Ontario Town Square is located on the east side of historical Euclid Avenue between B and C Streets, in downtown Ontario. The square was built as part of the revitalization of the downtown area to support various programmed events, and it’s a genuinely pleasant spot to spend an hour with your dog.

The park is organized around a diagonal pedestrian promenade with a central clock tower as its focal point. Different areas branch off at various scales as you walk through, so it doesn’t feel cramped or monotonous. Along the promenade on the north side of the tower, there’s a 34-foot history wall created by local artist Andrea Benitez. The wall features 20-inch-high seat walls on each side depicting Ontario’s history and community—it’s worth stopping to read while your dog takes a break.

The square’s outdoor amphitheater stage has a tile wall with a collage of original artwork showing graphic historical symbols representing Ontario’s past, present, and future. It’s more artistic and thoughtfully designed than typical downtown parks, with actual character rather than feeling generic. Open lawn areas spread throughout, which gives dogs room to move around comfortably, especially during quieter times of day.

The park includes a children’s tot lot if you’re visiting with both dogs and kids, a palm court area that provides some shade, and a rose garden along with conservation landscaping. The mix of hardscape, planted areas, and open lawn means there’s visual interest as you walk around—it doesn’t all blend into one monotonous stretch.

Being in the heart of downtown, the square works best for a quick morning or evening visit rather than extended play sessions. The surrounding blocks have some foot traffic, so it’s good for dogs comfortable with urban activity. The deliberate landscape design and public art installations make it feel more like an actual community gathering space than just a dog park, which is refreshing.
