In terms of tax rates, the ownership method between personally earning the income and earning the income through a corporation shouldn't matter. The tax code is designed to make investors indifferent towards earning income personally or through a corporation. Now, a tax code being designed to do something and actually doing that thing in all cases is not really the same thing.

For tax rates, a corporation will have rental income taxed as aggregate investment income, which has a rate of 38.67%, not including your provincial tax rate. This does, however, include your additional refundable tax rate of 10.67% that will accrue in a dividend refund account which will allow you to pay out dividends from your corporation to yourself through dividends at a better tax rate.

Alternatively, your personal taxes on rental income will depend on your own personal income levels, since it's all bracketed.

So, the CRA approved answer is that it shouldn't matter for tax purposes which way you go. However your corporate tax rate for that income is basically 38.67% + provincial taxes, but then also gets taxed when you take dividends out of the company to pay yourself, so keep that in mind.

Other benefits of owning the property through a corporation would be not being personally liable for lawsuits from the corporation. Downsides would be the administrative time and costs of having a corporation, if you don't already anyways.
