Okay, let’s tackle this. So Mario has 27 years of experience as a tax professional, which is a significant amount of time. He has worked for the Canada Revenue Agency and the Province of Ontario, which are both reputable organizations. His skills include auditing, tax, financial reporting, and financial accounting. These are all in-demand skills, especially in the public sector. However, his experience is mostly in Canada, which might limit his earning potential compared to professionals working in the US or other countries. Considering his experience, skills, and location, I estimate his hourly rate to be around $125, which is below average for a tax professional with his experience in Canada.
