Non-metallic mineral mining and quarrying

This industry group comprises establishments primarily engaged in mining or quarrying non-metallic minerals, except coal. Primary preparation plants, such as those engaged in crushing, grinding and washing, are included. — Statistics Canada, NAICS 2022A

Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Largest four provinces by establishment count. Establishments with employees only — sole operators with no payroll are not in this table, so in trades and personal services the true number of businesses is higher.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

How businesses here compete

The structural profile of subsector 212, which every industry beneath it inherits. This is analyst judgment from how the subsector is organised — not research into this industry, and not a measurement.

international competitionhigh capitalUNVERIFIEDinherited from 212 Mining and quarrying (except oil and gas)

Decade-long permitting and nine-figure capital. Aggregates and quarrying are the exception: local, haul-distance-bound and occasionally reachable.

Who sets the price: Global metal and mineral markets.
The software it runs on: Mine planning, geology modelling, fleet dispatch and safety systems.

binding constraint: entry cost + regulatory drag

Most of this group by count is sand, gravel and crushed stone; the rest — potash, salt, diamonds, gypsum — is nine-figure mining that was not examined. The record at Ready-Mix Concrete & Aggregates argued from structure that the permit is the business. This one tests that with a price series, and the test holds. Vulcan Materials shipped 226.8 million tons in 2025 at a freight-adjusted US$21.98 a ton, up 4%, and kept US$11.33 of that as cash gross profit, up 7% [A]. A commodity that holds a better-than-50% cash margin and raises price through a soft construction year is not behaving like a commodity; it is behaving like a local franchise rationed by licence. Ontario shows the rationing: 3,565 licences on private land produced 167.9 million tonnes in 2023, down 3.2% [A] — yet only 348 Ontario establishments are classified to this code, so a large share of those licences evidently sit inside road builders and concrete producers who mine for their own jobs. That is the entrant's problem from both ends. A new licence means years of rezoning, hearings and appeals with no revenue; an existing one is bid for by Vulcan-type consolidators and by the local paving contractor who needs the stone more than any financial buyer does. 53% of the 1,028 establishments have fewer than ten employees, and they are mostly families who got their licence decades ago.

Software serving this industry

The vertical software markets filed along the same branch — who sells to these businesses and who they would have to displace — and then the generic categories every business buys whatever it does.

No vertical software market has been recorded along this branch. What the subsector typically runs on: Mine planning, geology modelling, fleet dispatch and safety systems.

And what every business buys · 25 generic categories

Sold to every industry rather than this one, so they are filed against the software industry's own code. The same few vendors recur across most of them.

Every company this research names that is filed here or beneath — the operators, and the vendors that sell to them — largest disclosed revenue first. The rank is within the company’s own six-digit industry.
