The hit of the town in the hub of downtown action at the city bandstand is where you'll find everyone on Wednesday evenings. That's when the City of Ontario's Concerts in the Park are rocking, and people are dancing. Bring some bites to eat, lawn chairs and settle into a free concert held most Wednesdays. Ontario's Summer Concert Series is back! Kicking off at Ontario Town Square on Wednesdays and wrapping up Thursdays at Celebration Park North, this beloved seasonal tradition brings a mixture of returning fan favorites and acts brand new to Ontario. Enjoy pre-entertainment, food, games, and prizes before the show and experience the sounds of summer under the stars.
