Graffiti Alley is more than a series of murals, mesmerizing as they are: it represents a watershed moment in Toronto's relationship with legalized street art. When it was legitimized in 2011 through the efforts of the Queen Street West BIA, it also gave birth to StART — the city-sanctioned program in charge of nurturing legal street art — and paved the way for equally brilliant revitalization projects like the beautiful art of Underpass Park. The 1 km alleyway has become a staple feature of the city. It's been the locale for mini street fests, music videos and more.
