Canada’s framework for compilation engagements is undergoing substantive modernization. In 2021, the long-standing “Notice to Reader” model under Section 9200 of the Canadian accounting standards handbook was replaced by ‘Canadian Standard on Related Services’ (CSRS) 4200, governing compilation engagements involving historical financial information. That change fundamentally reshaped how non-assurance financial statements are prepared and communicated. The evolution has progressed further with the development of proposed CSRS 4250, addressing future-oriented financial information and pro forma reporting.
These changes are not minor drafting refinements. They represent a structural recalibration of Canada’s non-assurance reporting landscape. For the Auditing and Assurance Standards Board (AASB) responsible for their development, the objectives have been clear: closer alignment with international standards, sharper conceptual boundaries between assurance and non-assurance engagements, and strengthened public confidence in the credibility and transparency of financial reporting where no assurance is provided.
As Secretary of the Board of Directors at Registered Professional Accountants of Canada (RPA Canada), I was invited by the AASB to participate in the field testing group for CSRS 4250. The process demonstrated that even non-assurance standards are deliberate, structured, and tested against practical realities. Questions of proportionality, documentation, professional judgment, and clarity are rigorously examined before finalization. Non-assurance does not mean unstructured.
From Notice to Reader to CSRS 4200: Convergence and Clarity
For decades, compilation engagements were governed by Section 9200, commonly known as the “Notice to Reader.” The framework was brief and pragmatic but minimally prescriptive. Documentation requirements were limited, engagement acceptance procedures were loosely defined, and reporting language sometimes left room for misunderstanding about the practitioner’s role.
Globally, the International Auditing and Assurance Standards Board modernized its compilation framework through ISRS 4410 (Revised), introducing clearer acceptance requirements, structured documentation expectations, and enhanced reporting transparency. The AASB concluded that Canada’s model no longer reflected contemporary best practice. CSRS 4200 was therefore developed to substantially converge with ISRS 4410 while adapting it to Canadian practice realities.
CSRS 4200 introduced explicit engagement acceptance and continuance requirements, mandated knowledge of the entity and its accounting system, required documentation of significant professional judgments, and standardized reporting language emphasizing that no assurance is provided. It also requires clear disclosure of the basis of accounting. The result is greater structure without transforming compilations into assurance engagements, reducing the expectation gap while preserving proportionality.
The Next Step: Proposed CSRS 4250
With historical compilations modernized under CSRS 4200, attention turned to forward-looking information. In September 2024, the AASB issued an Exposure Draft of proposed CSRS 4250 to replace the outdated AuG-16 guideline with a stand-alone standard structured consistently with CSRS 4200.
The proposal expressly covers forecasts based on best-estimate assumptions, projections based on hypothetical or combined assumptions, and pro forma financial information presenting the effects of actual or contemplated transactions as if they occurred at a specified date. It refines key definitions, clarifies scope boundaries, and eliminates reliance on cross-referenced guidance, creating a comprehensive framework for forward-looking compilation engagements.
Engagement acceptance is more disciplined, particularly where third-party use is contemplated. Practitioners must inquire about intended use, obtain acknowledgment of the basis of accounting, and ensure that third parties can request additional information or have agreed to the accounting basis applied. These preconditions function as structured gatekeeping safeguards.
Although no assurance is provided, minimum work effort is clearly defined. Practitioners must obtain sufficient knowledge of the entity, its accounting system, and how management developed its assumptions; read the compiled information to consider whether it appears misleading; address concerns with management; and withdraw if necessary. Required note disclosures include the basis of accounting, significant assumptions and their effective date, the intended purpose of projections and pro forma information, and explicit caution that actual results will vary and may be materially different.
The proposal introduces defined documentation requirements and integrates engagement-level quality management consistent with Canadian quality management standards adapted from international models. The prescribed report format clearly identifies the nature of the information, describes management’s responsibilities, disclaims assurance, includes cautionary language, and addresses procedures if material facts become known after issuance.
Proposed CSRS 4250 therefore strengthens structure, transparency, and documentation without converting the engagement into assurance. It represents disciplined non-assurance aligned with the broader modernization of Canadian standards.
