An objection is a formal, written disagreement with a CRA assessment, and the format matters.

What this means for you

Most taxpayers only interact with this process once, which is exactly why the timelines and terminology feel unfamiliar. Knowing the shape of the process in advance — what letter comes first, what response window you get, and what happens if you miss it — changes how stressful the experience feels even before anything is resolved.

What you can do next

  • Confirm which tax year and account the notice actually concerns
  • Call the number on the notice itself, not a number found by searching online
  • Write down the name, date, and reference number for every call

Vague objections get returned for clarification, which quietly burns weeks off your window.
