Estimates for a small start in Canada, not guarantees.
What it is
A small workshop with a used manual lathe and mill, or compact benchtop machines. You make one-off and short-run parts: replacement shafts, bushings, brackets, custom fittings and prototypes.
Your first three steps
- Check your municipality's zoning and home-based business rules, and ask your insurer whether workshop activity is covered
- Find used machines and tooling through local auctions and classifieds, and get any training you need on the machines you buy
- Contact local farms, repair shops and small manufacturers with a one-page list of what you can make, and quote a first job
Who pays
Farmers, small manufacturers, hobbyists, motorcycle and classic-car owners, tradespeople and inventors who need a part that is not sold off the shelf.
How it makes money
Hourly shop rate or fixed price per job, plus material. Repeat work from a handful of local businesses is what keeps it steady.
Skills that help
- Reading engineering drawings
- Precise measuring and setting up machines
- Quoting jobs accurately
- Basic CAD or sketching a part from a sample
Watch out for
- Zoning, noise and neighbour complaints; some municipalities limit industrial activity at home
- Commercial general liability insurance, and check that your home insurance does not exclude business use
- Power supply: larger machines may need three-phase power or a phase converter
- Safe disposal of cutting oil, coolant and metal swarf; check local rules
- Machine safety: guarding, eye and hearing protection, and training before using each machine
- Winter heating of an unheated garage, which affects both comfort and machine accuracy

Questions people ask
How much does it cost to start a home machine shop in Canada?
Estimates suggest startup costs are typically around $8,000 to $35,000, depending on whether you buy used manual machines or compact benchtop ones, plus tooling, measuring gear and workshop setup.
How much can a garage machining business earn?
Monthly revenue is typically estimated at around $800 to $4,000, depending on the hours you put in, the jobs you win and your pricing. Revenue is not profit, so allow for tooling, power and insurance costs.
What rules should I check before machining from home in Canada?
Check municipal zoning and noise rules, since some limit industrial activity at home. Also check that your home insurance doesn't exclude business use, whether larger machines need three-phase power, and local rules for disposing of cutting oil, coolant and swarf.
