Setting the business up7

Start your business in OntarioThe eight setup stages in order, from incorporation through CRA, WSIB and licensing to bid ready: walk the three-step wizard to a live name check and an all-in filing price with government fees included, free and with no account, nothing filed until you authorize and pay.Sole prop or incorporateThree paths priced on one screen: $100 for an Ontario sole proprietorship, $400 for an Ontario corporation, $300 federal, with the government filing fees inside each number. Fill the whole registration in, right to the review screen, before any account is needed.We file it for youOne checkbox hands over the Articles of Incorporation and the four CRA program accounts. See the exact wording you authorize, which steps stay yours, what the all-in price covers, and the one panel every number lands in afterwards.What going out on your own costsTwo numbers decide this and only one gets discussed. The setup fees are hundreds. The gap between doing the work and being paid for it is thousands, and it is the one that closes businesses.Going independent, pricedWSIB, CPP at both halves, income tax, HST after $30,000, insurance and plates all arrive together. Add up your real monthly overhead, run it through a six-month cash forecast, and get the number that has to go on top of your rate.Bring your businessYou registered something, started charging, got work. Then a builder asked for a certificate you did not have. Drop your documents in, have the numbers read out of them, and land on a compliance checklist with what you already satisfy already ticked.IncorporationNamed vs numbered companies, Ontario vs federal incorporation, directors, share structure, and the step-by-step filing process.

Finding work5

Where work is startingA live feed of Ontario employers who just pulled a building permit or won a contract, filtered to your trade. A permit is earlier than a job ad: read the signal like an estimator, track it in one click, and get a weekly heads-up by email.Find open Ontario tendersPublic tenders are scattered across MERX, Biddingo, Bids and Tenders and dozens of buyer portals, each with its own login. Get the live Ontario ones in one list: search the thing you build, read a record in a minute, and track a bid onto your pipeline board in one click.Hear about work earlyTransmission lines, environmental filings, rezonings and agency capital plans are projects announcing themselves years ahead. Get them filtered to your trade and region, grouped by how far in front of the bid each one sits.First public bidPublic work is not harder work, it is work with a filing cabinet attached. See what is actually open with closing dates, then find you already hold a controlled document library with the company profile and prequalification package in it.Get on GC bid listsThere is no register to sign and no form to fill. Work arrives because somebody at a builder has your name in front of them. Find the person, send them something worth keeping, and be able to answer the prequalification package when it comes.

Bidding and prequalification6

The bid-ready checklistIncorporating is the starting gun, not the finish line. Ten stages generated for your trade, the next three things to do at the top, and a percentage that moves for the right reasons.First public bidPublic work is not harder work, it is work with a filing cabinet attached. See what is actually open with closing dates, then find you already hold a controlled document library with the company profile and prequalification package in it.Know if they read itAn evening on a price, then silence, and no way to tell whether it landed in spam or was read and rejected. Send the proposal as a page instead of an attachment and it reports back: what they read, for how long, and what they skipped.Respond to an RFPTurn an RFP into traceable requirements, questions, quantities and a commercial response. Keep the offer tied to the drawings, specifications and assumptions that support it.Bid ReadinessPrequalification packages, bid documents, bonding, estimating, and how construction companies actually get work.ISO ComplianceISO 9001, 14001, 45001, implementation roadmaps, and how management systems help you win larger contracts.

Project documents & delivery5

Prepare an RFPBuild an RFP from the decision, evidence, requirements and response structure that make bids comparable. Keep issued documents, clarification and changes connected to the project record.Respond to an RFPTurn an RFP into traceable requirements, questions, quantities and a commercial response. Keep the offer tied to the drawings, specifications and assumptions that support it.Review drawings and revisionsEstablish the current project set, compare drawing versions, reconcile specifications and record actionable findings with their evidence, owner and disposition.Reconcile quantities and quoteTrace quantities to evidence, map scope to commercial lines and check the resulting quote for omissions, conflicts and assumptions before it is sent.Connect RFIs and handoverUse an evidence-linked project register for RFIs and submittals, then carry the governed records into a usable handover and asset information set.

