Evidence before entry: Evaluating the college of psychologists and behaviour analysts of Ontario’s regulation modernization proposals.

This commentary critically examines the proposed regulatory changes by the College of Psychologists and Behaviour Analysts of Ontario to modernize entry-to-practice standards for psychologists and psychological associates in the province.The analysis places Ontario's changing regulatory environment within the broader Canadian context, comparing provincial standards, training pathways, and workforce availability.Using empirical data, stakeholder feedback, and consensus reports, this commentary examines evidence to test three implied hypotheses of the proposed changes: (a) They will increase the number of psychologists in Ontario, (b) they will improve access to mental health services, and (c) they will not elevate risk to public safety or reduce practitioner competence.Findings suggest that lowering entry standards and shifting from external accreditation to a college-approved process are unlikely to significantly increase access to mental health care.Evidence does not support the view that competence will remain unchanged among trainees from programs that substantially deviate from accredited models.Removing external evaluative safeguards may increase the likelihood that some less-prepared individuals enter independent practice.An evidencebased, data-driven approach grounded in transparent consultation and continuous evaluation is recommended to ensure that regulatory changes genuinely improve access to competent psychological care across both Ontario and Canada. Public Significance StatementMajor changes are happening in how psychologists and psychological associates are regulated in Ontario.This will have important effects on the future of professional psychology both in Ontario and other provinces.Making sure that decisions about these changes are based on the best available evidence is crucial for safeguarding public safety, ensuring the competence of licensed professionals, and improving access to psychological care.
