You're supported through the response
No obligation
What happens after you reach out
No obligation. The first call is to understand the issue — nothing more.
You send a confidential note
Tell us what is happening and any CRA deadline. Nothing is filed with CRA, and your details stay with our team.
We reply within one business day
We review what you have shared and come back to you personally to arrange a short call.

We talk through the issue, the deadline, and your practical options — so you know where you stand before deciding anything.
Before you call
Questions owners ask us first
I just got a CRA letter — what should I do first?
Read it carefully and note any deadline, but don't respond in panic. Gather the records you already have. A CPA can help you understand what CRA is actually asking for and organize a proper, on-time response.
Is my information kept confidential?
Yes. Reaching out is confidential, nothing is filed with CRA from an inquiry, and your details stay between you and our team.
What happens on the first call?
It's a short, no-obligation conversation to understand the issue, any deadline, and your practical options. There's no commitment to proceed.
Do you work with businesses outside the GTA?
Yes. We work with owner-managed businesses across Canada, with a presence in Mississauga and the Greater Toronto Area.
Do I need a lawyer or a CPA?
Most CRA audit and tax matters are CPA-led. Where legal advice or legal representation is required, we coordinate with qualified counsel.
What does this cost?
Engagements are scoped after a confidential call, once we understand the issue and what's involved — so any work is agreed in writing before it begins. There are no public price lists for matters like these.
