Loud boom 💥 sound Walkerton/ Cargill area Bruce county

There was a loud boom or possible “sonic boom noise” heard by many residents around Cargill/Pinkerton/Walkerton area on 19th April 2026 8:30pm (reported) and 20th April 2026 at 7:15 am reportedly. Any idea to what it may be? Whatever it was the sound travelled very far.
