Canal Park is largely a conversion of an old warehouse district into restaurants, shops (especially those dealing in antiques and other novelties), cafés, and hotels. This conversion began in the 1980s as an attempt to use Duluth's rich industrial past, the decline of which had left the city in economic turmoil at the time, as an asset in a prospective tourist industry. The Duluth Entertainment Convention Center (DECC) now connected to the new Amsoil Arena and the area's prominent entertainment venue, is also located in the district. The DECC provides an indoor connection to the skywalk system in Downtown Duluth. Many annual events such as the Bayfront Blues Festival, held in Bayfront Festival Park; and Grandma's Marathon that runs from Two Harbors, Minnesota to downtown Duluth, are held fueled by Canal Park.
