Yes - U.S. citizens and residents are subject to U.S. federal taxation, irrespective of whether they are working in the U.S. or in a foreign country. So your income earned in Canada will be subject both to U.S. federal and Canadian federal and provincial taxation.
However, there are provisions in the U.S. tax code to mitigate double taxation of income earned by U.S. citizens and residents working abroad - you can qualify for a foreign earned income exclusion under 1 of 2 tests, the Bona Fide Residence Test or the Physical Presence Test, as well as a foreign housing exclusion or deduction, for your Canadian housing costs. You can also take a foreign tax credit for the Canadian taxes paid on your unexcluded income earned in Canada, to the extent it is double taxed both by Canada and the U.S.
TurboTax supports filing Form 2555, Foreign Earned
Income, to calculate your foreign earned income exclusion and foreign
housing exclusion or deduction, as well as Form 1116, Foreign Tax Credit.
The Deluxe,
Premier and Self-Employed versions of TurboTax Online all support Form
2555 and Form 1116 (not Federal Free), as well as all versions of TurboTax
Desktop, for Windows or Mac.
