NDT Simulator & Practical NDT Training in Ontario

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience. For Ontario, where one technician might go from a nuclear outage to a steel mill to a Sarnia refinery turnaround within a year, that practice matters. Practical NDT is an immersive, 3D, game-like platform that runs in a browser or app. You step into a virtual workplace, choose your equipment and work a real inspection job on a realistic asset, such as a weld coupon, a heat-exchanger bundle, a storage tank or an airframe component. Every job is scored as soon as you finish, and the feedback shows what you found, what you missed and where your technique went wrong. It is built for every level, from someone in their first month to an experienced Level 3 who needs to benchmark a team.

Ontario has the widest industrial NDT footprint in Canada. It has three nuclear generating stations: Bruce, Darlington and Pickering, which is now moving into refurbishment. It has Canada's first grid-scale small modular reactor under construction at Darlington, the refineries and petrochemical plants of Sarnia's Chemical Valley, integrated steelmaking in Hamilton, auto and EV battery manufacturing along the Highway 401 corridor, nickel and copper mining around Sudbury, and an aerospace sector in the Greater Toronto Area and Ottawa. Each of these asks for different methods and different habits. Practical NDT gives technicians somewhere to keep all of them sharp. To see how it fits your crew, request an Ontario demo.

Ontario's NDT workforce and where the work is

The nuclear corridor. Ontario produces most of Canada's nuclear electricity. Bruce Power's site on Lake Huron is in the middle of a long Major Component Replacement programme. East of Toronto in Durham Region, Darlington has completed a major refurbishment programme and the first BWRX-300 small modular reactor is being built there under a licence to construct issued by the Canadian Nuclear Safety Commission in April 2025. Pickering's remaining units are moving from operation into refurbishment. CANDU plants generate intense demand for eddy current on steam generator and heat-exchanger tubes, ultrasonic inspection of feeder pipes and pressure-boundary welds, and visual and surface examination under periodic inspection programmes written to CSA N285.4. Refurbishment and component replacement add large amounts of weld inspection on new and repaired components.

Southwestern Ontario. Sarnia's Chemical Valley on the St. Clair River is one of the largest concentrations of refining and petrochemical capacity in Canada. It is also a major crude and products pipeline hub linked to the US Midwest. Refinery and chemical plant turnarounds in Sarnia draw large crews for exchanger tube inspection, piping and vessel corrosion surveys, alloy verification and tank inspection. Further along the 401, Windsor, London, Kitchener-Waterloo and Cambridge build vehicles, parts, tools, dies and moulds, and now EV batteries. That work creates demand for weld inspection on production fixtures and structures, and for UT and ET on manufactured components.

The Golden Horseshoe. Hamilton is Canada's steel city, with integrated and electric-arc steelmaking, a busy port and heavy fabrication shops. The Toronto region adds aerospace component and landing-gear manufacturing, aircraft maintenance around Pearson, and a huge infrastructure programme of transit tunnels, bridges and towers that needs structural weld inspection. Niagara's hydroelectric stations and the Nanticoke industrial area add more.

Northern and eastern Ontario. Sudbury's nickel and copper mines and smelters, along with the mines of the Timmins and Red Lake districts, need inspection of hoists, headframes, crushers, mobile equipment and process vessels. Ottawa brings aerospace and defence research, including the National Research Council's aerospace facilities, and the Ottawa Valley is home to Canada's nuclear research laboratories at Chalk River. Pipelines and compressor stations run across the whole province. The result is a large, mobile workforce that has to be ready for very different jobs.

Practical NDT by city in Ontario

Every Ontario city below has its own Practical NDT page with more local detail. This table maps local work to Practical NDT environments and methods.

Toronto. The GTA mixes aerospace manufacturing, aircraft maintenance and a large infrastructure build-out, and Pickering and Darlington are nearby. Toronto technicians may do eddy current on aircraft parts one month and structural weld inspection on a transit project the next. The Aircraft Hangar and Welding Workshop environments cover both.

Sarnia. Chemical Valley turnarounds are Sarnia's defining inspection event. Crews need IRIS on exchanger tubes, PMI on alloy piping, corrosion mapping on vessels and piping, and tank floor and shell surveys. The Oil & Gas Site and Storage Tank environments were designed for exactly that mix.

Hamilton. Steel mills and heavy fabricators on Hamilton Harbour need weld inspection on thick sections, structural members and plant equipment. The Welding Workshop lets inspectors practise RT interpretation, PAUT and TOFD on thick butt welds, and MT on fillets and repairs.

