Our professionals are members in good standing of various regulatory bodies, including the following:


Commercial companies
Your organization's financial statements are a necessary decision-making tool for your management and financial partners. So it is important that they contain accurate financial information that presents a clear picture of your company's situation according to the proper basis of accounting.

Our role as auditors is to ensure that your financial statements reflect, in all essential respects, your company's financial situation, operating results, and cash flow according to the proper basis of accounting. We have developed an auditing approach that we tailor to all types of clients in every sector. In short, auditing involves formulating an opinion on the accuracy of your financial statements. It provides the highest level of assurance.

Trusts, non-profit and charitable organizations

We act as external auditors for over 175 non-profit and charitable organizations in Ontario and Quebec. Our non-profit and institutional clients include hospitals, school boards, universities, unions, foundations, and international, national, provincial, and regional organizations working in various fields (including healthcare, education, and community, social, and cultural activities). We also act as auditors for a number of daycare centres.

We use an auditing approach adapted to the specific needs of our clients. Thanks to the expertise we have gained over the years with these organizations, we have developed effective, appropriate tools and work methods.


The review process essentially involves gathering data, and analyzing and discussing information provided by the client's management team.

Our role as chartered accountants is to make sure that everything in your financial statements complies with generally accepted accounting principles using review processes approved by the Canadian Institute of Chartered Accountants.

In summary, the review process provides a lower level of assurance than the auditing process.

Compilation (Notice To The Reader)

Notices to the reader (compilation) provide the lowest level of assurance as to the accuracy of compiled data.

Our role is to draw up financial statements based on the information provided by your company's management team. This type of mandate may be appropriate when financial statements are prepared for the exclusive use of the management team and/or for tax purposes.

Bookkeeping and Accounting Advice

We provide professional bookkeeping and accounting services for small and medium-sized businesses (SMBs). Our professionals can prepare all the necessary data so that your books contain relevant information and comply with the provisions of all applicable laws. With us, your financial data is in good hands.

If you prefer to keep your own books, our professionals can help you with a broad range of useful advice. The firm can provide training in the use of various accounting applications available for SMBs and non-profit organizations.

Evaluation of Internal Control Systems

Internal control involves all the measures companies take to protect themselves against errors, fraud, and illegal acts. Management is responsible for setting up an effective internal control system.

Our role as chartered professional accountants is to point out any significant weaknesses in your organization's internal control system so management can take the necessary corrective measures. You can rely on our team of professionals to help you detect any problems so you can protect your assets, achieve your business objectives, and ensure your organization's profitability.

Due Diligence

Company mergers and acquisitions involve significant risk. Due diligence is an important process that allows you to identify these risks, understand the true situation of the companies involved, and avoid unpleasant surprises. Marcil Lavallée has a multidisciplinary team that can support your decision making and negotiations. You receive practical advice and useful recommendations that will help you make appropriate strategic choices.

Financial Compliance Auditing

Each year, government ministries and agencies grant large sums of monies to businesses and non-profit organizations in the form of targeted payments governed by contribution agreements between the parties. Contribution agreements contain various financial and non-financial clauses with which recipients must comply. Under the Treasury Board of Canada's Policy on Transfer Payments, agencies and ministries must ensure that the money is used for the intended purposes and the objectives achieved.

The auditor's role is to make sure that receiving organizations comply with the financial and non-financial clauses established between the parties. Marcil Lavallée has a specialized team that audits grant and contribution recipients. Over the years, our professionals have acquired substantial experience in this field.

When you entrust your government contribution and grant audits to us, you benefit from our experience, expertise, and specialized approach that ensures the efficient, reliable handling of your audit.
