I can confidently say that they deliver a level of service that goes beyond expectations. From the very beginning, I felt like I was in good hands.

I had my taxes done at Mackisen Consultation Inc., and I couldn’t be more satisfied. The technicians were not only highly skilled but also took the time to explain every detail.

I do my taxes for me and also all members of our family with Mackisen since more than 25 years. They are very reliable and very patient and quick to support and react.

I've been going to Mackisen for over 20 years to do my taxes and for other financial advice. I couldn't be happier with their service, making finance easy to understand.
Our Core Audit & Assurance Services
Financial Statement Audit (IFRS/ASPE)
The gold standard in financial reliability. We conduct independent audits that verify every figure in your financial statements, producing an auditor’s report with full assurance and credibility. Audited financials earn immediate trust from banks, investors, and regulators—enabling smoother financing, mergers, and growth.
Review Engagement (Mission d’examen)
When a full audit isn’t required, a review provides professional credibility at a lower cost. Through analysis and inquiry, we ensure your statements are plausible and accurate, giving lenders moderate assurance and improving borrowing potential.
Compilation (Notice to Reader / Mission de compilation)
Ideal for small businesses seeking clarity and organization. We compile your financial information into professional CPA statements that strengthen loan applications and internal decision-making—even without an audit opinion.
Special Purpose and Compliance Audits
For grants, government funding, or lender covenants, we perform targeted compliance audits. Our reports help you meet the requirements of regulators, boards, and funding agencies with confidence.
Internal Controls and Risk Advisory
Protect assets and reputation with a control audit that identifies weaknesses before they become problems. We review accounting systems, fraud prevention, and IT safeguards to enhance reliability and boost lender confidence.
IFRS/ASPE Conversion and Advisory
Transitioning from ASPE to IFRS or preparing for an IPO, merger, or acquisition? We manage the conversion—from policies to restatements—ensuring compliance and clarity for global investors and partners.
The Mackisen Advantage
Financial statements accepted by major banks and investors
Faster loan and financing approvals
Lower borrowing costs through verified transparency
Stronger confidence from investors and boards
Full compliance with IFRS, ASPE, and Quebec CPA standards
Comprehensive review of internal controls and fraud prevention
