Yesterday, Glencore announced that the shaft at Craig Mine’s Onaping Depth Project is complete and the ore body has been reached nearly 2,600 metres underground. That is good news for Greater Sudbury. The useful question for the rest of us is: what does it actually change?
When a mining announcement this large lands in Sudbury, people naturally connect it to jobs, the local economy and real estate. They should. Mining does not stop at the mine gate here. It runs through contractors, equipment suppliers, trades, engineering, professional services and the households supported by that work.
But I also do not want to oversell it. Yesterday’s announcement did not increase the value of every home in Greater Sudbury. It did not make every rental a good investment, and it should not rush anyone into buying.
What it gives us is something more useful: clearer evidence that a major Sudbury employer is planning to operate here for a long time.
What actually happened yesterday?
On August 27, 2026, Glencore announced that the internal shaft at Onaping Depth had been completed and that workers had reached the high-grade nickel-copper ore body. The first mining areas, called stopes, have been prepared and ore can begin coming from them.
Some of the coverage called this the start of production. That is fair as long as we understand what stage the project is at. First ore begins the ramp. Full-scale operation and project completion are targeted for 2027.
Glencore and Ontario describe the investment since construction began in 2019 as nearly $2 billion. Local reporting used a $1.8-billion figure. At scale, Ontario projects one million tonnes of ore per year. The current mine plan estimates about 280 kilotonnes of nickel and 145 kilotonnes of copper over the life of the mine, with production in the Sudbury Basin extending beyond 2040.
The job numbers also need context. The project generated roughly 7,000 unique jobs during its development. That is not 7,000 new permanent positions. Once fully operational, it is expected to support approximately 400 permanent jobs.
My read: the real value in this announcement is the length of the commitment. A completed shaft, prepared stopes and access to ore are much stronger signals than a project that only exists in a proposal or news release.
This project has been taking shape for decades
Onaping Depth did not appear yesterday. The deposit was discovered more than 30 years ago, and the project has moved through feasibility, approval, shaft construction and changing cost estimates ever since.
| Period | Public milestone | Why it matters now |
|---|---|---|
| 1994 | The deposit was discovered, according to historical local reporting. | The resource story began more than 30 years before the 2026 milestone. |
| 2016 | Glencore completed the feasibility study. | The project moved from geological potential toward an engineered mine plan. |
| 2017–2018 | Development advanced, full project approval was received, and the shaft contract was announced. Reporting at the time described a US$700-million project. | Major capital and local contracting commitments became tangible. |
| 2019 | Construction began; Glencore also reported completion of a specialized underground headframe excavation. | The difficult work of building a deep mine inside existing Craig infrastructure was underway. |
| 2022–2024 | Ontario listed Onaping Depth as a $1.3-billion mine-construction project. In July 2024, Nickel Rim South entered care and maintenance after almost 15 years of production. | Onaping Depth became increasingly important to the continuity of Glencore’s Sudbury feed and operations. |
| August 2026 | The shaft was completed, the ore body was reached, and the investment since 2019 was described as nearly $2 billion by Glencore and Ontario. | The production ramp can begin, with full-scale operation targeted for 2027 and production expected beyond 2040. |
Those changing estimates matter. Ultra-deep mining is difficult, and early schedules are not the same as finished work. That is why yesterday’s physical milestone deserves attention.
How this reaches the rest of Greater Sudbury
The City identifies more than 300 mining-supply firms and over 14,000 people working in Greater Sudbury’s broader mining supply and services cluster, with approximately $4 billion in annual exports.
Glencore’s Sudbury Integrated Nickel Operations — the mine, mill and smelter — employ more than 1,000 people. The company reports that, in 2024, the operation spent more than $650 million on goods and services from Ontario suppliers and contributed nearly $400 million in direct GDP to Ontario.
