FAQ

Do I need a college diploma to become a diamond or longhole driller in Ontario?

No, you do not strictly need a diploma. Many drillers enter the field with OSSD (high school), complete the required Common Core training (and site orientations), and learn on the job. However, a college diploma—especially Fleming College’s Resources Drilling Technician—can help you get hired faster, advance more quickly, and qualify for a wider range of roles in drilling and geotechnical services.

What certifications are mandatory before I can work on a drill?

Ontario mines require workers to complete role-specific Common Core training and site orientations. For exploration (surface) roles, employers often require the Surface Miner or Surface Diamond Driller Assistant Common Core. For underground roles, you will need Underground Hard Rock Miner Common Core, plus specialty modules for longhole drilling. You will also need WHMIS, Standard First Aid & CPR, and any site-required safety training (for example, fall protection and respirator fit testing). Training is typically delivered by approved providers such as NORCAT and Workplace Safety North.

What is the difference in day-to-day work between diamond drilling and longhole drilling?

  • Diamond drilling (exploration) is about core recovery and geological information. You’ll set up surface or underground diamond drills, use drilling fluids, and handle core carefully for geologists. You may work in remote camp settings and move between drill pads often.
  • Longhole drilling (production) is all about precision and production. You’ll drill deep, accurately aligned holes in underground stopes according to engineering plans. Your work prepares the orebody for blasting. You’ll work closely with survey, blasting, and production teams in an underground environment with established services and schedules.

Where are most driller jobs located in Ontario, and will I need to travel?

Most jobs are in Ontario’s mining belts: Greater Sudbury (nickel, copper, PGMs), Timmins and Kirkland Lake (gold), Red Lake (gold), Marathon area (critical minerals), and other Northern communities. Travel is common. For exploration drilling, fly-in/fly-out or drive-in remote camps are typical; for underground longhole roles, you may commute locally if you live in a mining community or follow a rotation schedule with provided accommodation.

How do bonuses and pay premiums work for drillers?

Pay structures vary by employer and union status, but many Ontario drillers receive:

  • Overtime after 8 or 10 hours per day, or after 44 hours per week (employer policy or union agreement applies).
  • Shift premiums for nights or weekends.
  • Production or meter bonuses (more common in exploration drilling).
  • Remote or Northern allowances and per diems for camp work.
  • Benefits and pension plans are common at larger employers and unionized sites.
