Debbie and her team are hands down THE BEST!!! After having 3 other accounting nightmares Debbie has helped above and beyond!! Knowing Debbie is taking care of our stuff has really relieved our stress. She explains things so we can understand exactly what is happening. We never leave scratching our heads. If you want your stuff taken care of properly, call Debbie and her team.

For the last five years Debbie has been tending to year end taxes for my wife and I. She and her staff have always been attentive, considerate and helpful. Last year when we attended her for our tax briefing she noticed that I had some mobility issues and she inquired if I was experiencing an acute or a chronic problem. I said it had been going on for some time and she suggested that we should make application to the CRA for long term disability consideration.
This year we did just that and were granted a refund accumulating a total of nine years of tax reassessments. This was a most unexpected bonus. Going forward, we will now be entitled to additional relief on our yearly assessments
Thank you, Debbie, for your advocacy.

Debbie has been the accountant for my parents personally and professionally for years and they have always been thrilled with her work. As a young professional there was only one obvious choice of accountant for me. I live six hours away but that has never affected her excellent service. She is the only accountant I will ever use. Thank you Debbie for your amazing work!
