Why this exists
Nobody built the toolkit for the Ontario contractor. So one of us did.
The big software companies build for accountants in the US, or for generic "field service" everywhere. None of them know what O. Reg. 213/91 says, what the OBC 2024 span tables require, or how a WSIB premium is actually classified. This toolkit does — because it was built by a working Ontario carpenter who needed all three and was tired of keeping them in three different browser tabs.
The toolkit
Three jobs, one place
The free tools answer the code and safety questions. The app runs the money. Start anywhere.
1Build to code
Ontario Building Code calculators
Spans, headers, stairs, guards, egress, deck footings, permit triggers — every value cited to the OBC 2024 clause it comes from, in imperial tape-measure fractions and metric.
2Stay compliant
WSIB & OHSA safety tools
Estimate your WSIB premium, check fall-protection and confined-space rules, size your JHSC, look up PPE requirements — referenced to current Ontario OHSA regulations and WSIB classifications.
3Run the business
The crew app — clock-in to invoice
Your crew clocks in on their phones (free seats), hours feed job costing and Canadian payroll, and billable time and materials flow straight onto a GST/HST-correct invoice. One flat price, no per-user fees.
A day on the job
From "is this to code?" to "customer got the invoice"
The free tools and the paid app aren't separate products — they're the same workday.
1
Morning — quoting
Check the span before you promise the beam.
Customer wants a bigger opening. Pull up the free Beam Span Calculator, confirm what the OBC allows, and build the estimate in the app off real numbers — not a guess you'll eat later.
2
Onboarding a hire
Know your WSIB exposure before you add the seat.
Bringing on a second framer? The free WSIB Premium Calculator estimates the premium, and the app adds their free Work Suite seat so they clock in on their phone from day one.
3
On site
Crew logs the hours, you approve in two taps.
Hours land against the job automatically. Materials get photographed and marked billable. Nothing to reconstruct at the end of the week.
4
Friday
Payroll and the invoice, off the same hours.
The approved hours run payroll (CPP, EI, current CRA rates) and the invoice pulls the unbilled hours and billable materials off the job with the right tax. Both come from the work your crew already logged.
FAQ
Common questions
Are the Ontario contractor tools really free?
Yes. Every OBC building-code calculator and every WSIB/OHSA safety tool is free forever — no sign-up, no paywall inside the tools. The only paid part is the optional business app for invoicing, payroll, and running your crew, and even that has a free trial with no credit card to start.
Who built and verified these?
A Red Seal carpenter holding an Ontario Certificate of Qualification, who runs a small contracting business in Ontario and uses these tools on his own jobs. The OBC tools reference the Ontario Building Code 2024 Compendium; the WSIB and OHSA tools reference current Ontario regulations. Each tool cites the clause or table it draws from.
Do these replace an engineer, inspector, or WSIB?
No. The OBC tools reproduce prescriptive Part 9 values for common residential conditions and flag when you leave the prescriptive path — anything engineered needs a professional. The WSIB calculator is a strong planning estimate, but your official premium comes from WSIB based on your classification and claims history. Always confirm with the authority before you rely on a number.
What does the crew app cost?
Business Pro — the plan that runs a crew — is $32/mo (or $26/mo billed annually), flat, with unlimited free seats for everyone who works for you. There are no per-user fees. If you only need invoicing and expenses without payroll, Business is $16/mo. See the full breakdown →
I work outside Ontario — is any of this useful?
The business app works Canada-wide — every province's GST/HST/PST and CRA payroll rates are built in, with QPP/QPIP for Quebec. The OBC and WSIB tools are Ontario-specific (they reference Ontario code and regulations), so contractors in other provinces should confirm their own provincial building code and workers' compensation board.