Windsor. Windsor's economy runs on vehicle assembly, tool and mould making and a large new EV battery plant. Inspection here is closer to manufacturing QA than plant integrity. NDT Lab jobs build solid UT, ET and PT fundamentals, and Welding Workshop jobs cover fixture and structural welds.

Sudbury. Mining and smelting equipment takes heavy cyclic loads, so fatigue cracking at welds is the main concern. MT and UT on welded structures, shafts and wear components are everyday work. The Welding Workshop is the natural place to practise, with Oil & Gas Site jobs for process-plant thickness surveys and PMI.

Ottawa. Ottawa's inspection work leans toward aerospace research, defence and precision components, with nuclear research in the Ottawa Valley. The Aircraft Hangar environment fits eddy current and UT on airframe and engine components, and the NDT Lab covers calibration and reference-block fundamentals.

Kitchener-Waterloo. Waterloo Region combines vehicle assembly in Cambridge, parts suppliers and advanced manufacturing. Technicians here need clean fundamentals on machined and welded components, which the NDT Lab and Welding Workshop environments cover.

Environments and methods that match Ontario work

Practical NDT has five workplace environments and twelve methods, with 33 guided lessons to get newcomers started.

Oil & Gas Site (73 jobs). This is built around a process plant, so it is the best match for Sarnia and for anyone supporting refinery or chemical turnarounds. Practise IRIS on heat-exchanger and boiler tubes, PMI alloy verification, LRUT guided-wave screening on pipe runs and racks, and contact UT, PAUT and TOFD on piping and vessel welds and corrosion.

Storage Tank. Run UT shell thickness surveys and MFL floor screening on a full-size virtual tank. This fits Sarnia's tank farms, terminals and the storage that sits along Ontario's pipeline network.

Welding Workshop (52 jobs). Weld coupons and fabrication joints for RT, PAUT, TOFD, MT, PT and VT. This environment supports Hamilton's heavy fabrication, pipeline and station construction, mining equipment repair in Sudbury, and the weld-heavy work of nuclear refurbishment and component replacement. The simulator does not model CANDU-specific tooling. It does, however, build the underlying weld-inspection skills that nuclear work also depends on.

Aircraft Hangar (54 jobs). Airframe and component inspection with eddy current, UT and PT, which fits the aerospace manufacturers and maintenance organizations around Toronto and Ottawa. The eddy current practice also carries over to tube inspection habits, such as reading impedance-plane signals and separating real indications from noise.

NDT Lab (52 jobs). Bench specimens and reference blocks for calibration, probe selection, DAC and TCG set-up and basic sizing. This is where Windsor and Kitchener-Waterloo manufacturing inspectors, and every new trainee, build fundamentals.

Regulators and requirements Ontario technicians meet

Personnel certification. Canada's national NDT personnel certification scheme is CAN/CGSB-48.9712, the Canadian adoption of ISO 9712. The Canadian General Standards Board ceased operations on 1 April 2026. The standard remains valid, and certification is issued by Natural Resources Canada's NDT Certification Body, which continues to qualify and certify NDT personnel without interruption. Many Ontario employers, especially in nuclear, pressure equipment and pipelines, ask for NRCan certification. US-owned service companies and some aerospace employers also use an ASNT SNT-TC-1A written practice or NAS 410. Atlantis training works within the SNT-TC-1A framework and does not administer or grant NRCan certification. Practical NDT is practice for any scheme and does not certify anyone under any of them.

Radiography. Gamma radiography in Canada is federally regulated by the Canadian Nuclear Safety Commission. Anyone operating an exposure device must be a CNSC-certified exposure device operator (EDO) or work under the direct supervision of one, and EDO certification requires formal training and supervised on-the-job hours. Industrial X-ray equipment in Ontario falls under the provincial X-ray Safety regulation under the Occupational Health and Safety Act. Practical NDT's RT scenarios cover set-up and interpretation only. They do not count toward EDO training or hours, and they involve no real sources.

Pressure equipment and nuclear. Ontario's Technical Standards and Safety Authority (TSSA) administers boilers and pressure vessels under the Technical Standards and Safety Act, using CSA B51 and the ASME Boiler and Pressure Vessel Code. TSSA also serves as the authorized inspection agency for pressure-retaining systems at Ontario's nuclear facilities. Nuclear pressure-boundary work follows the CSA N285 series, including N285.4 periodic inspection, under CNSC licensing.

