Have you ever watched crews slice through a Concrete wall with millimetre precision and wondered, “Who does that, and how do they learn it?” If you like hands-on work, powerful tools, and solving tricky problems on active job sites, becoming a Concrete Sawyer in Ontario could be a strong fit for you.

Job Description

Concrete sawyers specialize in cutting and coring existing concrete and Masonry in buildings, bridges, roads, and infrastructure. You’ll be called when owners, contractors, and engineers need exact openings for doors, windows, mechanical/Electrical penetrations, structural modifications, or selective Demolition. The work ranges from small interior cores in hospitals to large structural cuts on high-rise retrofits or bridge deck replacements.

You’ll operate handheld cut-off saws, slab saws (walk-behind), wall saws (track-mounted), wire saws, and core drills, often with water for dust control. You’ll plan cuts, measure carefully, manage slurry (wet cutting byproduct), and protect people and property around you. Safety is central: Ontario job sites have strict rules for working at heights, exposure to silica dust and noise, and handling powered equipment.

Daily work activities

  • Review site drawings and instructions with your foreperson or client.
  • Lay out cut lines and core locations using tape measures, lasers, and anchors for track systems.
  • Set up saws, core rigs, water supply, power (electric/hydraulic), and slurry collection systems.
  • Coordinate utility locates and scanning where needed to avoid pipes, conduits, and Rebar patterns.
  • Perform cuts/cores to specifications, making adjustments for reinforcement, embedded Steel, and access.
  • Control dust, silica, noise, and water to protect the public and your crew.
  • Patch, cap, or secure openings; clean up the area and manage waste/slurry in line with local rules.
  • Complete job logs, timesheets, and tool inspections; report hazards or incidents.

Main tasks

  • Cut slabs, walls, beams, and stairs with wall saws, slab saws, and wire saws.
  • Core drill openings for Plumbing, HVAC, electrical, and anchoring.
  • Scan concrete (GPR) and mark steel/embedded services before cutting.
  • Install track systems and anchors for precision wall sawing.
  • Set up barricades, signage, and hoarding per Traffic Control requirements (Book 7, where applicable).
  • Mix and apply patching or grouting materials after coring.
  • Maintain saws, blades, bits, hydraulic units, and vacuum and water systems.
  • Follow Ontario safety regulations, including hazard assessments and PPE use.

Required Education

Concrete sawing is primarily a skills-based trade in Ontario. There is no compulsory trade licence specifically for concrete sawyers, but employers and clients expect proof of Training and a strong safety record.

    • Industry/vendor certificates (e.g., CSDA—Concrete Sawing & Drilling Association operator courses, manufacturer training from Husqvarna/Hilti).
  • College Diploma:
    • 1–2-year diplomas such as Construction Engineering Technician, Building Renovation, or Civil Technician are helpful if you want to move into Supervision/estimating.
  • Bachelor’s Degree:
    • Not required for entry. A B.Eng. (Civil) or Bachelor in Construction Management/Health & Safety can open doors to Project Management, safety specialist, or estimator roles.

Working conditions

  • Environment: indoor and outdoor sites, from tight mechanical rooms to open bridge decks.

Expert Opinion

If you’re starting in Ontario, you can become employable quickly by combining a high school diploma (or equivalent) with targeted safety training and a willingness to learn. Employers value candidates who arrive with Working at Heights, WHMIS, and First Aid/CPR already completed. Add silica awareness, MEWP, and confined space awareness, and you’ll stand out. A valid driver’s licence and a clean abstract help your resume move to the top.

A practical pathway I recommend:

  1. First 0–2 months: Complete Working at Heights, WHMIS, First Aid/CPR, silica awareness (IHSA). Learn the basics of concrete cutting from videos and manufacturer manuals (Husqvarna/Hilti). Secure your PPE kit and show up ready.
  2. Months 3–6: Get hired as a helper. Master hose/cable management, slurry control, tool inspections, and core drilling up to 4–6 inches. Shadow operators on slab saws and wall saw setups.
  3. Months 6–18: Take on small slab saw jobs, grow to wall saw setups, and get exposure to GPR scanning. Ask to attend vendor or CSDA training where possible. Build a track record for being safe, clean, and fast.
  4. Year 2+: Pursue advanced tasks—wire sawing, deep coring, tight timeline work in hospitals/food plants. Consider college courses or micro-credentials in blueprint reading, estimating, or safety to unlock lead roles.

For many in Ontario, joining a LiUNA local and training centre is an efficient route to steady, structured training and benefits. If you prefer the non-union path, target reputable cutting contractors that invest in their people and equipment, and ask about training plans from day one. Whichever path you choose, keep your certifications current, protect your hearing and lungs, and learn the craft from experienced operators—this is a trade where mentorship accelerates your progress.

FAQ

Do I need a trade licence to operate concrete saws in Ontario?

No specific compulsory trade licence exists for concrete sawing. However, you must comply with Ontario safety regulations and training requirements for the tasks you perform. At minimum, employers expect Working at Heights (if you’ll be exposed to fall hazards), WHMIS, and First Aid/CPR. Many sites (especially ICI) also require silica awareness, MEWP, confined space awareness, and site-specific orientations. See IHSA for recognized training: https://www.ihsa.ca

Is GPR scanning mandatory before coring or cutting?

It’s not a universal legal requirement, but on most professional ICI projects in Ontario, GPR scanning and/or x-ray scanning is a standard risk control, especially for structural elements, post-tensioned slabs, hospitals, and data centres. Many clients will not allow coring or cutting without documented scanning and sign-off. Coordinating with Ontario One Call is mandatory before digging and good practice when cuts could affect underground services: https://ontarioonecall.ca

How is concrete slurry handled legally in Ontario?

You cannot discharge slurry into storm drains and many municipalities restrict sanitary discharge due to pH and solids. Best practice is to vacuum, filter/solidify, and dispose through approved waste streams. Always follow the local by-law in your job’s municipality. For example, Toronto’s Sewer Use By-law guidance is here: https://www.toronto.ca/services-payments/water-environment/sewers-and-stormwater/sewer-use-by-law/

Will a DZ licence help my career as a concrete sawyer?

A G-class licence is typically required. A DZ licence is not mandatory for most operator roles but can make you more valuable if your employer runs vacuum trucks, larger service vehicles, or equipment transport. It can also position you for lead roles that involve logistics and mobilization across multiple sites.

How do I move from operator to estimator or foreperson in Ontario?

Build depth on complex systems (wall/wire sawing), learn blueprint reading, and start tracking labour, blades/bits, and mobilization times to understand costs. Adding a college diploma in construction or a health and safety certificate can help. Ask your employer for exposure to site meetings and quoting. Consider micro-credentials through Ontario colleges or vendor training. Keep your safety record spotless—lead roles often require planning work in high-risk environments under O. Reg. 213/91: https://www.ontario.ca/laws/regulation/910213

Writing Rules

  • Be thorough and precise: your safety training, situational awareness, and equipment knowledge are as important as your cutting technique.
  • Keep your Ontario certificates current and recognized by the Chief Prevention Officer (CPO) where applicable (e.g., Working at Heights): https://www.ontario.ca/page/working-heights
  • Build a portfolio: photos of clean setups, accurate cuts/cores, and client references help you advance.
  • Network where the work is: monitor Ontario procurement and project news (e.g., Infrastructure Ontario), and connect with reputable contractors and LiUNA training centres.
  • Protect your health: prioritize silica and noise controls. Use water, HEPA vacuums, respirators (P100), and quality hearing protection consistently.
