# Lawyer for Buying a Business in Ontario Canonical: https://www.pcbodirectory.ca/education/lawyer-buying-business-ontario By PCBO Directory | Published: 2026-10-19 | Updated: 2026-10-19 For buying an existing business in Ontario, look for a corporate and commercial lawyer who handles business acquisitions. Ask about experience with asset purchases, share purchases, due diligence and closing. Lamba Law is a Mississauga firm whose published services include business purchases and sales. This guide helps buyers prepare for a first legal meeting and compare the scope of an engagement. ## Your first legal meeting Bring the draft offer or letter of intent, the target business name, your financing plan and key dates. Have counsel explain what you would commit to before you sign or pay a deposit. ## What does a business purchase lawyer do? A business purchase lawyer helps turn the proposed deal into documents and conditions that address the buyer’s risks. Ask which parts of the transaction the engagement covers: early negotiations, legal investigation, purchase agreement, required consents, financing documents and closing. Your accountant examines the financial and tax position; the lawyer addresses the legal terms and coordinates issues that overlap. A lender makes its own funding decision. Ask how these advisers will share information and who will track unresolved items. [BDC’s guide to acquisition advisers](https://www.bdc.ca/en/articles-tools/start-buy-business/buy-business/whose-advice-seek-when-buying-business) explains the different roles on a buyer’s team. ## Should you buy assets or shares? In an **asset purchase**, the agreement identifies what is transferred and which obligations are assumed. In a **share purchase**, the corporation remains in place while its ownership changes. The corporation’s existing obligations make investigation important. Neither structure removes every risk. Give counsel the proposed structure and ask what it means for contracts, licences, debts and employee matters. Ask your accountant about purchase-price allocation and tax treatment before agreeing to the structure.

For a broader introduction, read PCBO’s [buying and selling a business guide](/education/buying-selling-business-ontario). ## When should you contact a lawyer? Arrange legal review when you have a serious target and proposed terms, before signing an offer, exclusivity promise or letter of intent. Ask counsel to identify any binding provisions, deposit terms and deadlines in the actual document. A label such as “LOI” does not tell you the effect of every clause. If you have already signed, send the complete document and all amendments promptly. Tell the lawyer about deposits paid, conditions still outstanding and approaching dates. [BDC describes how an LOI and investigation fit into the acquisition process](https://www.bdc.ca/en/articles-tools/start-buy-business/buy-business/what-are-steps-buying-business). ## What should you ask before hiring a business purchase lawyer? Use the same questions when discussing a quote with each firm: - Does your proposed scope include the LOI, legal due diligence, negotiations and closing? - Who will work on the file and coordinate with my accountant and lender? - Which searches, third-party costs and government charges are additional? - What information do you need to assess timing and conflicts? - How will you explain unresolved risks before I decide whether to proceed? - What work would require a revised quote? Describe the business, location, asset or share structure, lease and financing. These details help the firm assess the work. Request written scope and fee terms, including the assumptions behind the quote and proposed timeline. ## What should a buyer bring to the first meeting? Start with the target’s legal name, seller and buyer names, the proposed price and the latest draft documents. Include any confidentiality agreement, lease summary and financing conditions already discussed. Give the firm party names for its conflict check before sharing sensitive business records. List what you have verified, what you have only been told and what remains unavailable. For example, “the seller says the lease can transfer” should remain an open question until the lease and required consent are reviewed. PCBO’s [business purchase due diligence guide](/education/business-purchase-due-diligence-ontario) helps organize that list. ## Lamba Law: business purchase legal services in Mississauga Lamba Law lists asset and share purchase agreements, due diligence coordination, vendor financing, transition arrangements and closing work among its [business transaction services](https://www.lambalaw.ca/services/buying-selling-business).
