Over the years, we have built a strong, agile and efficient team to serve the communities in which we operate. Our three practices, in Bonnyville, Cold Lake and Edmonton, have evolved along with the economies of the towns and city in which we operate. We’ve also  weathered several boom and bust cycles, helping our clients survive through the lean times and, conversely, reap the benefits of strong market up-cycles. Today, we are truly a practice equipped to serve all stages of a business’s lifecycle—start up, growth, maturity and succession. Catering to two close, but distinct communities in Northern Alberta, we operate branch offices in Bonnyville and Cold Lake, respectively. Our third office, a well-respected Edmonton practice with a history dating back to 1982 is central to our overall practice. It enables us to work with tax and corporate lawyers, insurance providers, and other specialists to more holistically serve new and existing clients across all of Alberta’s economic sectors.


Founded in 1979, our original branch in Bonnyville has strong oilfield roots. To meet the needs of our local clients, our branch professionals have a pronounced expertise in oilfield services, industrial, and commercial industries. In 2014, we opened a new and larger Bonnyville office to allow for the continued growth of our operation and accommodate our expanding complement of professional staff.

Opened in 2002, our Cold Lake office was initially created as a satellite office of our Bonnyville practice. As the Ross & Sylvestre client base grew, we continued to expand our Cold Lake base and, in 2006, it became an official branch of Ross & Sylvestre. Staffed with a number of accounting professionals, you can expect to receive the same knowledgeable and expert service as you would in Bonnyville. Catering to local industry, the Cold Lake team specializes in retail operations, construction, oilfield contracting and professional services.

Effective January 22nd, 2019, we are pleased to serve our Edmonton clients from our new office space in the Allendale Professional Centre. Our Edmonton practice is focused on expertly serving the needs of small- and medium-sized, and owner-managed businesses. Located in Alberta’s capital, our Edmonton office staff also has a good understanding of the public sector’s tax and regulatory obligation, helping government and public service bodies with their accounting needs. The office is also Ross & Sylvestre’s link to other professionals—tax and corporate lawyers, insurance providers and others—as we work together to complete more complex transactions.
