What Mississauga Businesses Need from a Business Lawyer
According to the City of Mississauga's 2024 Employment Survey, 84% of businesses in the city employ fewer than 20 people. That means the vast majority of Mississauga business owners are navigating complex legal requirements without a dedicated in-house legal team, which is exactly where we come in.
A Mississauga business lawyer advises on the legal structure and relationships that define how your company operates. That covers two interconnected areas: corporate law, which governs the internal structure of your business (incorporation, governance, shareholder rights, reorganizations), and commercial law, which governs the external relationships your business relies on (contracts, leases, supplier agreements, employment terms). As your company grows, you also need guidance on transactional work: buying or selling a business, structuring acquisitions, or navigating financing arrangements.
The distinction matters because the legal risk profile changes at every stage of a business. At incorporation, the priority is getting your structure right and protecting founders from personal liability. Mid-growth, it is about enforceable contracts and governance that scales. At exit, it is maximising value and managing representations and warranties. Our lawyers advise at each stage, not just at the moments of crisis.
Incorporating a Business in Mississauga
The most common starting point for Mississauga business owners is incorporation. Incorporating separates your personal assets from your company's liabilities, can reduce your personal tax burden through income splitting and the small business deduction, and lends credibility to your business in the eyes of clients, lenders, and partners.
Ontario or Federal: Which Incorporation Is Right for You?
If your business operates primarily in Ontario, incorporating under the Ontario Business Corporations Act (OBCA, R.S.O. 1990, c. B.16) is typically the right choice. The process involves preparing Articles of Incorporation, conducting an NUANS name search, and filing through the Ontario Business Registry. A government fee of $300 applies. If your business operates across multiple provinces or benefits from a nationally recognised corporate name, federal incorporation under the Canada Business Corporations Act (CBCA, R.S.C. 1985, c. C-44) may be more appropriate.
For licensed professionals (lawyers, accountants, physicians, dentists), professional corporations offer distinct advantages: liability protection and tax deferral through a regulated structure unique to each profession.
Our lawyers guide you through the choice and handle the full incorporation process: Articles of Incorporation, initial resolutions, share issuance, bylaws, and your corporate minute book. Getting this foundation right avoids costly restructuring later.
Beyond Incorporation: Corporate Maintenance
Incorporation is the beginning, not the end. Ontario law requires corporations to maintain accurate minute books, pass annual resolutions, and file annual returns with the Ontario Business Registry. Directors of Ontario corporations owe fiduciary duties under the OBCA (s. 134), including a duty of care and a duty to act in the corporation's best interests. When these obligations are not met, directors can face personal liability.
We handle ongoing corporate maintenance so your company remains in good standing and your minute book accurately reflects ownership, share structure, and governance decisions.
Shareholders' Agreements: Protecting Business Partnerships
Most businesses start with good intentions between partners. But without a written shareholders' agreement, a dispute over management decisions, a founder's departure, or a disagreement over profit distribution can paralyse or destroy a company that took years to build.
A shareholders' agreement is a private contract between the shareholders of a corporation that governs their rights and obligations beyond what is set out in corporate statutes. It addresses the critical questions that the OBCA does not: who controls day-to-day decisions, what happens when a shareholder wants to sell their shares, how are disputes resolved, and what triggers a buyout.
Unanimous Shareholder Agreements
A unanimous shareholder agreement (USA) is a specific form of agreement recognised under both the OBCA (s. 108) and the CBCA (s. 146) that can restrict or transfer the powers of the board of directors to shareholders. A USA requires the signatures of all shareholders and is binding on any future shareholder who acquires shares, meaning share certificates must note its existence. The power shift carries corresponding responsibility: under both statutes, shareholders who assume director powers through a USA also assume the directors' legal obligations.
We draft shareholders' agreements for businesses at every stage, from two-person startups to multi-stakeholder Mississauga enterprises. If you are bringing on investors, promoting an employee to equity, or formalising a long-standing partnership, this is the right moment.
Commercial Contracts for Mississauga Businesses
Mississauga's economy runs on contracts. Whether you are a manufacturer with dozens of supplier relationships, a logistics operator negotiating with carriers, a franchise owner reviewing your franchise agreement, or a service business with recurring client contracts, the agreements you sign define your risk exposure and your revenue protection.
Commercial contracts that our lawyers draft and review include:
- Service agreements and master service agreements (MSAs)
- Supply and distribution agreements
- Franchise agreements (for both franchisors and franchisees)
- Independent contractor agreements
- Non-disclosure and confidentiality agreements (NDAs)
- Letters of intent and term sheets
- Loan agreements and commercial financing documentation
A poorly drafted contract can leave critical obligations ambiguous, fail to cap your liability in a dispute, or create unintended exclusivity arrangements. Our lawyers ensure the agreements you sign reflect the deal you actually negotiated, and protect you if the relationship sours.
