My husband is not a citizen or resident but it says we owe taxes?

As per the Canada Revenue Agency (CRA):

Under the Canadian income tax system, your income tax obligations to Canada are based on your residency status. To determine your residency status for tax purposes, all of the relevant facts in your case must be considered, including residential ties with Canada and the length of time, purpose, intent and continuity of the stay while living inside and outside Canada.

The most important thing to consider when determining your residency status in Canada for income tax purposes is whether or not you maintain or establish significant residential ties with Canada.

Significant residential ties to Canada include:

• a home in Canada
• a spouse or common-law partner in Canada
• dependants in Canada

Secondary residential ties that may be relevant include:

• personal property in Canada, such as a car or furniture
• social ties in Canada, such as memberships in Canadian recreational or religious organizations
• economic ties in Canada, such as Canadian bank accounts or credit cards
• a Canadian driver's licence
• a Canadian passport
• health insurance with a Canadian province or territory

To add to @Heidi123's answer, also if you have spent more 183 days in Canada in a fiscal year, you will be consider resident of Canada.
