Buildoreno is an Ontario-registered residential contractor, fully insured with $2M commercial general liability coverage, extended per project for larger scopes, and WSIB-covered for every worker on every project. Every structural project (underpinning, additions, second-storey) is engineer-supervised with stamped drawings from a licensed Ontario structural engineer. Building permits are pulled in every GTA municipality where we work — Toronto, Mississauga, Brampton, Vaughan, Markham, Oakville, Burlington, Hamilton, and surrounding cities. We provide proof of our registration, insurance and WSIB coverage on request before any contract is signed.

Ontario Business Registration & Code Compliance
Registered Ontario corporation operating in compliance with the Ontario Building Code across the province.
Ontario does not have a single province-wide contractor's licence for general residential work, but contractors who pull building permits, perform structural work, and run a registered business must comply with the Construction Lien Act, Ontario Building Code (O. Reg. 332/12), and Workplace Safety and Insurance Act. Buildoreno is registered as a corporation in Ontario, maintains a current Master Business License, and complies with all provincial requirements for residential construction businesses. We can provide our corporation number and tax registration on request.
Proof documentation
Business registration documents and corporation profile available on request.
Commercial General Liability Insurance — $2M
$2 million in liability coverage for property damage and bodily injury, with project-specific coverage confirmed before larger work begins.
We carry $2,000,000 in commercial general liability insurance through a major Canadian insurer. This protects you, your property, and your neighbours' property from damage during construction — accidental impacts to plumbing or electrical, water damage from a roof tear-off, fire risk during welding or torch work, and bodily injury risks on or off your property. For larger or specialised scopes, we clear the project with our insurer before work begins and coverage is extended for that specific job, so you are never relying on a general policy to cover work it was not written for. A certificate of insurance is provided to every client before contract signing, and we can supply written confirmation of project-specific coverage on request.
Proof documentation
Certificate of Insurance (COI) provided on every project, naming you as additional insured if requested.
BBB Accredited Business
Accredited by the Better Business Bureau — our business record and complaint history are public and independently reviewed.
To be accredited, a business has to commit to the Better Business Bureau's Standards for Trust — honest advertising, transparent terms, responding to complaints, and honouring commitments — and keep meeting them to stay accredited. The BBB seal on our site links straight to our BBB profile, where you can see our accreditation and any customer complaints and how we resolved them, before you ever call us.

WSIB (Workplace Safety and Insurance Board) Coverage
Every worker is WSIB-covered for workplace injury — protects you from liability.
WSIB (Workplace Safety and Insurance Board) is Ontario's mandatory workplace injury insurance system. Every Buildoreno employee and every subcontractor we engage is covered under WSIB. This is critical for homeowners: if a contractor without WSIB coverage is injured on your property, you can be held personally liable for medical costs, lost wages, and permanent disability claims — potentially hundreds of thousands of dollars. Always demand a WSIB Clearance Certificate before letting any contractor on your property. Buildoreno provides current WSIB Clearance Certificates with every contract.
Proof documentation
Current WSIB Clearance Certificate (CAD format) provided before any work begins.
Engineer-Supervised Structural Work
All underpinning, additions, and structural work is designed by licensed Ontario structural engineers.
For any work that alters a building's structural system — underpinning, bench footing, foundation repair, second-storey additions, load-bearing wall removal, structural beam installation — we engage licensed Ontario Professional Engineers (P.Eng.) to design, stamp drawings, and supervise execution. The engineer's stamp is required by every GTA municipality for building permit issuance and is critical for resale value, home insurance coverage, and structural warranty validity. The engineer remains your point of contact for any structural questions after the project closes.
Proof documentation
Stamped engineering drawings provided as part of every structural project. Engineering firm contact information provided.
Building Permits Pulled in Every Municipality
We pull and close permits in Toronto, Mississauga, Brampton, Vaughan, Markham, and every GTA municipality where we work.
Working without a permit is illegal under the Ontario Building Code, voids your home insurance, and creates major problems at resale. Buildoreno pulls building permits for every project requiring one — roofing replacements (in some municipalities), structural alterations, additions, basement apartments, and underpinning. We submit the permit application, coordinate municipal inspections at each required stage, and obtain final permit closure documentation that we provide to you for your records. The permit number, inspection records, and close-out are critical documentation for your home's future resale.
Proof documentation
Permit application, permit number, inspection records, and final closure documentation provided for every permitted project.
Installed to Manufacturer Specification — Metal Roofing
Every metal roof is installed to the manufacturer's published specification, which is what keeps their material warranty valid.
A metal roofing material warranty is conditional on installation: fastener type and spacing, expansion allowances on long panels, underlayment, valley and penetration flashing, and edge metal all have to follow the manufacturer's published specification, or the manufacturer can decline a claim. Buildoreno installs to those specifications on every metal roof, which is what protects the material warranty (typically 30–50 years) alongside our own 10-year workmanship warranty. We do not hold manufacturer installer certifications, and we do not claim to — the warranty protection comes from installing to spec, not from a badge.
Proof documentation
Manufacturer warranty registered in your name at project completion, plus our written 10-year workmanship warranty.

