Audit fees keep going up. Here's how to push back.

Across the Canadian mid-cap and junior-issuer cohort, year-over-year audit-fee increases of 30–50% have become common, with sharper jumps for issuers in CPAB-priority sectors (mining, cannabis, crypto, complex revenue recognition) and for first-year audits after a firm change. The drivers are stacked: CAS 315 Revised and CAS 540 Revised scope expansion, CPAB inspection follow-through, fewer firms competing for the work, and audit-firm staff-cost inflation. Comparing your fee to a published benchmark is hard because Canadian audit fees are not centrally disclosed the way they are in some other jurisdictions — peer cohort data inside readiness platforms is one of the few useful reference points.

Sometimes — but rarely as cleanly as people hope. First-year audits carry a real premium because the new firm has to perform opening-balance procedures, document its understanding of the entity from scratch, and re-do risk assessment without the prior file. Rule 204 of the CPA Code of Professional Conduct constrains who you can engage where independence is in play. There are also disclosure obligations around auditor change in your continuous disclosure record. A re-bid against credible CPAB-registered mid-tier firms is almost always worthwhile as competitive pressure — but treat rotation itself as a multi-year decision, not a one-year fee tactic.

It varies dramatically by complexity, sector, and stage. A pre-revenue resource-exploration issuer with a clean structure may sit in a lower band; a multi-jurisdiction issuer with complex capitalized costs, share-based comp, derivatives, going-concern questions, or a recent reverse-takeover can be a multiple of that. The honest answer is that 'expect' is the wrong frame — what matters more is whether the fee is appropriate to your specific scope, and whether it's been padded by the firm's response to last year's rework. Pulling the prior-year engagement letter, comparing the original quote to the final invoice, and identifying the rework variance is more productive than chasing a benchmark number.

Overruns happen on a large share of Canadian public-company engagements, and they almost always trace to the same handful of issues: late or missing reconciliations, confirmations that bounced or arrived past the cut-off, ICFR walkthroughs that had to be reconstructed during fieldwork, MD&A inconsistencies caught late, or repeat findings from the prior year. The engagement letter usually contains a scope-change clause that lets the firm bill above the quoted fee with documentation. Pushing back on overrun invoices is much harder than preventing them. The right time to control the fee is before fieldwork begins.

It depends on the engagement, and any platform promising a guaranteed dollar figure is overpromising. Industry observers commonly estimate the rework bucket at 15–30% of total audit fees in mid-cap and junior-issuer engagements, but the recoverable share within that varies with how messy the file was to start with, how disciplined the close already is, and whether prior-year management-letter items were already closed out. A clean file with experienced controllers will see less impact than a file that has been carrying repeat findings for two cycles. The right way to size it for your engagement is to compare last year's quoted fee to last year's final invoice — that delta is the variable that pre-audit readiness is designed to compress.

Spreadsheet-based pre-audit workflows have two structural limits. First, they don't carry the standards mapping — a missing reconciliation in a spreadsheet checklist is just a tick box, not a citation back to CAS 315 Revised paragraph 26 or to the specific NI requirement. Auditors and audit committees can't audit the checklist itself. Second, they don't benchmark against a peer cohort: you can't tell whether your readiness score is normal for a TSX-V junior or below it. A platform that maps every checklist item to a standard paragraph and benchmarks the file against comparable engagements addresses both gaps.
