"We were months behind in our bookkeeping and GST/HST and GCA was hired to bring us up to date. Not only did they keep up with our monthly bookkeeping including providing paystubs and source deduction information, but they worked with our corporate accountant for our year-end, prepared and filed our employees T4s and T4As and met with us to explain our financial statements in detail. They are very experienced in their work and highly recommend them!"

" I have had the pleasure of working with GCA Services since inception and I would highly recommend their services to anyone. They are very professional, extremely punctual with dates and timelines and are overall lovely to work with. It is important to trust the folks that manage your finances and I know I can trust them completely. I am a sole proprietorship and need help managing my taxes in both USD and CAD and this is a non-issue for the GCA team. They send me notifications regularly so that I never fall behind with my personal and business taxes. I have already recommended GCA services to my friends and family who are looking for any financial assistance. Their turn around is very fast and their rates are affordable. I look forward to working with them for years to come. Big thanks to the GCA Team. "

"GCA has provided relief to me as a small business owner. Not only do they take care of our monthly bookkeeping and GST/HST filing as well as provide our employees paystubs and T4s and advice on payroll related information, but they have assisted in a GST/HST examination and took care of the CRA agent’s requests; something that would have caused me a great deal of discomfort and stress. Monthly bookkeeping is worth our piece of mind. Highly recommended.
