How it works

A straightforward filing process

We tell you what is needed, organize the information, prepare the work and confirm the next steps with you.

Tell us your situation

Book an appointment, call, email or WhatsApp the office.

Gather your records

We provide a checklist based on your tax or accounting needs.

Review & prepare

Your information is organized and the applicable filing or accounting work is prepared.

Finalize & follow up

We confirm the result, outstanding items and any next actions that require your attention.

Beyond tax season

Keep your business books ready all year.

Monthly bookkeeping, payroll and GST/HST support can reduce the year-end rush and give you cleaner information to make business decisions.

Year-round services

Accounting should not start the week your return is due.

  • Routine bookkeeping
    Keep bank, credit-card, revenue and expense records organized.
  • Payroll administration
    Track deductions, employer amounts, vacation, bonuses and remittance information.
  • GST/HST cycles
    Stay on top of monthly, quarterly or annual reporting periods.
  • Year-end readiness
    Cleaner books make tax filing and financial review easier.
Common questions

Start with the basics

Can you help if I missed the tax deadline?

Yes. We can help organize and prepare outstanding returns. If tax is owing, penalties or interest may already apply, so it is generally better to address overdue filing sooner rather than later.

Do you work with self-employed clients?

Yes. We assist sole proprietors, contractors and gig workers with business-income reporting, expense records, GST/HST questions and related bookkeeping needs.

Can I work with you remotely?

Remote appointments are available. For confidential tax documents, contact us first so we can confirm the appropriate way to exchange information rather than sending sensitive records through the public website form.

Do you offer bookkeeping and payroll outside tax season?

Yes. Bookkeeping, payroll and business accounting support are year-round services.

What should I bring for a personal tax return?

Your exact list depends on your situation. Start with income slips, tax receipts, CRA correspondence and supporting documents. Use our printable checklist as a guide.
