What Is On-Site Welding?
On-site welding — also called field welding or portable welding — means a fully equipped welder travels to your location and completes the work in place. No dismantling, no loading, no trucking to a fabrication shop and back. The work gets done exactly where it needs to be, on the schedule you need it done.
For most commercial, industrial, and large residential welding jobs in Toronto, field welding isn’t just convenient — it’s the only practical choice. Structural steel in an active building can’t be removed. Equipment frames are bolted to floors. Gates are set in concrete. Structural columns are welded into place. When the metal can’t come to a welder, a welder must come to the metal.
CanaWelding is a division of CanaStruct — a structural framing and building company operating across Ontario. Our welders bring builder-level understanding to every job. They assess structural loads, anticipate connection requirements, and identify issues beyond the visible repair point.

On-Site Field Welding vs. Shop Drop-Off
Why Mobile Welding Wins for Most GTA Jobs
Most welding shops require you to remove the item, load it, drive it in, and wait for a repair slot. That works for small, transportable parts. It doesn’t work for a gate post set in concrete, a railing bolted to a building, a trailer in your yard, or structural steel in an active build. For those jobs, the shop option doesn’t exist — mobile welding is the only option.
Factor in transport costs, disassembly labour, and production downtime, and field welding almost always costs less than the shop alternative for most GTA applications. It’s not a premium upgrade. It’s the efficient, practical choice. Welding in context also means exact fit — no tolerance gaps from transport or re-positioning, no thermal distortion from moving a warm assembly.
When a Shop Is the Right Call
Shop work makes sense when a component requires bench fixturing or machining that can’t be replicated in the field, when the repair needs post-weld heat treatment in a controlled environment, or when the part is small, easily transported, and non-integrated. For precision TIG work on thin-wall stainless or complex custom fabrication requiring fixtures, a shop environment improves the result.
When you call us, we’ll tell you honestly which approach is right for your specific job. If it’s better done in a shop, we’ll say so. If it can be completed on-site — and for most welding repair and installation calls in the GTA, it can — we’ll confirm same-day availability and come to you.

Frequently Asked Questions
What is the difference between on-site welding and shop welding?
On-site (field) welding means the welder travels to your location and completes the work in place — no transport, no disassembly. Shop welding requires you to bring the material to a fixed facility and wait for a slot. On-site is the right choice when the structure is too large or integrated to move, when disassembly would cause significant downtime, or when the job is part of an active construction sequence. For most welding calls across the GTA, field welding is faster, cheaper, and more practical.
Is on-site welding safe and certified?
Yes — completely. Our welders hold CWB (Canadian Welding Bureau) certification under CSA W47.1, the national standard for structural welding quality in Canada. We carry full commercial general liability insurance and maintain active WSIB clearance. Safety data sheets, insurance certificates, and CWB documentation are available in advance of any site visit. General contractors, HSE coordinators, and site supervisors can approve us without delay.
What welding processes do you offer on-site?
We perform MIG (GMAW), TIG (GTAW), and Stick (SMAW) welding on-site, selecting the appropriate process for the material, position, and environment. On-site structural steel welding uses FCAW or SMAW for wind tolerance in open sites; TIG is used for aluminum and stainless; MIG handles most mild and structural steel repair work. If you’re not sure which process your job requires, describe the material and application when you contact us and we’ll advise.
How much does on-site welding cost in Toronto?
Cost depends on job complexity, material type, site access conditions, and time required. Most standard service calls — repairs, railing installs, small structural work — range from $150 to $400. Larger commercial and industrial jobs are quoted on-site after assessment. We always provide a complete, itemized quote before any work begins. What we quote is what you pay — no material surcharges, no travel fees added after the fact.
How quickly can you get a welder to my site?
For standard booked jobs, we typically schedule within 1–3 business days across the GTA. For urgent or time-critical needs, call us directly at (647) 641-0550 rather than submitting a form — phone gets you a faster response. We give you an honest estimated arrival time when you call and we hold to it. Response time depends on current schedule and your location, but we don’t give four-hour windows and disappear.
Can you work on active construction sites?
Yes — active construction sites are a core part of our work, not an exception. We coordinate directly with general contractors and site managers, provide required documentation ahead of time, and integrate cleanly into live construction schedules. Our background in structural framing at CanaStruct means we understand construction sequencing — we know when in the build welding occurs, how our work connects to other trades, and how to operate on an active site without disrupting the schedule.
What materials can you weld on-site?
We weld mild steel, structural steel, stainless steel, aluminum, and wrought iron on-site. Material selection drives our process choice — TIG for aluminum and stainless, MIG for structural and mild steel, Stick for outdoor and vertical structural work. If your job involves an unusual alloy or material combination, describe it in your inquiry and we’ll confirm capability before booking.
