They say the initial investigation could not find evidence of gunfire at the scene.
There were no injuries reported as a result of the incident.
On Tuesday morning, police were called to a business on Haddington Street after the owner found a hole in a garage window.
Officers believe the hole in the window was caused by a bullet.
A police spokesperson says the investigation shows that the two incidents are related.
There have been three daylight shootings in Kitchener as well as an incident involving a man flashing a pistol over the past two weeks.
Police have not said whether any of the shootings are connected.
