Investment income, other than capital gains, is considered property income. What would normally be classed as capital gains can be considered to be business income.
Rental income can be considered property income, but rental income can also be classed as business income.
When a loss from property exceeds income from other sources and cannot be deducted on the current year tax return, it becomes a non-capital loss, and can be carried back to the previous 3 taxation years, or forward up to 20 taxation years.
When the use of property changes from income-producing to non-income-producing (i.e., personal use) or when it changes from personal use (non-income-producing) to income-producing, there is a deemed disposal of the property. Regarding real estate properties, see Change in Use of Real Estate. These rules apply to rental properties and principal residences, as well as 2nd homes that are not income-producing.