Not all of that spending stays in Sudbury, and it does not all flow into housing. Still, a long-lived operating mine supports more than the people working underground:
- Permanent operating and technical employment
- Trades, maintenance and contract work
- Mining equipment, engineering and technology suppliers
- Local spending by households with stable incomes
- Confidence to train, hire, expand and remain in the region
The technology is part of the local story too. Ontario says the operation will use 66 electric vehicles and projects approximately 40 per cent less ventilation energy and 30 per cent less cooling energy than an equivalent diesel operation. Sudbury is not only supplying minerals. Local workers and companies are building experience in the technology needed to mine safely and efficiently at this depth.
So, what could this mean for housing?
The connection is not immediate, but it is fairly easy to follow. When people can see stable work ahead, they are more likely to make long-term household decisions. Suppliers can hire. Employees can relocate. Families may decide to stay instead of leaving for work elsewhere.
Over time, that can support housing demand. It does not tell us which house will sell, what a buyer should pay, or what your home is worth today.
Craig Mine is part of the northwestern mining corridor, so Onaping and Levack are obvious places to watch. But the effect will not stop at the nearest communities. Mine employees and suppliers live across Greater Sudbury, and buyers choose homes based on far more than distance to work.
How I would use this information if you are making a move
If your work is connected to the project
Start with the stability of your own position, not the total job number in the announcement. There is a real difference between construction work, contract work and a permanent operating role.
Before choosing a price range, ask your lender how it will treat overtime, bonuses, shift premiums or a recent job change. A strong income on paper does not help if the mortgage approval uses a lower qualifying amount. Build the purchase around the income you can reliably carry, not your best month.
If you are considering Onaping or Levack
Do the drive at the time you would actually be travelling. A daytime map estimate may not answer what the commute feels like before or after a long shift.
Then compare the whole property, not only the purchase price. Confirm the heating system, water and sewer setup, internet service, insurance, taxes, maintenance history and the amount of work the home needs. These details can change the monthly cost enough to erase what looked like a bargain.
You can use my current Onaping and Levack listings page to see what is actually available instead of relying on an old market snapshot.
If you are buying elsewhere in Greater Sudbury
Treat this news as one point in favour of long-term local confidence. Then come back to the property in front of you.
Does the payment leave room for repairs and normal life? Will the home still suit you if your work location changes? Are you paying for condition and location, or reacting to competition? Does the recent sales evidence support the price?
A positive economic story does not turn the wrong house into the right one.
If you are thinking about selling
Do not add a “mine announcement premium” to your asking price. Buyers still compare your home with the other homes they can purchase today.
The announcement may help the confidence behind the market, especially if employment and supplier activity grow as planned. Your pricing still needs to come from recent comparable sales, current competition, the condition of the property and how buyers respond once it is listed.
That is why my selling process starts with preparation, pricing and positioning. Economic context is helpful. It does not replace the work.
If you are considering a rental property
Do not use 7,000 project jobs as a rental-demand number. That figure covers unique jobs generated during development. The operating projection is approximately 400 permanent positions.
Run the property on today’s rent, realistic vacancy, insurance, taxes, utilities and maintenance. Ask who the likely tenant is and whether the property works without assuming permanent appreciation or a constant stream of mine-related renters.
Five questions worth answering before this news changes your plan
- Is the employment or income supporting my decision stable today?
- Can I comfortably carry the home without depending on every dollar of overtime or bonus income?
- Does the location work for my commute, services and day-to-day life?
- What do current listings and recent comparable sales say about value?
- Would I still be comfortable with this decision if the mining or housing market softened for a period?
If those answers hold up, yesterday’s announcement can be useful supporting context. If they do not, the announcement is not a reason to force the move.
My final take
The best part of the Craig Mine news is not the size of the investment. It is the longer local horizon.
The shaft is complete. The ore has been reached. The production ramp is beginning, and Glencore is talking about Sudbury nickel beyond 2040. That supports confidence in the local economy and in the network of workers and businesses built around mining.
It still does not tell you what to pay for a house or what your home is worth. Those answers remain local, current and property-specific.
For a broader look at how employment, infrastructure and investment connect to housing, read my Greater Sudbury real estate economic outlook and why our market does not always follow the national narrative.
Good local news matters. Use it as context, check the numbers that apply to you, and make the move because it works for your life.
