Electrical Engineering
MXL Engineering delivers complete electrical engineering services, from initial load calculations and service design through permitting, tendering, and on-site construction administration. We design safe, code-compliant electrical systems for residential, commercial, industrial, and institutional projects, working closely with utility providers, contractors, and authorities having jurisdiction to keep your project moving from drawing board to energization.
Design & Analysis
Load Calculations & Utility Coordination: DLoad calculations to size services, feeders and equipment, plus utility applications and coordination through to final connection.
Service Design & Upgrades: : Electrical service design for new buildings, and assessment and redesign of existing services for added capacity, renovations or changes in occupancy, including service entrance, distribution, branch circuiting and panel layouts..
Electrical Layouts: Power, receptacle, switching and lighting layouts coordinated with the building design.
Site Photometric Plans: Exterior lighting layouts and photometric studies for site plan approval.
Life Safety Systems
MXL Engineering & Associates designs the life safety systems that protect occupants and meet code, including:
Fire Alarm Design: Code-compliant fire alarm systems engineered to CAN/ULC-S524 and the Ontario Building Code, with full device layouts, riser diagrams, and verification documentation.
Emergency Lighting: Emergency lighting and exit signage design coordinated with the building layout, egress paths, and applicable code requirements.
Verification & Sign-Off: Coordination with verification contractors and authorities having jurisdiction to ensure systems are commissioned and certified for occupancy.
Permitting, Tendering & Construction
Permit Drawings: Stamped electrical drawings and specifications prepared for permitting with authority having jurisdiction.
Tender Packages: Clear, contractor-ready tender documentation that defines scope, materials, and performance standards to support competitive and accurate pricing.
Construction Administration: Ongoing support during construction, including RFI responses, submittal review, and site instructions.
Site Inspections: Periodic site reviews to confirm installations match the engineered design and meet code, culminating in final electrical sign-off.
Sectors We Serve
We provide electrical engineering services across the full range of building types: residential, commercial, industrial, and institutional, from single-family homes and multiplexes to retail, warehouses, manufacturing facilities, schools, and care facilities.
Our Projects
FAQ
Electrical engineering covers how power gets into a building and where it goes from there. We design the full system, from the utility connection and main service to panels, circuits, lighting, and outlets, so it’s safe, code-compliant, and sized for how the building will actually be used.
If you’re building or renovating a commercial, industrial, or multi-unit building, upgrading your electrical service, or changing how a space is used, most likely yes. The city or utility will often require stamped electrical drawings before issuing a permit or connecting power.
A properly engineered system is safer, code-compliant, and built for how your building will actually be used. We handle the load calculations, utility coordination, and permit drawings, so your contractor builds from a clear plan and your project stays on schedule.
An electrical engineer designs the electrical system; the electrician builds it. The engineer works out how much power the building needs, how it gets distributed, and where everything goes, then produces the stamped drawings and specs your contractor, the city, and the utility all work from.
