Exhibition Place consists of almost 200 acres parallel to the waterfront (although it is difficult to see the lake most of the time). The grounds contain a mix of heritage and contemporary buildings. They all come alive during the Canadian National Exhibition from mid-August to Canadian Labour Day (first Monday in September). The rest of the year, many of them are used for sports, plays, concerts, special events and trade shows. The largest venue for the latter is Enercare Centre. This exhibition complex built in 1997 has about one million square feet of space. Adjacent is the Coca-Cola Coliseum. This is home ice for two Toronto-based hockey clubs (one professional, one farm club). The arena also hosts other sporting events and concerts.
