To sue a business in Mississauga, first identify its legal form through an Ontario corporate profile or business names search: corporations are sued in their exact registered name (often a numbered company behind the storefront brand), sole proprietorships are sued as the owner personally carrying on business under the name, and partnerships can be sued in the firm name. Serve corporations at their registered office or on a director, officer, or person apparently in control at a place of business. Claims up to $50,000 file online, with Mississauga cases administered at the Davis Courthouse serving Peel — and businesses that ignore claims can be noted in default.
- The name on the sign is marketing, not a defendant — the registry search reveals who you sue.
- Corporations: exact legal name. Sole proprietors: the owner personally, c.o.b. the trade name.
- When in doubt, name the candidates in the alternative — extra defendants beat wrong ones.
- Owners are personally liable on real grounds: guarantees, pre-incorporation deals, their own misrepresentations.
- Serve at the registered office or on someone apparently in control — and document it.
- Business judgments collect well: accounts, receivables, equipment — while the business operates.
Why Business Cases Fail on Names
Small claims judgments bind the person named in the claim — nothing else. Sue “Platinum Home Improvements” when the entity that took your money was 2891447 Ontario Inc., and your judgment may bind a trade name with no bank account, no assets, and no legal existence: unenforceable paper. This is the single most common way Mississauga consumers and small businesses lose winnable cases — against contractors, gyms, dealerships, movers, and online sellers — and it is entirely preventable with an hour of searching before the claim is drafted. The discipline pays twice, because the same search that names the defendant correctly also tells you where to serve them and whether they're worth suing at all (an active corporation with a Dundas Street storefront collects very differently from a dissolved shell). Everything in the wider Mississauga filing process works better when this step comes first — and everything after this paragraph is that step, done properly.
The Four Business Forms
Every business you might sue in Peel takes one of four legal forms, each sued differently. A corporation (“Inc.”, “Ltd.”, or a numbered company) is a separate legal person: you sue the corporation in its exact registered name, and ordinarily the owner's personal assets sit beyond reach. A sole proprietorship is not separate at all — the “business” is a person with a registered trade name, so you sue the owner personally, styled “[Owner], carrying on business as [Name]” — and the owner's personal assets stand behind the judgment. A partnership can be sued in the firm name, reaching partnership assets, with partners exposed individually. And the unregistered operator — the cash-economy crew with no registration anywhere — is simply sued personally by name. The form dictates the defendant, the service address, and the collection strategy, which is why identifying it is step one of the case rather than a clerical detail at the end.
The Corporate Search
Ontario's registry answers the identity question for a modest fee. A corporate profile report on a suspected corporation returns its exact legal name, corporation number, status (active or dissolved), registered office address, and directors and officers with addresses — the complete targeting package. A business names search runs the other direction: feed it the trade name from the sign or invoice and it returns the registrant — a corporation (now pull its profile) or an individual (your sole proprietor). Gather search inputs from your own paper first, because Mississauga businesses are gloriously inconsistent: the name on the contract, the payee on your e-transfers, the entity on the receipt, the footer of their emails — each variant is a lead, and mismatches between them are themselves useful (they often reveal the numbered company behind the brand). Twenty minutes of searching resolves even a deliberately murky operation into a nameable defendant — and flags the dissolved ones before you spend a filing fee on a ghost.
Drafting the Style of Cause
Draft from the search, not the signage: the corporation's exact registered name, letter for letter and suffix included; the sole proprietor as “[Owner], c.o.b. as [Trade Name].” Where the searches leave genuine ambiguity — the contract names the brand, the deposit went to a numbered company, the owner signed without indicating capacity — the robust move is to name the reasonable candidates as co-defendants: the corporation, the individual, and the trade name. The court is forgiving of suing an extra party and unforgiving of suing the wrong one; a defendant who doesn't belong can say so in a Defence and misnomers can be amended, but a judgment against the wrong entity discovered after trial is a disaster no amendment cures. The usual drafting rules still govern: the $50,000 ceiling, the two-year limitation (check yours with the limitation period calculator), interest pleaded via the interest calculator, and a chronological story with the documents attached — the craft our filing guide drills.
When Owners Are Personally Liable
The corporate shield is real but not absolute, and Mississauga claims against small corporations should always ask whether an individual belongs in the claim too. The recognized routes: the owner personally guaranteed the obligation; they contracted before incorporation or without disclosing the corporation (you reasonably thought you were dealing with the person); they committed a tort themselves — the misrepresentation they personally made to get your deposit is their tort even if the contract was corporate; or deposits were taken with no apparent intention or capacity to perform, which shades toward fraud no incorporation launders. Pleading a supportable personal claim alongside the corporate one transforms settlement dynamics — an owner defending their own Lorne Park house negotiates differently than one defending an empty Inc. — but plead only what the facts support: deputy judges have seen reflexive owner-naming and discount it. The genre where personal liability matters most is the one Peel produces in volume — contractor files — covered wall to wall in our Mississauga contractor guide.
Serving a Peel Business
Service rules for businesses are friendlier than defendants expect. A corporation is served by leaving the claim with a director, officer, or person apparently in control at any place of business, or at the registered office from the profile report — and where the registered office is stale, documented attempts build the record for substituted service. A sole proprietor is served like any individual, at home or at the shop. The practical Peel pattern: serve the storefront or unit during business hours and ask for the manager — the “apparently in control” standard is generous, and a process server's affidavit describing the counter handoff holds up. Document everything: business defendants who default later surface claiming they were never served, and the affidavit of service is what defeats the set-aside motion. Industrial-unit defendants — Peel's specialty, from Dixie to Meadowvale Business Park — reward serving early in the day, before crews scatter to job sites and the unit locks up behind a camera doorbell.