Commercial Leases for Mississauga Businesses
Commercial leases are among the most significant legal commitments a Mississauga business will make. Unlike residential tenancies, Ontario's commercial tenants have no statutory protection under the Residential Tenancies Act. The terms you negotiate at the outset (rent escalation, permitted use, assignment rights, personal guarantees, renewal options, and restoration obligations) are the terms you live with for the duration of the lease.
Mississauga's commercial real estate market has shifted meaningfully in recent years. Large industrial spaces previously occupied by logistics operators have been vacating, and mid-sized businesses are stepping in with more negotiating power than existed five years ago. Our lawyers help you understand your position in the current market and negotiate lease terms that reflect it.
What We Review in a Commercial Lease
Before you sign, we examine:
- The rent structure: base rent, additional rent (TMI/NNN), and escalation mechanisms
- Permitted use clause: whether it is broad enough to cover your current and future operations
- Assignment and subletting provisions: your flexibility if the business changes
- Personal guarantee obligations: scope and whether guarantees can be limited or released
- Renewal and expansion options: rights that must be negotiated before signing, not after
- Restoration clauses: whether you will be required to return the space to its original condition at the end of the term
A commercial lease review is one of the highest-return legal investments a Mississauga business can make.
Buying or Selling a Mississauga Business
Mississauga's business community includes thousands of companies built over the past two decades by entrepreneurs now approaching natural exit points. Whether you are selling the business you have spent years building or acquiring an established company to accelerate your growth, the transaction structure you choose has significant legal and tax consequences.
Asset Sale vs. Share Sale
In an asset sale, the buyer purchases specific assets of the business (inventory, equipment, customer contracts, goodwill) leaving most liabilities with the seller. In a share sale, the buyer acquires the company itself, including all of its assets, contracts, employees, and liabilities. Buyers generally prefer asset purchases because they avoid inheriting undisclosed liabilities; sellers often prefer share sales because of the capital gains exemption available on qualifying small business corporation shares.
Nicholas Dempsey, our corporate lawyer, has worked on more than 90 asset and share sale transactions. He advises both buyers and sellers on deal structure, due diligence, purchase agreements, and closing mechanics. Nassira El Hadri, our founder and principal lawyer, brings additional depth from her prior experience advising banks and credit unions on corporate acquisitions and financing transactions.
What Due Diligence Covers
Before a deal closes, a buyer needs to review the seller's contracts (including assignment restrictions), lease obligations, employment agreements, corporate records, outstanding liabilities, and regulatory compliance history. Our lawyers manage the due diligence process to surface risks before they become post-closing disputes.

Frequently Asked Questions
What does a business lawyer do in Ontario?
A business lawyer advises companies on the legal structure and relationships that govern how they operate. This includes incorporating the business, drafting and reviewing contracts, advising on shareholder agreements, handling commercial lease negotiations, and structuring the purchase or sale of a business. The goal is to prevent legal problems before they arise.
Do I need a lawyer to incorporate in Ontario?
Ontario does not legally require a lawyer to incorporate, but professional guidance is strongly advisable. A lawyer ensures you choose the right structure (OBCA vs. CBCA), draft proper Articles of Incorporation and bylaws, issue shares correctly, and set up your minute book. Foundations built incorrectly are expensive to correct after the fact.
What is the difference between corporate law and commercial law?
Corporate law governs the internal legal structure of a business: incorporation, governance, shareholder rights, director duties, and reorganisations. Commercial law governs the external relationships: contracts with clients and suppliers, commercial leases, franchise agreements, and financing arrangements. Most business lawyers advise on both, as the two areas overlap in most business transactions.
What should I look for in a commercial lease agreement?
Before signing a commercial lease, review the rent escalation provisions, permitted use clause, assignment and subletting rights, personal guarantee requirements, renewal options, and restoration obligations at the end of the lease. Commercial tenants in Ontario have no statutory protection, so the negotiated terms are the only terms that apply.
What is the difference between an asset sale and a share sale?
In an asset sale, the buyer acquires specific business assets and leaves most liabilities with the seller. In a share sale, the buyer acquires the company itself, assets and liabilities together. Sellers often prefer share sales for potential access to the lifetime capital gains exemption on qualifying small business corporation shares. Buyers often prefer asset purchases to avoid inheriting undisclosed obligations.
