Questions

Do you do both the corporation and the owner's personal return?

Yes. We usually prepare the T2 and the family's T1s together, so salary, dividends and personal credits are planned as one.

Can you deal with the CRA for me?

Yes. Once you authorize us as your representative, we answer CRA notices, reviews and requests for information for you.

Do you work in QuickBooks?

Yes, QuickBooks Online if you already use it, and we can set it up. Most of our clients' books are kept in Excel, which costs nothing in software. Either way, a person reviews every reconciliation.

How do I send my documents safely?

Through Intuit Link, our secure client portal. Request an invitation on our upload page and we send one, usually the same business day. Please don't email your SIN, banking details or ID.

Do I need to come into the office?

No. Most of our work is done remotely, for clients across Canada. Call or email if you'd like to meet at the Mississauga office.

How do I pay?

By Interac e-Transfer. The details are on the Pay an invoice page.