Pricing and estimating9

How much to chargePrice one real job end to end: every cost on its own line, markup you set on purpose, Ontario HST applied for you, holdback split into what you bill now and what waits, and one list of every quote out with its status and value. Demo business, no signup.What an hour costs youThe wage is roughly half what a worker costs. Add the employer side, the truck, the tools and the insurance, divide it across the hours you can actually invoice, and get a floor under your rate before the quote goes out.What going out on your own costsTwo numbers decide this and only one gets discussed. The setup fees are hundreds. The gap between doing the work and being paid for it is thousands, and it is the one that closes businesses.Assumptions you can defendEvery argument about a quote is two people remembering a conversation. Two short paragraphs on the quote itself, scope and exclusions, turn that into a comparison of documents.Charge for the estimateSomebody wants a boiler sized or a panel schedule laid out, and what they are buying is your judgement. Put the design fee on the quote as its own line, credited against the contract, and make paying it a single tap.Going independent, pricedWSIB, CPP at both halves, income tax, HST after $30,000, insurance and plates all arrive together. Add up your real monthly overhead, run it through a six-month cash forecast, and get the number that has to go on top of your rate.Win rate and your priceA win rate is a score, not a diagnosis. Put the size of what you lose next to the size of what you win, read the reasons you lost, and check what the wins actually made before you come down on price.Send your own quoteMost contractors who price well already have a spreadsheet that took years to get right. Software arrives and asks them to abandon it. Upload the file instead, have the lines read out of it, and choose whether the client opens your document or the platform version.Reconcile quantities and quoteTrace quantities to evidence, map scope to commercial lines and check the resulting quote for omissions, conflicts and assumptions before it is sent.

Change orders and extras2

Change orders that get paid When they say no to an extra

Getting paid6

Invoice and get paid on timeBuild the invoice straight from an accepted quote, with HST at 13 percent and the 10 percent Construction Act holdback computed for you. Send it with a timestamped record, log partial cheques, and put every held-back dollar on a countdown.Surviving net 60Materials and payroll go out weeks before the money comes in. Bill against a schedule of values as the work happens, see what is outstanding against what is genuinely late, and keep the holdback out of the number you think you have.When a client will not payFive steps in the order that costs least: check whether they ever opened it, send the reminder from your business, read the statutory dates, put it in writing, then pick the remedy that matches the amount.Prompt payment clocksOntario gives the payer 28 days to pay a proper invoice and 14 to dispute it, and gives you 7 to pay your own subs once you are paid. Put in one date and every deadline it sets is counted, with the section it comes from.Charge for the estimateSomebody wants a boiler sized or a panel schedule laid out, and what they are buying is your judgement. Put the design fee on the quote as its own line, credited against the contract, and make paying it a single tap.Paying subsPaying a sub is three jobs: pay them, prove everyone under you is paid, and report it to CRA. The statutory declaration that releases holdback is already generated, the subcontractor agreement starts the paper trail on day one, and the T5018 totals itself from your books.

C of Q and apprenticeship5

Dealing with Skilled Trades OntarioNothing gets Skilled Trades Ontario to answer the phone faster. What you control is knowing your own expiry dates early enough to act, and building a dated paper trail while you wait rather than after you have lost.Finding a sponsorYour hours only count if an employer signs you up, and almost nobody advertises the position. Work from the public record of who just pulled a permit in your trade and your city instead of a queue with no front.Challenging the C of QThe assessment is a documentation exercise, and what stops people is a work history written in the wrong language. Get the hours, the scope and the people who will confirm them down while you still can.Provisional C of Q expiringIf you have just opened the notice and your stomach dropped, start here. Book the seat before you study, count backwards from the seat rather than forwards from today, and get your options from STO in writing.C of Q, then whatYour ticket lets you do the work. Something else entirely lets you sell it. Read the Last Mile guide for your code to the end, find out whether your trade needs a contractor licence, and look around a working business before you file anything.

Books that stand up4

Receipts out of the shoeboxFiling a $47 receipt costs more attention than the $47 is worth on the day, so it waits until January. Photograph it in the parking lot, check what was read off it, and claim the HST you paid instead of losing it.Did I make money this monthThe bank balance is a mix of last month's invoices, next month's HST and a deposit on a job that has not started. Read the month, split it by job, and learn the difference between a job losing money and a job you have not invoiced yet.HST without the surpriseNobody writes to tell you that you crossed the threshold. Register on time, charge it on the whole invoice, keep the collected money separate, and read your return on the CRA's own line numbers before you sit down with your accountant.Books that stand upThe fear is being asked a question about your own business and not being able to answer it. The way out is records made as the work happens, by the system that raised the invoice, so there is nothing to reconstruct in March.

