Luminato, one of Toronto&apos;s largest arts and culture events, has officially been canceled for 2020. The international festival, which launched in 2007, was developed to help revitalize the city&rsquo;s art scene after the SARS outbreak of 2003. Last year&rsquo;s event had a &ldquo;House of Mirrors&rdquo; (pictured) that invited people to walk through a disorienting, kaleidoscope-like atmosphere that presented reflections from numerous angles.
