New CMLTO By-Law
23 December 2022
The CMLTO Consolidated By-Laws came into effect on December 31, 1994 and underwent many amendments since then to ensure that they remained consistent with legislation.
Based on external and internal consultation and a comprehensive review of the CMLTO Consolidated By-Laws in March 2022, CMLTO undertook a fundamental rewrite of the By-Laws.
The new CMLTO By-Law has been developed pursuant to Section 94 (1) of the Health Professions Procedural Code, being Schedule 2 of the Regulated Health Professions Act, 1991 by taking into consideration the following reference documents:
1. Current Legislation,
2. Ministry of Health – College Performance Management Framework (CPMF),
3. By-Laws of 25 Health Regulatory Colleges, and
4. CMLTO Governance Documents.
At its September meeting, the CMLTO Board of Directors approved the New CMLTO By-Law in principle, for circulation to Registrants for a minimum of sixty (60) days pursuant to Section 94 (2) of the Health Professions Procedural Code.
The New CMLTO By-Law was circulated to Registrants on September 22, 2022 for consultation for sixty (60) days. All feedback received as a result of this consultation has been compiled and presented to the Board of Directors prior to its final deliberations in December.
At its meeting on December 1, 2022, the Board of Directors revoked the CMLTO Consolidated By-Laws and all previous by-laws relating to the administration of the affairs of the CMLTO and approved the New CMLTO By-Law.
The New CMLTO By-Law can be accessed here.

Equity, Diversity, Inclusion, and Justice: Where We Stand
13 December 2022
Equity, Diversity, Inclusion and Justice
Recognizing the significant impact of equity, diversity, inclusion and justice matters in our society and the potential for impacts and implications for all Boards of Directors, including those in the health regulatory sector, the CMLTO Board of Directors has set the following goal:
“To begin, together as a Board, the learning process around Equity, Diversity, Inclusion and Justice matters including the issues/concerns, the impact and action needed by the Board, and the related influence/direction the Board wishes to have on CMLTO as an organization.”
The CMLTO Board of Directors embedded this in its work and planning for 2022 and beyond to further understand these important concepts and the resulting values which should become part of CMLTO’s core beliefs, organizational DNA, and way of doing business.
As a direct result of their work on these important topics this year, the Board approved an Equity, Diversity, Inclusion and Justice Plan, which can be found here.
An action plan based on the Board’s principles will be established in 2023 to advance the Board’s focus. This plan will be released publicly as it is developed and approved to ensure that the public, registrants and all stakeholders understand the Board’s direction transparently.
Feedback regarding the CMLTO Board of Director’s equity, diversity, inclusion and justice principles, and plan are welcome from the public, registrants and stakeholders at any time.