Filing & How Business Defendants Behave
Filing runs the standard Mississauga route — online portal, $108, the file administered at the Davis Courthouse serving Peel, service within six months, the defendant's 20-day clock (the whole sequence in our complete guide). Business defendants then split into predictable camps. A meaningful share default — small operations ignore mail and assume you'll go away — and your properly served claim converts into a judgment on paper. Defended files head to the settlement conference, where businesses are frequently commercial about outcomes: they weigh legal spend, the owner's time, and reputational exposure against your number, and organized plaintiffs settle a high percentage there. One asymmetry worth using: corporations appear through a lawyer, paralegal, or (with permission) an officer — meaning a corporate defendant often must pay professionals to fight a $12,000 claim, pressure you should price into every offer. Before filing at all, pressure-test the dispute with the should-I-sue wizard and send the demand letter — licensed, reputation-conscious businesses respond to credible pre-suit demands at rates individuals never match.
Dissolved & Disappeared Businesses
Sometimes the search returns bad news: the corporation is dissolved, the unit is dark, the phone disconnected. Options narrow but remain. Dissolved Ontario corporations can still be sued within statutory windows; personal claims survive dissolution — the guarantee, the personal misrepresentation, the pre-incorporation deal — against owners who remain findable; and successor operations matter: the same owner reopening the same business under a fresh numbered company is a familiar Peel pattern, and claims against the individual plus scrutiny of where the old company's assets went can follow the value. But be honest about economics before spending fees on a shell: collectability is the gate, and a judgment against an empty entity is the most expensive paper in litigation. This is where a half-hour of professional triage earns its keep — we tell Mississauga clients plainly which chases are worth funding, and which amounts are better converted into a hard lesson and a better contract next time.
Collecting From a Business
The good news that balances the naming perils: business judgments are frequently easier to enforce than personal ones, because businesses have visible money. An operating Mississauga defendant has a bank account (garnishable — the payee on your own e-transfers names the institution), receivables (its customers can be garnished for what they owe it), equipment and vehicles (writ targets), and often a commercial landlord and licensing relationships that make sustained non-payment expensive. A sole-proprietor judgment reaches the owner's personal wages, accounts, and property. The full campaign — examinations, garnishment targeting, writs, sequencing — is our Mississauga enforcement guide; the business-specific headline is that a company which wants to keep operating in Peel generally pays once enforcement makes non-payment the costlier option.

Frequently Asked Questions
Run an Ontario business names search on the trade name from the sign or invoice — it returns the registrant, either a corporation or an individual. If it's a corporation, pull the corporate profile report for the exact legal name, status, registered office, and directors. Cross-check against the payee on your e-transfers and the name on your contract.
The corporation, in its exact registered legal name — a trade name alone is not a legal person, and judgments against marketing names can be unenforceable. If the business is a sole proprietorship, sue the owner personally, carrying on business under the name. When genuinely uncertain, name the reasonable candidates as co-defendants.
Only on real grounds: a personal guarantee, contracting before incorporation or without disclosing the corporation, a tort they personally committed (like the misrepresentation that got your deposit), or money taken with no apparent intention to perform. Where the facts support it, adding the owner transforms settlement and collection; where they don't, judges discount it.
Leave the claim with a director, officer, or person apparently in control at any place of business, or serve the registered office from the corporate profile. The storefront or industrial-unit manager during business hours typically qualifies. Keep a detailed affidavit of service — it defeats the later "never served" set-aside motion.
Sue the number: numbered companies are ordinary corporations with no marketing name, and your search connects the number to the brand, registered office, and directors. Consider whether the operating individual belongs in the claim on personal-liability grounds — with numbered-company operations, the answer is often worth examining.
After the 20-day window you can note them in default; fixed-sum claims proceed to clerk's judgment on paper, other damages via a brief assessment. Business defendants default at surprisingly high rates, which is why exact naming and provable service matter — the resulting judgment gets scrutinized only if they surface to challenge it.
A corporation appears through a lawyer or licensed paralegal, or an officer where the court permits — it cannot simply show up like an individual. The cost of professional representation against a mid-sized claim is real settlement pressure on corporate defendants, and plaintiffs should factor it into every negotiation.
Not necessarily: dissolved corporations can still be sued within statutory windows, personal claims (guarantees, misrepresentation, pre-incorporation dealings) survive dissolution, and same-owner successor companies invite scrutiny of where the assets went. But weigh collectability honestly before funding a chase — sometimes the shell is genuinely empty.
More often than suing individuals: businesses respond to credible demand letters, default or settle at high rates, and are comparatively easy to collect from (accounts, receivables, equipment). Run the numbers through the should-I-sue wizard and start with a proper demand letter — many Peel business disputes end there for the cost of a stamp.
Garnish its bank account (your payment records name the bank), garnish receivables in its customers' hands, file a writ against equipment and property, and examine an officer under oath about assets. An operating business generally pays once enforcement makes non-payment the more expensive option; the campaign mechanics are in our Mississauga enforcement guide.
