Ontario electrical engineering

Clear answers and drawings for your electrical project.

Calculations, drawings, and practical analysis for existing buildings, renovations, equipment changes, and focused projects in Ontario.

Engineering, not installation

Power & Plans does not perform electrical installation. Clients separately engage an appropriately authorized person or contractor. Where Ontario law requires a licensed electrical contractor, that contractor must hold the appropriate ECRA/ESA licence.

What we do

Right-sized deliverables for the work ahead.

Exact scope depends on the property, available records, observed conditions, jurisdictional requirements, and how the documents will be used.

01

Load & capacity calculations

Existing and proposed load assessment, service or panel capacity questions, feeder and transformer sizing, and option comparison.

02

Drawings & schedules

Single-line diagrams, panel schedules, layouts, control-diagram updates, and existing-condition documentation where appropriate.

03

Upgrade & equipment planning

Engineering input for renovations, additions, equipment changes, service changes, backup power, EV loads, and facility improvements.

04

Technical scopes & specifications

Defined requirements to support pricing, procurement, contractor coordination, and implementation.

05

Existing-system analysis

Review of available records and observed conditions to identify constraints, information gaps, options, and next steps.

06

Lifecycle & option analysis

Comparison of technical fit, cost implications, maintainability, operating impact, and implementation constraints.

For contractors

Engineering support that fits the construction workflow.

Defined packages for calculations, drawings, technical scopes, questions, and project coordination.

  • Load calculations and distribution-system documentation
  • Single-line diagrams, schedules, layouts, and details
  • Design information for pricing and implementation
  • Responses to defined technical questions and project changes
  • Clear separation between engineering and installation responsibility
For owners & operators

Understand the system before committing to the work.

Clarify capacity, constraints, and options before requesting contractor pricing or purchasing equipment.

  • Electrical capacity and planned-load questions
  • Upgrade option and lifecycle comparisons
  • Incomplete or outdated electrical records
  • Equipment and facility-change planning
  • Technical scopes for competitive contractor pricing
For homeowners

Plain-language engineering for major home projects.

When a renovation or new load needs more than an installation quote, receive a defined answer, useful documents, and clear responsibilities.

  • Renovations, additions, and secondary-suite planning
  • Service and panel capacity for proposed loads
  • EV charging, backup power, and major equipment additions
  • Contractor-ready drawings or engineering information where required
  • Coordination with a separately retained, appropriately licensed contractor
Typical deliverables

Documents you can put straight to work.

A typical package identifies the project, design basis, assumptions, calculations, drawings, limitations, and coordination items appropriate to its scope.

  • Engineering calculation package
  • Single-line or riser diagram
  • Panel and equipment schedules
  • Electrical layout or detail package
  • Technical memorandum or options report
  • Scope of work or equipment specification
  • Existing-condition drawings
  • Implementation and coordination notes
