The proposed change under discussion targets a higher inclusion rate on gains above a threshold, and it is aimed at secondary properties, rentals and investment real estate, not the house a family actually lives in, since that gain is already taxed at only 50 percent of the profit under current rules, before any exemption is even applied. If it passes, an owner-occupied Saskatoon sale is not affected any differently than it is today.
Where it would matter is a second property: a cottage, a rental unit, or a home you did not designate as your principal residence, since that sale could face a higher taxable share of the gain if the change goes through. Whether that happens is worth watching, but it changes nothing for the home you live in.
If you own more than one property, talk to an accountant before you list so the tax picture is settled either way, not after an offer arrives. Get your hand-reviewed valuation from Joel Dyck.
