Questions regarding my Notice of Assessment

Your Notice of Assessment from the CRA actually informs you of an assessment of two income taxes, Federal and provincial/territorial (other than Quebec). There are two independent calculations of these taxes within your income tax and benefit return.

You paid EI premiums and they are allowed in the calculation of non-refundable credits against both Federal and Ontario income tax. That's all they are saying in the first item you quoted. You got a credit against federal tax and Ontario tax.

Ontario has also introduced a new Ontario Health Premium for 2004 -->. This premium is also calculated by reference to the level of your income and is assessed along with your Ontario Income tax. It actualy is a form of income tax. It is authorized within the Ontario Income Tax Act.
