Would suggest talking to other music teachers in Canada. Not sure where you are from in the US but your cost of living may have been lower in the US while salaries are also likely to be lower in Canada. The private music teachers I have known would not have considered their jobs as lucrative and any self employed person doesn’t hav3 the benefit of benefit plans, retirement savings or even access to unemployment. Access to unemployment may now change. Would be looking into your various costs. Real estate costs, insurance, telecom, utility costs, childcare, taxes (although you can set up your own business and pay yourself the minimum amount necessary to save taxes), etc. can be surprising to many coming from certain US states.
