance for several flight schools including Airline Training Resources (International), The Flight Academy, Prism Aviation, Aviation International, and R and D Aviation. Today he enjoys semi-retirement; giving him the time he needs to spend with his plethora of grandchildren while still keeping his hands dirty.


Brad started his career as an apprentice under Ron in 2000.  After getting his AME license in 2004, he left the flight school in Guelph to explore new experiences within the aviation industry.  He spent some time working on turboprops and light jets but soon found a love for rotary wing.  His 20 years of experience varies, with everything from fieldwork to light and heavy maintenance on a wide array of aircraft for companies including Aviation International, Flight Exec, Heli-Lynx, National Helicopters, Canadian Helicopters, Kelner Helicopters, and TransCanada Pipelines.  His passion for the outdoors inspired him to move his family to the Bruce Peninsula and pursue his vision for a quality maintenance hub in the region.
