Bernadette has a high-paying job and is in the top tax bracket.

Dividends from a large public Canadian corporation are eligible for the dividend tax credit, which reduces the amount of tax payable on this type of income. The dividend tax credit is a non-refundable tax credit that recognizes that dividends are paid out of income that has already been taxed at the corporate level, and therefore should not be taxed again at the personal level. The dividend tax credit applies to both federal and provincial taxes, and the rates vary depending on the province or territory of residence12
