The Collingwood Municipal Building was first known as The Market Building. Construction began in the summer of 1889. The building was designed to house Collingwood's Town Hall, a Farmers' Market, retail stores, clerk's office, courtroom, council chambers and an opera house. Over the years the Collingwood Municipal Building has seen many changes. What is now the Eddie Bush Arena replaced the opera house. In 1984, the building received a massive facelift inside and out. The downtown Municipal Building dominates the streetscape with massive stone arches and clock tower.
