Local Business Spotlight: McLellan Vitella Engineering Ltd.

One of the top firms we recommend is McLellan Vitella Engineering Ltd. With over 90 years of combined experience, they’ve built a reputation for delivering complete mechanical and electrical engineering solutions for multi-unit residential, commercial, institutional, and industrial projects.

Their team of professional engineers and senior designers takes pride in designing systems that are both functional and efficient. They understand the real-world challenges contractors face during construction, and they tailor their designs to minimize those issues while still meeting the highest standards for safety and compliance.

Over the years, they’ve worked with a wide range of clients, from national brands like U-Haul and Pet Valu to public sector organizations such as Huron County. They also collaborate with local contractors and architects who value precision, reliability, and on-time delivery.

When you work with McLellan Vitella Engineering Ltd., you’re choosing a firm that understands Southwestern Ontario’s building codes, climate considerations, and industry demands. That local knowledge can be the difference between a smooth project and one that’s slowed down by costly design changes.

HVAC System Design & Mechanical Engineering

Heating, ventilation, and air conditioning systems are among the most important components of any building’s infrastructure. The engineers we connect you with design HVAC systems that balance comfort, air quality, and energy efficiency.

In commercial and institutional buildings, a well-designed HVAC system doesn’t just keep people comfortable — it can significantly reduce operating costs. Our recommended partners take the time to understand your building’s purpose, occupancy patterns, and operational needs before designing a system that meets those requirements without overspending on capacity.

For older buildings, retrofitting HVAC systems can be a challenge. Our partners handle upgrades that improve efficiency while respecting the existing structure and minimizing downtime. Whether it’s a new installation or a complete system overhaul, you can trust that the design will be practical, efficient, and built to last.

Plumbing System Design & Engineering

Plumbing design isn’t just about running pipes — it’s about creating a system that will deliver reliable water supply and drainage for decades. The engineers we recommend approach plumbing design with both function and long-term performance in mind.

For multi-unit residential buildings, commercial spaces, and specialized facilities like healthcare centers, plumbing systems must be designed for consistent flow, proper pressure, and minimal maintenance issues. Our partners create systems that meet those needs while complying with all applicable codes and standards.

Sanitary and storm drainage engineering is another area where expertise matters. Poorly designed drainage can lead to flooding, water damage, and costly repairs. The engineers we work with ensure your system is robust enough to handle heavy rain events and is integrated seamlessly with the rest of your building’s infrastructure.

For safety, they also design fire protection and sprinkler systems that comply with regulations and integrate into the broader building plan without creating conflicts with other systems.

Electrical Power Engineering

Electrical systems are the backbone of modern buildings, and our network includes engineers who excel at electrical power design. They plan everything from main service entry to the final outlet, ensuring safe, reliable, and efficient power distribution.

If you’re considering integrating renewable energy sources like solar or wind into your facility, our partners can design systems that tie those sources into your existing grid. They account for power storage, load balancing, and compliance with provincial regulations, ensuring your investment pays off over the long term.

Electrical code compliance is another key area. Codes evolve over time, and older systems often need upgrades to meet current standards. Our recommended engineers handle these upgrades while minimizing disruption to your operations.

Lighting Design Engineering

Lighting impacts everything from energy bills to how people experience your space. Our partners create lighting designs that enhance both functionality and aesthetics.

For interior spaces, they focus on delivering the right level of illumination for the intended use — whether it’s a bright, evenly lit retail space or a warm, welcoming reception area. They also consider how lighting can influence mood and productivity.

Outdoor and security lighting is equally important. Well-designed exterior lighting improves safety, highlights architectural features, and extends the usable hours of outdoor spaces. Energy-efficient lighting solutions, including LED and smart control systems, can further reduce operating costs without sacrificing quality.

Service Areas Across Southwestern Ontario

Through SarniaContractors.ca, you can connect with mechanical and electrical engineers who work in Windsor, St. Thomas, Hamilton, Milton, Guelph, Clinton, Exeter, Goderich, and surrounding communities.

These are markets where building projects often require a mix of local insight and technical expertise. In Windsor, engineers may need to consider unique weather and wind conditions from the Detroit River. In Hamilton, industrial retrofits might need to integrate with existing manufacturing processes. In smaller towns like Clinton or Exeter, engineers may need to design with limited infrastructure in mind.

No matter the location, we make sure you’re connected to a reliable local expert who understands the specific challenges of building in that community.

Project Types We Support

We work with engineering firms that have experience across a wide range of project types. Multi-unit residential developments require careful coordination to ensure each unit has consistent, reliable systems without overloading the infrastructure.

Commercial offices and retail spaces often have unique requirements for lighting, HVAC zoning, and electrical distribution. Institutional facilities such as schools and hospitals demand systems that can handle high occupancy, heavy use, and strict safety regulations. Light industrial projects require engineering solutions that support manufacturing processes, machinery loads, and future expansion possibilities.

By matching you with an engineer who has worked on similar projects, we help ensure your building’s systems are designed to meet the specific demands of your sector.

One Request. The Right Team.

Coordinating multiple service providers can be time-consuming and frustrating. At SarniaContractors.ca, we make it simple. Submit one project brief, and we’ll connect you with a qualified mechanical and electrical engineering firm — and if your project requires it, we’ll also introduce you to trusted contractors to bring the designs to life.

This approach saves you time, reduces miscommunication, and ensures that the engineering and construction teams are aligned from day one.
