Contact Information

Our firm has a long history of providing partner-led accounting and business-consulting solutions to private, public, and non-profit organizations in Eastern Ontario and Western Quebec. We have in-depth experience that spans various industry sectors including manufacturing, retail, construction, service, technology, petroleum, health care, education, and transportation.

Changing to meet our client's needs

We started in 1963 as a two-partner CA firm and have grown into a 12 partner, multi-disciplined professional service organization. Along the way we've operated under different names. Today, we are part of the Collins Barrow co-operative, a national association of independent Canadian firms. Why the changes? To ensure we continue to meet our clients' evolving needs and the challenges of an ever-changing business climate.

Our approach

Clients turn to us because they want hands-on partner involvement, practical tax strategies that save, reduce or defer all forms of taxation, and strategic consultation to help plan, organize, and effectively manage their organization.

Core competencies: tax and accounting services

We've built our firm not forgetting our roots. Our services and reputation have been built on a solid foundation of core competencies: tax, accounting, and assurance expertise. Services are now delivered through six highly specialized practice areas: tax, accounting and assurance, business advisory, litigation support, insolvency and debt restructuring, and government consulting.

See why Collins Barrow should be your firm of choice for tax, accounting, and business advisory services. Let's get together to see how we can help you.
