King City is a small unincorporated community in King Township. It’s the quintessential small Ontario town with a population of just under 7,000. This small community is home to many farmers and is known for its rolling hills.

The scarcity of homes and people is perfect for those looking for a simple living. It is a great location for those looking to buy land and for those who have a laid back lifestyle. King City’s beautiful properties deserve a beautiful home, and homeowners have trusted Heritage Home.
