Getting Ready for an Audit: A Canadian Company’s Guide

Audits don’t have to be something you dread. At their best, they give your stakeholders confidence in your numbers and provide management with valuable insights into how processes can improve. The key is preparation. By getting organized before the auditors arrive, you can keep the process on track, avoid unnecessary delays, and make audit season a lot less stressful.

This guide walks through what Canadian companies can do to be audit-ready, whether you’re a private business reporting under Accounting Standards for Private Enterprises (ASPE) or a public company following International Financial Reporting Standards (IFRS).

Align on scope, framework, and timelines

Start with a quick alignment: confirm the financial reporting framework, any new standards or policies, the entities in scope, and key dates. Finalize your engagement letter, schedule a kick-off meeting, and ask for a prepared-by-client (PBC) list early. If you have significant changes this year, such as acquisitions, a new revenue stream, or a system change, flag them at kick-off so audit procedures and timelines reflect reality.

It’s also best to communicate with your auditor throughout the year if large transactions take place, so plans can be made to address them promptly and appropriately during the audit.

Close the books cleanly

A clean close is the fastest way to a smooth audit. Reconcile bank accounts, payables, receivables, and payroll subledgers to the general ledger. Tie the trial balance to your working papers, and resolve suspense and clearing accounts. Document cutoff procedures, especially around year-end sales, purchasing, and cash receipts.

Aim to get all post-closing adjustments posted early to avoid confusion and inefficiency later. Consider whether any journal entries are needed for non-routine or significant transactions to ensure your books accurately reflect your operations before the auditors arrive.

Organize the documents auditors always ask for

Most PBC lists follow a familiar pattern. Having these ready saves days:

• Corporate documents, recent board and committee minutes, and key contracts
• Bank statements and reconciliations, debt agreements, covenant calculations
• Accounts receivable and accounts payable aging reports, credit notes, significant customer and supplier terms
• Revenue and purchasing support, including master service agreements, statements of work, and side letters
• Inventory listings, costing methodology, and recent physical count results
• Property and equipment schedules, additions, disposals, and support for impairment assessments
• Lease schedules and calculations, especially for IFRS 16 or ASPE lease guidance
• Share-based payment schedules, option plans, and valuation support
• Payroll summaries, remittances, and bonus or commission plans
• Legal letters, insurance summaries, and claims tracking
• A list of related parties and related-party transactions
• Subsequent events review

Keep supporting documentation in order—such as invoices, receipts, expense reports, purchase orders, sales invoices, shipping documents, and payment approvals. Prepare memos for key or significant transactions during the year, analyze the accounting treatment, and discuss them with your auditor ahead of time to avoid surprises.

Keep everything in a secure shared location, name files consistently, and avoid duplicates. One well-maintained index can save more time than any status meeting.

Document your key processes and controls

Audits test more than numbers—they also assess how those numbers are generated. Short process narratives or simple flowcharts for revenue, purchasing, payroll, inventory, treasury, and financial close help auditors understand where data originates, who approves it, and how changes are controlled.

Note the system of record for each process, key reports used, user access controls, and any manual workarounds. You can also ask your auditor for a sample template or guide on how to document these processes. Right-sized documentation is fine as long as it’s current and reflects how the team actually works.

Plan for inventory counts and other field procedures

If you hold inventory or valuable physical assets, align early on timing for counts and site visits. Ensure count instructions are clear, tickets are pre-numbered, obsolete or damaged items are flagged, and third-party locations are covered. For project-based or construction businesses, prepare progress-billing and work-in-process support. Early coordination here prevents last-minute scrambles that ripple through the entire audit.

Get ahead of revenue and significant estimates

Revenue and estimates drive many audit questions. Make sure your accounting policy memos are current and match how you run the business. Under IFRS this often means documenting performance obligations, variable consideration, and principal versus agent conclusions. Under ASPE, focus on recognition criteria, measurement, and collectability.

For estimates such as impairment, expected credit losses, decommissioning obligations, fair values, and share-based payments, provide methods, key assumptions, and sensitivity analyses. Clear management documentation shortens the review cycle and demonstrates preparedness.

Assemble the right audit-season team

Designate one internal project lead who owns the PBC list, coordinates responses, and tracks status. Identify process owners for revenue, purchasing, payroll, and inventory, and agree on response times during fieldwork.

Your external team typically includes auditors, legal counsel, securities counsel if you are public, or a transfer agent. Add a financial reporting team or consultants who can help with IFRS conversions, complex transactions, and drafting disclosures. When roles are clear, questions get answered once, not five times.

Public company considerations, at a glance

Publically traded companies operate on a tighter cadence and face additional governance and certification requirements. Private enterprises can adopt many of the same disciplines, scaled to fit their operations.

• Governance and oversight: Public companies have a board-level audit committee that oversees external reporting. Private companies can mirror this with a finance committee or periodic advisory check-ins to improve accountability and speed decisions.
• Controls and certifications: Public company Chief Executive Officers (CEOs) and Chief Financial Officers (CFOs) certify disclosure controls and internal control over financial reporting each period. Private companies benefit from lighter documentation but can still gain from defined approvals, access controls, and close checklists.
• Reporting cadence: Public companies follow a fixed schedule for interim and annual filings, plus continuous disclosure. Private companies can adopt a similar calendar to reduce fire drills and make audit timing predictable.
• Complex accounting: Public issuers more often face areas like business combinations, fair value, and share-based payments. Private enterprises encounter these too, so capturing assumptions and methods is always good practice.

Set up audit week for success

Agree on a daily or weekly check-in, who attends, and how questions are routed. Use one tracker for requests, responses, and outstanding items. Provide sample selections promptly, and bundle support in a single PDF or folder per sample so nothing is missed. Keep a short list of decisions and open judgments that need executive input.

At the end of fieldwork, align on proposed adjustments, disclosure enhancements, and follow-ups. Schedule the management representation letter review early to avoid last-minute surprises, and coordinate with your auditor on timing for completion and what documents need to be signed and by whom.

A smoother audit, year after year

The most efficient audits are built on habits, not heroics. Close the books cleanly, keep documentation current, rehearse your calendar, and give your team and auditors a single source of truth. Whether you’re a private company looking to minimize disruptions or a public company preparing for a busy filing cycle, these steps turn the audit from a deadline into a value-add.
