COVID-19 Update

Effective immediately, Deverdenne Davis Cyr LLP will operate in an electronic environment only. We will no longer be accepting paper documents.

For the safety of our clients and the Grande Prairie community, we have made the decision to close the office and work remotely.

We are fortunate to have the ability to process your accounting and taxation needs electronically. We ask that you provide all documents for your personal taxes and corporate year-ends via FileShare on our website.

FileShare is a secure way to submit documents and files to our office. Documents are encrypted and there are no size restrictions on files. Simply click on the link, enter your name, a brief message and add files or drag and drop your files, then click upload.

Our phone lines continue to be fully functional, so please call reception at 780-814-7474 if you require additional assistance.

If you prefer to submit using regular email, we encourage you to password protect your documents as an added precaution. Please call reception at 780-814-7474 with your chosen password.

Once complete, your final package will be delivered to you electronically.

Your business, your health and the health of our team members are of utmost importance to us. We will strive to meet your needs with limited disruption during this time of uncertainty.
