Audit and advisory in Toronto
Black Maple provides partner-led assurance services for growing businesses, subsidiaries, and cross-border groups.
Let's talkAbout
Toronto is the head office of Black Maple Professional Corporation, our Public Accounting License holder in Ontario. From the 130 King Street West office, we run statutory audits and reviews for private companies, TSX and TSX-V issuers and cross-border subsidiaries, alongside advisory, fractional CFO and sustainability reporting work.
The Toronto practice is partner-led on every file, with no offshored junior teams. We are typically called by mid-market businesses that have outgrown a sole-practitioner audit but do not need a Big Four logo on the auditor's report, and by TSX and TSX-V issuers who need an auditor who already knows section 3061, flow-through share renunciation and going concern at exploration stage.

Most Canadian conversations start here. The right level of assurance depends on who reads your financial statements and what they decide on the strength of them, not on the size of your organisation alone.
| Criterion | Audit (CAS) | Review engagement (CSRE 2400) | Neither |
|---|---|---|---|
| Level of assurance | Reasonable. A positive opinion that the statements present fairly. | Limited. A negative conclusion: nothing has come to our attention. | None. Statements are prepared but not independently examined. |
| What we do | Substantive testing, confirmations, an understanding of internal control, and evidence gathered across the whole balance sheet. | Inquiry and analytical procedures, with specific work on estimates, related parties, going concern and fraud risk. | Preparation and compilation only. |
| Typically required by | Statute, securities regulators, lenders on larger facilities, government funders, and buyers in a transaction. | Boards, smaller lending facilities, and members who have stepped down from an audit by resolution. | Nobody external. A management and tax filing exercise. |
| Relative cost | Highest | Materially lower | Lowest |
| Best when | You are a reporting issuer, transacting, raising money, or have real estimation risk. | You want independent eyes and a proportionate fee, and nothing in law or contract demands more. | You are small, unregulated, and no third party relies on the numbers. |
Reporting issuers listed on the TSX or TSX-V require an audit under securities law, with no proportionality argument available. For private companies the choice is usually driven by lending covenants and shareholder agreements rather than statute.
