Have you ever stood on a Construction site and wondered who makes it possible to build on hard rock? If you’re drawn to precision work, big machines, and the science of controlled explosions, a career as a Driller and Blaster in deep foundation preparation across Ontario might be for you. In this role, you help create safe, stable foundations for bridges, transit lines, high-rises, and wind turbines—even when the ground is solid rock.

Job Description
As a Driller and Blaster, you prepare rocky terrain so deep foundations—such as caissons, rock sockets, piles, anchors, and shafts—can be built safely and on schedule. You use heavy drilling equipment to cut through rock and, when required, design and carry out controlled blasts to fracture rock in a precise, low-vibration way. Your work is common on large civil projects, tight urban infill sites, and remote infrastructure jobs across Ontario.

You work under Ontario’s Occupational Health and Safety Act (OHSA) and Construction Projects regulation, and you must follow strict safety rules, environmental guidelines, and vibration/noise limits. When Explosives are used, Ontario requires a valid Blaster’s Certificate of Qualification (from the Ministry of Labour, Immigration, Training and Skills Development—MLITSD) and Compliance with federal explosives regulations.

Daily work activities

  • Review plans, geotechnical reports, job hazards, and blast designs with your supervisor or engineer.
  • Set up drill rigs and Support equipment; verify Underground utilities with Ontario One Call locates.
  • Drill boreholes for piles, caissons, tiebacks, and blast holes; install casings and manage drill fluids.
  • Load blast holes with explosive products (only certified blasters), place initiators, and protect the site.
  • Run test blasts, monitor vibrations with seismographs, and adjust the blast plan to meet limits.
  • Break, muck, and dispose of rock; coordinate with crane, Concrete, and Rebar crews.
  • Complete daily safety inspections, toolbox talks, and logbooks.
  • Maintain and troubleshoot drill rigs, compressors, pumps, and small tools.
  • Work closely with engineers, inspectors, municipal officials, and nearby property owners.

Main tasks

  • Operate and position rotary, down-the-hole (DTH), and percussion drills.
  • Read and interpret drawings, profiles, and blast layouts.
  • Prepare blast plans and charge calculations under Ontario requirements (certified blaster).
  • Install, test, and tension rock anchors and tiebacks.
  • Set up containment for noise, dust, and fly-rock control (mats, screens, barriers).
  • Take core samples, measure rock quality, and adjust drilling techniques.
  • Use seismographs to monitor and record ground vibrations.
  • Apply grout, tremie concrete, and rock-socket Cleaning methods.
  • Keep accurate records: hole depths, charge weights, delay timing, vibration readings, and as-builts.

FAQ

Do I need a Blaster’s Certificate of Qualification to work on a blasting crew in Ontario?

To handle, load, or detonate explosives in Ontario, you must hold a valid Blaster’s Certificate of Qualification issued by MLITSD. Helpers can work under Supervision on non-explosive tasks (e.g., mat placement, site prep), but they cannot load or fire blasts. Details: https://www.ontario.ca/page/blasters-certification

Who handles permits and storage for explosives on Ontario construction projects?

Your employer (the blasting contractor) is responsible for federal explosives licences and permits (storage magazines, purchase, transport) through Natural Resources Canada’s Explosives Regulatory Division. You will also need municipal blasting permits (e.g., Toronto or Ottawa) before work starts. Links:

What safety training should I complete before starting on a drilling/blasting crew?

At minimum: WHMIS, Working at Heights (if you’ll be near edges or on Formwork), First Aid/CPR, and site-specific orientations. Many employers also ask for Transportation of Dangerous Goods (TDG) awareness, Elevating Work Platform (EWP), and Traffic Control if you’re on road jobs. IHSA is a trusted source for these courses: https://www.ihsa.ca/

How do I get into urban blasting and vibration control work?

Start with a drilling or blasting program (e.g., Fleming College), join a contractor with urban projects, and build experience with seismograph setup, vibration monitoring, and blast matting. Many employers will mentor you toward MLITSD blaster certification. Learning to read and apply municipal vibration limits and doing pre-blast condition surveys will set you apart.

Will I need a commercial driver’s licence (DZ/AZ) to advance?

It’s not mandatory for all roles, but having a DZ or AZ licence makes you more employable. Crews often need to move compressors, fuel, water trucks, and equipment. If your employer transports explosives, they must meet federal requirements and provide special training—your driving licence plus TDG knowledge can open better-paid positions.

Writing Rules

Key takeaways for you:

  • Get core safety training early and pursue a college credential in drilling or blasting.
  • Aim for the Blaster’s Certificate of Qualification if you want to handle explosives.
  • Join reputable contractors or union training centres (IUOE Local 793/OETIO, LiUNA) to access major Ontario projects.
  • Build skills in seismograph monitoring, grouting, and anchor systems to stand out in deep foundation work.
  • Keep accurate logs; documentation matters as much as drilling precision in Ontario’s regulated environment.
