Our Office Environment
ONBusiness is proud to be a division of Gauvreau Accounting Tax Law Advisory, a fast-growing professional services firm with more than 200 team members nationwide. While our reach extends across Canada, our roots run deep in Manitoba. Headquartered in Winnipeg, with two locations and a fully operational satellite office in Steinbach, our local team of 40+ professionals is committed to serving clients and supporting one another in achieving success.
We’ve cultivated a relaxed, family-oriented office culture that blends small-firm familiarity with the resources and expertise of a national organization. Our student support reflects this balance — offering flexibility, hands-on mentorship from senior team members, and daily collaboration across all levels of the team. Senior management stays actively engaged, ensuring every student has direct guidance and visibility as they progress in their careers.
At ONBusiness, you won’t be stuck behind the scenes. We believe in building client relationships at every staff level, creating opportunities for our team to directly experience the impact of their work on the businesses we serve.
With a diverse client base, strong relationships, and an open office environment, ONBusiness provides an ideal learning ground for future CPAs. Our flexible support structure is designed to help students thrive as they progress through the CPA Professional Education Program, while contributing meaningfully to the success of our clients.
Our Client Base
As a division of Gauvreau , we proudly serve thousands of entrepreneurs nationwide, helping business owners and organizations maximize their impact through accounting, tax, advisory, and legal services.
As part of this network, ONBusiness brings a distinct Manitoba focus — serving entrepreneurs, professionals, corporations, and not-for-profit organizations throughout Winnipeg, Steinbach, and Southern Manitoba. This unique blend of national resources and local expertise ensures that our clients benefit from the strength of a large firm, while maintaining the accessibility and personal connection of a regional office.
For our team, this means exposure to a diverse range of industries and business structures, offering invaluable hands-on experience. Whether guiding start-ups, supporting family-owned companies, or advising established organizations, every engagement creates opportunities for growth, impact, and meaningful client relationships.
Student Experience & Support
At ONBusiness, we believe that developing future CPAs means more than just providing a desk and a deadline — it’s about building confidence, creating opportunities, and investing in your growth.
Every student is paired with a mentor for guidance, but the support doesn’t stop there. Our collaborative culture means you’re encouraged to seek advice from any team member — from peers to senior leaders — ensuring you’re never navigating challenges alone.
We back this with tangible support for your CPA journey.
By blending ONBusiness’s close-knit environment with Gauvreau’s national resources, our students gain both the personal attention of a local team and the breadth of experience from a fast-growing national firm — the best of both worlds.
Future Opportunities
At ONBusiness, the future isn’t something you wait for — it’s something you build. Our rapid growth creates opportunities for advancement at every stage, and we’re committed to ensuring our students and professionals don’t just keep pace, but thrive. With mentorship, diverse client exposure, and the backing of Gauvreau’s national platform, our team members are able to accelerate their careers and step confidently into senior roles.
Our unique approach to client relationships and service delivery means you’ll develop the skills, confidence, and credibility to establish yourself as a trusted professional within the business community — faster than you might expect.
Flexible Employment
We know that life doesn’t begin and end at the office. That’s why we’ve built flexibility into the way we work — from hybrid schedules and flex time, to tailored arrangements for students completing their university studies.
Our goal is simple: to help every team member succeed professionally without sacrificing the things that matter most personally. By supporting balance, we empower our people to show up at their best — both for our clients and for themselves.
