About Our Mechanical Engineering Services Team

Design and engineering of building systems — new and existing

RoMar is a mechanical consulting engineering firm operating out of Durham Region with projects stretching across the GTA and much of Ontario. The company is owned and operated by two female professional engineers — Jolanta McKay and Margaret Edwards. Together, they have a combined 35 years of experience working in the building services industry.

RoMar’s work involves the design of mechanical systems including HVAC, plumbing and fire protection systems for new and existing buildings. RoMar offers a full range of engineering services including design, construction administration, energy audits, commissioning, re-commissioning, energy modeling and prime consultant/project management. We have performed work in the industrial, commercial, healthcare, institutional, and multi-residential sectors. We have considerable experience in existing buildings where retrofits are required to bring the building up to date and provide energy savings for our clients.

RoMar considers the mechanical engineer a vital member of the design and construction team; and we enjoy being a part of that team.

The company has been serving the building industry since 2000 and has earned a reputation for unique and personalized designs and services.

Jolanta Mckay, P. Eng., CBCP

Jolanta brings over 25-years of valuable experience in HVAC and mechanical building systems design and operation, as well as energy efficiency in a wide range of projects.

Combining her design experience with energy efficiency and systems operation, Jolanta provides a high-quality, well-rounded and sustainable service to her clients. Her design methodology is to focus on proper systems operation under various conditions, systems efficiency, diversity and longevity tailored for your unique building.  She takes pride in commissioning each project at the end of the construction stage to ensure the best final operation of the systems when turned over to the client.

Jolanta attended the University of Warsaw in Poland where she received a Bachelor of Mechanical Engineering and a Masters in Applied Sciences. Jolanta is CBCP (Certified Building Commissioning Professional) certified.


Margaret Edwards, P. Eng.

Margaret is an enthusiastic senior mechanical engineer and project manager bringing over 7 years of experience in the industry. Her exceptional communication skills and excellent organizational skills ensure that our client’s goals are determined, defined, and met or exceeded on a consistent basis.

Margaret graduated with Honours from the Mechanical Engineering program at Queen’s University.  Prior to joining RoMar, Margaret was involved with the mechanical design and project team for many mid and high-rise multi-use residential buildings in the GTA. Margaret has also been involved with many interior fit-up projects for some of Toronto’s finest office towers including the Exchange Tower, First Canadian Place and 2 Queen Street East. She has acted as the team lead for mechanical design, primary consultant and project manager for a variety of projects for property management companies and their commercial buildings. These include projects such as large equipment replacements, parking garage retrofits, boiler plant retrofits, and cooling tower replacements.


Margaret received extensive training in mechanical control systems from her previous role working in Building Automation technical sales. Margaret also had the opportunity to work for an HVAC equipment manufacturer where she gained extensive knowledge on industry equipment (i.e., chillers and roof top units).  

Margaret is passionate about her work and connecting with her clients. She strives to develop the best possible design solution for the building, the people it serves, and the people operating it.
