Done poorly and illegally, graffiti is vandalism, but when a talented artist has the time and permission to work, there is no question of its artistic merit.

Check out the work of some of Ottawa’s top graffiti artists at the Tech Wall located at the intersection of Slater Street and Bronson Avenue.

The legal wall is an experiment by the city’s graffiti management strategy to see if it can reduce the amount of illegal graffiti an area.

Research has shown this works in the short term, but in the long term it can increase illegal graffiti due to mixed messages about its acceptance in a neighbourhood.
