Introduction

Metal fabrication businesses in Toronto and Hamilton operate in Ontario’s busiest manufacturing corridor, with risks spanning premises liability, finished‑product defects, equipment damage, and supply‑chain disruption. This page summarizes a proven coverage bundle for metal fabricators and job shops in these cities, how Summit approaches certificates of insurance (COIs) and contracts, and what underwriters evaluate locally. For broader manufacturing context, see Summit’s dedicated Manufacturing Insurance guidance, plus community specifics for Toronto and Hamilton.

FAQs

Do I need Manufacturers E&O if I only build to customer drawings?
Often yes. If you contribute to manufacturability, tolerances, or programming that could cause a client’s financial loss without bodily injury/property damage, E&O can fill the gap left by CGL/Product Liability. See Manufacturing Insurance.
What limit do Toronto/Hamilton GCs usually ask for on CGL?
Requirements vary by project. Many contracts request $2–$5M per occurrence plus additional insured and waiver wording. Your Summit broker will align terms to each contract. See CGL Insurance.
How should I think about business interruption indemnity periods?
Model realistic rebuild/lead times for custom machinery and supply chain dependencies; many manufacturers consider 12–24 months. See Business Interruption.
We deliver across the GTA—do we need cargo/inland marine?
If you transport raw material or finished goods, cargo/inland marine can cover goods in transit or at third‑party processors—often excluded from standard property forms. See Manufacturing Insurance.
Can Summit help if a landlord or customer rejects my COI?
Yes. We review the contract, explain insurer constraints, and negotiate acceptable wording/alternatives. For issues that escalate to a claim, see Claim Services.
