What is APGO?
The Professional Geoscientists Act, 2000 received Royal Assent on June 23, 2000 and established the Association of Professional Geoscientists of Ontario (APGO). APGO governs the practice of professional geoscience in Ontario and reports to the Minister of Northern Development and Mines. The legislation protects the public and investors by establishing a regulated association of geoscientists with the power to admit only qualified persons, to encourage continuing professional competence, to discipline members for professional misconduct, and to prevent unqualified individuals from practising.


The Act defines a professional geoscientist as someone who performs any activity that requires the knowledge, understanding and application of the principles of geoscience, and that concerns the safeguarding of the welfare of the public, life, health or property, including the natural environment, and who meets the requirements of membership in the APGO.

To understand more about this definition and how it applies, please refer to the pamphlet 'Interpretations, Explanations and Selected Examples of "Professional Geoscience" As Defined in the Professional Geoscientists Act, 2000'
