As an old form of art in a new country, opera came to Canada relatively late. Although the first composition can be traced back to the seventeenth century it was not until 150 years later that Canadian opera caught up. Canadian opera became especially fashionable on Canada's 1967 centennial year. These celebrations set off an interest in operas among Canadian composers that was never seen before. This interest in opera, among composers and audience alike, is noticeable until today. However, most Canadian operatic works are not known internationally since many of them specifically concern Canadian themes and are small in scale.
