Engineering Ontario’s buildings since 1997
A senior, multidisciplinary team with the technical depth of a large consultancy and the responsiveness of a firm where you know your engineer by name.
From complex public buildings to Ontario’s next generation of housing
Miriton was founded in Ottawa in 1997 to provide complete mechanical and electrical engineering services for buildings. For nearly three decades we have delivered projects where the stakes were high: occupied federal buildings, a national research laboratory, data centres, college campuses and heritage landmarks.
We have also designed residential buildings, industrial facilities, offices and commercial projects for private developers and contractors across Eastern Ontario. Today we are bringing that same rigour to Ontario’s builders and developers, from our Ottawa head office and our GTA office in Durham Region.
Environmental services, including Phase I ESAs and indoor air quality, are provided by our sister company, InAir Environmental.

The people who will work on your project
220+ years of combined experience across mechanical, electrical and architectural disciplines.
Ralph Siciliano
Ralph leads Miriton’s mechanical engineering and is the main point of contact on the firm’s largest projects. A Certified Energy Manager and LEED Accredited Professional, he takes projects from concept and energy analysis through design, permits, construction review and occupancy, including complex HVAC projects in occupied facilities and energy-efficiency programs. Clients rely on him to deliver on tight schedules without compromising performance.
Andrei Bosca
Andrei worked as an installing electrician and then as a Master Electrician for seven years before moving into engineering. He leads Miriton’s electrical design, including lighting, fire alarm, emergency power and distribution, with drawings built around how systems actually get installed.
Farzad Hatam Ardestani
Farzad manages projects from kickoff to close-out, coordinating the design team, sub-consultants and specialty contractors. His work spans condition assessments, feasibility studies, HVAC, plumbing and controls design, and air balancing.
Terry Barber
Terry holds a bachelor’s degree in civil engineering from the University of Ottawa, studied architectural technology at Algonquin College, and holds Building Code Identification Number (BCIN) qualifications. He leads architectural, building envelope and accessibility work, including the complete contract documents for a new, fully accessible border crossing building.
Josac Marcotte
Josac handles site surveys, mechanical design, code analysis, cost estimates and construction support. His work ranges from clean rooms to heritage sites, and he keeps critical-path items on schedule.
Soheil Yazdani
Soheil has designed building services for many of Miriton’s private-sector new builds, including residential buildings for Ottawa developers and home builders, industrial facilities, offices and a seniors residence.
Roland Ding
Roland brings four decades of HVAC and plumbing design and CAD experience, from library and community centre heat pump replacements to building condition assessments across 43 housing buildings.
Tonni Deb
Tonni produces CAD drawings, supports site surveys and prepares as-built records across government, restaurant and commercial projects.
Miriton and InAir Environmental: one coordinated team
InAir Environmental shares its Ottawa office with Miriton. Together we cover the engineering and environmental sides of a project, so developers, owners and lenders deal with one coordinated team instead of juggling separate consultants.
That means Phase I ESAs alongside building condition assessments, indoor air investigations alongside ventilation design, and designated substance surveys alongside renovation engineering, scheduled together and reported consistently.
InAir Environmental services
- Phase I, II & III Environmental Site Assessments
- Record of Site Condition (RSC)
- Excess soil management
- Groundwater & dewatering
- Designated substance & hazardous materials surveys
- Abatement specifications & monitoring
- Indoor air quality, mould & radon
- Drinking water & Legionella
- Planning & approval studies
- Environmental compliance & permitting
Backed for the long term
Miriton Ltd. is owned by Rue du Monde Holdings Ltd. Under this ownership, Miriton keeps the senior engineering team and expertise its clients rely on, while investing in the people, systems and reach to serve more of Ontario’s builders and developers.
Abhinav Syal
Abhinav’s career spans investment banking, enterprise management, sustainable development and the construction industry. He built his foundation in investment banking, learned to lead and grow organizations through enterprise management, and advised on sustainable development as a consultant. Through work with construction clients across the country, and as founder of Rue du Monde, he knows how projects are planned, financed and delivered. He brings perspectives from finance, marketing and technology to Miriton: disciplined costs, dependable schedules and a clear focus on what each project needs to succeed.
How we work
Straight answers
We tell you what a system will cost, what it saves, and what could go wrong, before you commit.
Buildable designs
Field experience runs through our team, from Master Electrician to BCIN. Our drawings are made to be built.
Long relationships
Many of our clients come back project after project. We earn that by being responsive long after the drawings are issued.
