Mutual Street Arena, initially called Arena Gardens or just the Arena, was an ice hockey arena and sports and entertainment venue in Toronto, Ontario, Canada. From the time period of 1912 until 1931, with the opening of the Maple Leaf Gardens, it was the premier site of ice hockey in Toronto, being home to teams from the National Hockey Association (NHA), the National Hockey League (NHL), the Ontario Hockey Association (OHA) and the International Hockey League (IHL). It was the first home of the Toronto Maple Leafs, who played at the arena under various names for their first 13.5 seasons. The Arena Gardens was the third rink in Canada to feature a mechanically-frozen or 'artificial' ice surface, and for eleven years was the only such facility in eastern Canada. In 1923, it was the site of the first radio broadcast of an ice hockey game, the first radio broadcast of an NHL game, and the first broadcast of an ice hockey game by long-time broadcaster Foster Hewitt.
