Support for veterans in Canada runs through federal programs rather than municipal tax relief. A disability pension administered through Veterans Affairs Canada is non-taxable income, and that federal benefit is the closest equivalent to what a US-style veteran exemption is trying to describe.
A Stonebridge veteran weighing a move can still use the ordinary tools available to any Saskatoon homeowner: an assessment check against the Saskatchewan Assessment Management Agency's roll, and a Board of Revision appeal if the recorded details are wrong, neither of which depends on military service.
If you are a Stonebridge veteran planning a sale, what matters most is an accurate market number, not a search for a program that does not exist. Get your hand-reviewed valuation from Joel Dyck.
