Ontario Electrical Estimating

Ontario Electrical Estimating Services

MeTiger provides electrical estimating and takeoff support for contractors and general contractors working across Ontario — from the Greater Toronto Area to Ottawa, Hamilton, London, Kitchener-Waterloo, and Windsor. We turn your tender drawings, specifications, and addenda into clean quantities, labour summaries, marked-up plans, and documented scope, all delivered remotely so a job’s location in the province never slows the bid.

Local context

Electrical estimating built for Ontario projects

Ontario electrical work is inspected by the Electrical Safety Authority (ESA), and installations follow the Ontario Electrical Safety Code (OESC) — the Canadian Electrical Code, CSA C22.1, adopted with Ontario amendments. We estimate to what the tender documents call for and keep that provincial context in view while we count.

Projects across the province also touch different local distribution utilities, and service, metering, and utility-coordination notes can differ between them. We account for the servicing details shown on your drawings whether the work sits in Hydro One, Toronto Hydro, Alectra Utilities, Hydro Ottawa, or Elexicon Energy territory, and we flag where the documents leave the utility interface unclear so it can be resolved before bid day.

Code & compliance

Ontario code & compliance

Our estimating and scope review are informed by the Ontario Electrical Safety Code (OESC) — the Canadian Electrical Code, CSA C22.1, adopted with Ontario amendments — alongside the project specifications, drawings, addenda, and local utility requirements. We estimate what the documents describe and note where they conflict or leave a gap, so nothing is priced on a silent assumption.

Final compliance remains subject to the project engineer, the Ontario authority having jurisdiction — including the Electrical Safety Authority (ESA) — and applicable provincial requirements. MeTiger provides estimating and coordination support only. We do not produce stamped drawings, sealed or professional engineering, or code-compliance certification, and we work alongside the engineer of record where required.

Receive a quote

A fee and delivery window, quoted after drawing review, before any work begins.

Takeoff and scope review

We perform the takeoff and organize the electrical scope by system.

Deliver the package

You receive the reviewable estimate package, with an optional walkthrough call before submission.

FAQ

Ontario estimating FAQ

Do you provide electrical estimating across Ontario?

Yes. We support electrical contractors and general contractors across Ontario remotely — the Greater Toronto Area, Ottawa, Mississauga, Brampton, Hamilton, London, Kitchener-Waterloo, Windsor, and smaller centres in between. Everything is delivered from your PDF or DWG tender set, so location on a job never limits who we can help.

Which electrical code do you estimate to in Ontario?

Our takeoffs and scope review are informed by the Ontario Electrical Safety Code (OESC) — the Canadian Electrical Code, CSA C22.1, with Ontario amendments — together with the project specifications, drawings, addenda, and local utility requirements. Final compliance remains subject to the project engineer, the Ontario authority having jurisdiction, and applicable provincial requirements.

Can you work from PDF or DWG drawings?

Both. Send a PDF tender set or DWG / CAD files, the specifications, and any addenda — or share a Dropbox, Drive, or Procore link. We work from whatever the design team issued.

How does remote delivery work for an Ontario contractor?

You upload the bid set and confirm the due date; we confirm scope, fee, and a delivery window before starting, then return a reviewable estimate package on the agreed date. No site visit is required for a takeoff, so distance across the province is not a factor.

Do you sign an NDA before we share drawings?

Yes. A non-disclosure agreement is available on request before you share any tender documents or plan links.
