To our valued current and future clients The current COVID-19 crisis has created a challenge that none of us could imagine just a short time ago.

Client Testimonial: "Thank you both, you and Wendy, for all your care on our file.

Your family is the answer to our prayers. Your family and the jobs you chose certainly fill a great need in our society. A society built on the backs of many unskilled/uneducated hard working family oriented people unfamiliar to tax laws and policies.

We will definitely pass your families’ name on to anyone we know being audited. If that is okay. Even though we have never meet your family, you have treated us with respect and dignity, cared about what we had to say… like a father and mother would and we appreciate that so much. Thank you from the bottom of our hearts. I write this email barely able to see the words written as the tears spill over in joy and gratitude to you!!" Click here to read more testimonials.

Cawston and Associates has been involved in taxation for over 40 years. Our background includes audit representation, voluntary disclosures, collections, assessments, appeals, bankruptcy representation, and taxpayer relief.

Head partner William Cawston spent 8 years at the Canada Revenue Agency. During this time he was involved in auditing, collections, assessments, and eventually was promoted to Chief of Taxroll.

William left the CRA to become a small business owner but after many years of good and bad times he decided his true passion was in tax. In 2007 his son Trevor Cawston joined the practice bringing with him practical bankruptcy solutions and corporate administration services.

Cawston and Associates works with accountants, bookkeepers, lawyers, and the Canada Revenue Agency to ensure that you have the most cost effective solutions to your tax problems. Due to our high level of knowledge of tax law and CRA policy we have an extremely high success rate in appeals, and taxpayer relief.

Calgary Tax Accountants and Tax Consultants, What We Do:

As Calgary tax consultants we handle tax issues such as non-filers, which are people who have not filed tax returns and may or may not be prosecuted by CRA.

  • We do monthly monitoring of these accounts to ensure that our clients remain compliant.As tax consultants we specialize in defending taxpayers against Director’s Liability assessments and against Section 160 transfer of assets.