Running the day11

Admin by emailLogging in to answer a one line question costs more than the question is worth, so it waits until night. Your business has an email address: ask it what is outstanding and the answer comes back with your own invoices, jobs and calls in it.Every job on one boardAsk a contractor what they are chasing and you get three jobs and a pause. The pause is where a quote sits for five weeks. One board with the money on each column, and a fifteen minute weekly habit.Run your back officeKeep recurring construction office work connected to the records that matter: pipeline, quotes, invoices, documents and Books, with role-based team access.Pushed to incorporateOpen a company, keep the same hourly rate, add HST. It sounds like a favour and it is a transfer: everything your boss pays on top of your wage becomes yours. Run the arithmetic on what moves, see the tests CRA and WSIB actually rule on, and price the real version if you go anyway.First employeeThe first hire is three jobs: registrations that make it legal, paper that makes the deal clear, and a price you should know before the ad goes up. The payroll deductions account is a checklist item, the employment agreement is generated, and the WSIB card prices the hire with your own rate.One place, not five toolsContractors build their own spreadsheets because every app was missing the thing that makes construction different, and because a monthly bill for something that still needs a workaround is infuriating. Holdback, per-job profit and the T5018, in one place, with no monthly bill.Paying subsPaying a sub is three jobs: pay them, prove everyone under you is paid, and report it to CRA. The statutory declaration that releases holdback is already generated, the subcontractor agreement starts the paper trail on day one, and the T5018 totals itself from your books.Team accessWhat would fix a contractor’s admin is almost never a feature. It is a person: a bookkeeper, an office manager, a partner who already does the invoicing. Three roles, an email address, and an accountant export that means they never need a login at all.One screen every morningThe worst part of running a contracting business is the twenty minutes before the work, spent reconstructing what happened yesterday. A briefing written each morning from your own invoices, deals and books, ranked so the top card is the one that matters.Try it as a working businessAn empty trial account tells you nothing. Pick your trade and land in a business partway through its year: money in play, an invoice fourteen days overdue, change orders on a live job, books that balance.Operational SetupBusiness banking, construction-specific accounting, payroll setup, trust obligations under the Construction Act, and day-to-day operations.

Being findable6

Marketing on scheduleMarketing slides at exactly the wrong moment: you are busiest when the pipeline is full, then it empties and you start from a cold account. A ready-to-post pack every morning, written from your own city, pipeline and won jobs.Brand, website, documentsThe decision takes a sentence. The admin that follows takes a fortnight: a logo, a colour picked in a hurry, a website that never gets finished, and documents written the night before a builder asks for them. One press produces all three, in one brand.Know if they read itAn evening on a price, then silence, and no way to tell whether it landed in spam or was read and rejected. Send the proposal as a page instead of an attachment and it reports back: what they read, for how long, and what they skipped.Get on GC bid listsThere is no register to sign and no form to fill. Work arrives because somebody at a builder has your name in front of them. Find the person, send them something worth keeping, and be able to answer the prequalification package when it comes.Business EmailGoogle Workspace, Microsoft 365, Zoho Mail, email forwarding — every option compared with step-by-step DNS setup instructions.Custom DomainRegister your own domain, point DNS to your AEC Stack website, and go from yourcompany.aecstack.com to yourcompany.ca.

You charge HST on the full value of the work, including the tenth being held. You do not remit all of it yet. Enter the job and get both numbers, and the date the rest falls due.
Do you have to charge HST yet?
The small supplier threshold has two tests. The one that catches a contractor is the single quarter test, and it has no grace month. Enter your quarters and see which one bites first.
Markup and margin calculator
Add twenty percent to your costs and you keep sixteen point seven. Enter one job and see the price, the profit, both percentages, and what the mix-up is worth in dollars.
Ontario filing deadline calendar
Every date a contractor owes the CRA and WSIB, counted from your own year end. Including the T5018, which is the one that surprises people.
Ontario lien deadline calculator
Last day on site and contract date in. Preservation, perfection and the annual holdback dates out, counted with the periods in the Construction Act.
Ontario prompt payment calculator
One date in: the day you gave them a proper invoice. Out comes the day they have to pay, the day they had to dispute it, and the day you owe your own subs whether or not you were paid.
WSIB premium calculator
What WSIB costs you this year on your own crew, and what it can cost you a second time on the subcontractors you never collected a clearance certificate from.

The dates that cost Ontario contractors money

One email a month. What is due at CRA and WSIB, the Construction Act clocks that started running on your last invoice, and every new guide the day it goes up.

Your lien clocks, counted for you. Preserve is 60 days under section 31 and perfect is a further 90 under section 36, and neither one can be extended once it has gone.
The remittance and filing dates for the month ahead, so HST and WSIB stop arriving as a surprise and the T5018 stops being a January problem.
Every new guide the day it goes up. 109 are live for Ontario right now, the most recent being "Prepare an RFP" on 19 September 2026.