Other codes. Pipelines are built and maintained to CSA Z662. Interprovincial lines are regulated by the Canada Energy Regulator and provincially regulated lines through TSSA. Welded steel structures follow CSA W59, and fabricators are certified to CSA W47.1 through the Canadian Welding Bureau. Refineries and plants in Sarnia typically run inspection programmes built on API 510, 570 and 653 alongside provincial requirements.

For trainees, working technicians and Level IIIs in Ontario

New trainees. Ontario draws new inspectors from college NDT and welding programmes, the skilled trades, the military and newcomers to Canada who trained elsewhere. The guided fundamentals path gives every trainee the same structured start. It covers how each method works, how to calibrate and how to scan, then builds up to scored jobs with realistic defects. Trainees get plenty of repetitions before they touch a real specimen or a client's asset, which is useful preparation for the classroom training and experience hours any scheme requires.

Working technicians. Ontario work is seasonal and outage-driven. Nuclear outages, spring and fall refinery turnarounds and summer construction seasons create peaks, and in between technicians may work in a completely different sector. Skills you do not use fade. You might not have read a TOFD scan since the last pipeline job or run IRIS since the last Sarnia turnaround. Practical NDT lets you drill rare defects and less-used techniques in the weeks before a mobilization.

Level 3s and team leads. For a Level 3 managing technicians across several sites and sectors, Practical NDT offers something that is hard to get otherwise: an objective, repeatable comparison. You can build scenario sets that reflect your procedures, assign them, see who is consistently missing a defect type or leaving coverage gaps, and target refresher work before the next outage. It supports your judgment and your written practice. It does not replace either.

Practice vs certification

Practical NDT is a skills-practice and readiness tool, and nothing more. It is not a certification, and it is not a substitute for any practical examination. Whether a technician is certified through NRCan under CAN/CGSB-48.9712 or by an employer under an SNT-TC-1A written practice, the practical exam is taken on real specimens with real equipment, and the training and experience hours must be documented under that scheme's rules. A simulator cannot supply those. Practical NDT does not award hours, does not issue certificates and does not count toward CNSC exposure device operator certification.

What it does offer is readiness. Candidates who have worked through many scored scenarios arrive at a practical exam knowing what indications look like and how to set up a technique cleanly. Technicians who refresh before an outage start faster. Supervisors get a clearer picture of where each person stands. For formal NDT training, see Atlantis NDT training and certification. Treat Practical NDT as a complement to formal training and certification, never a replacement.

Bring Practical NDT to your Ontario team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience. Its scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training. An Ontario demo usually starts from your sector. For a Sarnia turnaround contractor, that means the Oil & Gas Site and Storage Tank. For a Hamilton fabricator or pipeline contractor, it means the Welding Workshop. For aerospace in Toronto or Ottawa, it means the Aircraft Hangar. For a training coordinator, the focus is the NDT Lab and guided lessons. We then look at rollout: individual logins, refresher sets timed around outages and turnarounds, and scenario assignment and benchmarking for your Level 3.

Practical NDT runs in a browser or app, so crews can practise at the shop, at home or in a hotel between shifts. Pricing is quote on request and tailored to your team.

Frequently asked questions

Is Practical NDT recognized for NRCan CAN/CGSB-48.9712 certification?

No. Practical NDT does not grant certification and does not count toward the training or experience hours NRCan's NDT Certification Body requires. It is practice that helps you prepare for the real practical exam and for field work under any scheme.

Did the CGSB closure change NDT certification in Ontario?

The Canadian General Standards Board ceased operations on 1 April 2026, but the CAN/CGSB-48.9712 standard remains valid and NRCan's NDT Certification Body continues to certify personnel. Check NRCan's own guidance for the latest details on applications and renewals.

Can I practise refinery methods for Sarnia turnarounds?

Yes. The Oil & Gas Site includes IRIS on exchanger and boiler tubes, PMI, LRUT, corrosion mapping and weld inspection with UT, PAUT, TOFD and RT, and the Storage Tank environment covers shell UT and MFL floor screening.

Does it help with nuclear work at Bruce, Darlington or Pickering?

It builds transferable weld-inspection, UT and eddy current skills. It does not simulate CANDU-specific tooling or site procedures, and nuclear work still requires the site's own qualification and training under CNSC-licensed programmes.

Does RT practice count toward CNSC exposure device operator certification?

No. EDO certification requires CNSC-recognized training and supervised on-the-job hours with real exposure devices. Practical NDT only lets you practise radiographic set-up and interpretation, with no real radiation involved.