Standard Setting, Independence, and the Public Good
The governance context reinforces this modernization. The Independent Review Committee on Standard Setting in Canada (Final Report, March 1, 2023), established by the Accounting Standards Oversight Council and supported by CPA Canada concluded that accounting and assurance standards are a public good. The Committee emphasized that CPA Canada’s role is one of stewardship rather than proprietary ownership and observed that restricting access to standards is inconsistent with their public-interest character.
If standards are public goods stewarded in the public interest, their legitimacy rests on transparency, structure, and governance, not exclusivity. Standards exist to enhance comparability, reliability, and clarity, not to function as instruments of market control.
Ontario’s Model: Public Protection and Competitive Access
Ontario’s legislative framework reflects the same policy orientation underpinning the modernization of compilation standards.
When the Public Accounting Act, 2004 was amended in 2021 following the introduction of CSRS 4200, the government confirmed that subsection 2(3) was intentionally preserved. That provision permits accountants who do not hold an assurance (public accounting) license - including Registered Professional Accountants (RPAs) and Chartered Professional Accountants (CPAs) without such a license - to perform compilation engagements, provided those engagements include an assurance disclaimer and comply with CSRS 4200. The amendments updated statutory references to align with the new reporting model but did not narrow scope of practice.
In 2024, the government reaffirmed that this framework continues to function effectively in serving consumers of accounting services. The statutory distinction remains structural and risk-based: assurance engagements are reserved, while non-assurance compilations operate within a regulated yet inclusive framework across professional designations. Transparency is enhanced while competitive access is preserved.
Professional Regulation and Productivity
In February 2026, the Competition Bureau of Canada commissioned research published in the International Productivity Monitor examining the economic effects of restrictive market regulation in Canada. The study situates professional services - including accounting, law, and engineering - as upstream sectors whose regulatory design influences productivity throughout the broader economy.
Using OECD Product Market Regulation indicators, the study finds that Canada’s framework for professional services - particularly entry requirements, preservation of exclusive rights over certain activities, and business conduct restrictions - is more restrictive than in best-practice OECD jurisdictions. Such regulatory settings can constrain entry, weaken competitive pressures, and impair allocative efficiency, especially in upstream sectors supplying inputs to the broader economy. At the same time, the authors observe that several OECD countries have eased comparable restrictions without evidence of diminished service quality or reliability, suggesting that pro-competitive reform need not compromise public protection. This mirrors Ontario’s positive experience after choosing an inclusive regulation for the delivery of compilation services across multiple qualified service providers, including both CPA and RPA members.
The macroeconomic implications are significant. The study estimates that pro-competitive reforms in upstream sectors, such as professional services, could yield long-run GDP gains in the range of approximately 6.5% to 10%. The mechanism is structural: when upstream professional services operate more efficiently and competitively, downstream sectors benefit from lower input costs, improved access to expertise, and enhanced innovation capacity.
This is not an argument for deregulation. It is an argument for calibration, preserving safeguards where public risk justifies protection while avoiding restrictions that cause inefficiency while not demonstrably enhancing public protection.
Ontario’s legislative model reflects that calibration: structured oversight without exclusivity beyond what risk warrants.
Considered alongside the public-good characterization of standards, the stewardship model of governance, the demonstrated functioning of Ontario’s legislative framework, and the Competition Bureau–commissioned evidence on productivity effects, a coherent policy thread emerges. The modernization of CSRS 4200 and the development of proposed CSRS 4250 fit squarely within that architecture. Rigorous standards and appropriately structured market access are not in tension. When proportionate regulation protects higher-risk assurance services while permitting competitive participation in disciplined non-assurance engagements, the result is enhanced public confidence, improved market functioning, and stronger long-run economic performance.
Conclusion: Structure, Legitimacy, and the Public Interest
Canada’s transition from Section 9200 to CSRS 4200 - and now toward CSRS 4250 - reflects the maturation of non-assurance services. Even where no opinion is expressed, disciplined methodology matters.
Governance reform has clarified that standards are public goods stewarded in the public interest. Provincial legislation demonstrates that public protection and inclusive participation can coexist. Economic research underscores that balanced professional regulation can strengthen productivity without undermining quality.
A coherent framework therefore requires clear professional standards, transparent reporting, legislative protection for assurance engagements, and competitive access in structured non-assurance services. In this context, public protection and competition are not opposing principles. Properly designed, they reinforce one another.