Frequently asked questions about our credentials
Before signing any contract, request three documents from us: (1) Certificate of Insurance from our insurer naming the policy limits and effective dates, (2) WSIB Clearance Certificate showing our current standing with the Workplace Safety and Insurance Board, and (3) Our corporation profile from the Ontario business registry. We provide all three by email within one business day of request, and we encourage you to call our insurance broker and WSIB directly to verify authenticity. Any contractor who refuses to provide these documents — or who claims they're 'not needed' — should be disqualified immediately.
Residential construction involves real risks: water damage during a roof tear-off, fire risk during torch-down installation, accidental damage to plumbing or electrical, debris striking neighbouring property, and worker injuries. If your contractor is not properly insured, you can be held personally liable for damages — and your home insurance may not cover claims arising from uninsured contractor work. With Buildoreno's coverage, any damages during construction are covered by our policy, not yours. We name you as additional insured on the policy on request for added protection.
WSIB (Workplace Safety and Insurance Board) is Ontario's mandatory workplace injury insurance for construction workers. If a worker without WSIB coverage is injured on your property, you can be held personally liable for medical costs, lost wages, and permanent disability claims — easily $100,000+ for a serious injury. WSIB Clearance Certificates are free to obtain (contractors request them through the WSIB online portal) and show whether a contractor is in good standing. Demand one before any work begins. Buildoreno provides current certificates with every contract automatically.
Almost any structural alteration, addition, basement apartment conversion, or major renovation requires a building permit. For roofing, requirements vary by municipality — Toronto generally does not require permits for re-roofing (same material), but most other GTA cities require permits for any roof replacement. Buildoreno handles the entire permit process: assessment of permit requirements, application submission, coordination of municipal inspections at each stage, and final permit closure. The permit fee is itemized in your quote. We never recommend skipping a permit — it voids insurance, creates resale problems, and can trigger retroactive permit orders at significant cost.
Buildoreno offers 5–10 year workmanship warranties depending on the service category. Roofing carries a 10-year workmanship warranty plus the manufacturer's material warranty (transferred to you in writing). Underpinning carries a 10-year structural warranty backed by the supervising engineer. Landscaping carries a 5-year hardscape warranty. If anything fails during the warranty period due to our workmanship, we return and fix it at no cost. We've been operating for 25+ years specifically because we answer the phone after the cheque clears.
Honestly, yes — and we would rather you hear it from us. We do not hold manufacturer installer certifications, ICPI paver certification, or ISA arborist certification. Where those matter we work to the published standard instead (manufacturer install specs, ICPI base and compaction standards) and we engage a qualified arborist for the reports the City requires on protected trees. We are also not Master Electricians or licensed Plumbers or HVAC technicians. For projects requiring those trades, we engage licensed subcontractors with their own ESA (Electrical Safety Authority) and TSSA (gas/plumbing) certifications, and we coordinate the relevant inspections. We are also not a registered Tarion builder — Tarion registration is required for new home construction (new builds), not for renovations or additions to existing homes. If your project requires new home construction, you need a Tarion-registered builder.
