Gary is an accountant you can depend on to get your taxes and finances done right.

Someone, such as myself, who has experience in the finance and accounting field, and who's worked with accountants, I can say that Gary is very professional and good at what he does. I highly recommend having your taxes and any financial needs done with Gary.

Gary advocates that the two certainties of human existence are death and taxes. Gary’s influence on me has been remarkable. While in my car last week, my infotainment system suggested that I listen to a podcast called “Death & Taxes” while driving; otherwise I am motivated to get my bookkeeping organized. This is a small miracle and one which encourages me to stay current instead of falling behind every year. Thank you for being a part of my life Gary!

I have had the best experience possible with this firm. Especially Gary van der Westhuizen. I have been struggling with CRA for 2 years to have a GST/HST payment refunded to me that was in Tax Limbo, due to an error that was directed by a CRA representative when I first started to file. As any sort of math or accounting is so beyond me, I was terribly frustrated with any assistance that I was getting from CRA. Gary was promote professional and relentless in having this matter resolved. I can't thank him and his firm enough for their support. I would highly recommend them to anyone needing a professional accounting firm to represent them. Especially if you are over 60. ( we are not the sharpest tack in the box when it comes to computers)

I usually don't write reviews, but I have to say that Gary has been extremely wonderful to work with. I emailed him with some concerns around my taxes and he was very responsive and followed through with everything he said he was going to. He wasn't even the one who did my taxes but is continuing to help me resolve the issues that came up since my taxes were submitted. Thank you so much Gary.

We have a Registered Massage Therapy Studio and Gary at Cornerstone has been so amazing helping us every step of the way. He is understanding and non judgemental!!!!!! We recommend his services 100%, we don't know what we would do with out him. You are a life saver! THANK YOU GARY!

Gary is not the average, dry, numbers-only accountant type. He is a caring and compassionate professional who not only will get your taxes and numbers in order, he will help you manage your business so that you are financially sound. If you want your information done right so that it will hold up to scrutiny, he's your man.

Gary has been a huge help to me, my clients and my family members. He's a wealth of knowledge and resources (and has an incredible sense of humor). Thank you for all your help and continued service!
