Graffiti is a form of vandalism that damages property, causes public safety issues and can result in liability. It negatively impacts local neighbourhoods by making public spaces appear unsafe. More often than not, graffiti is also used as a means to mark territories.

The law categorizes graffiti as a criminal act when it involves defacing property with damages under $250. It's a nuanced form of vandalism, with the first offense treated as an infraction and subsequent offenses as misdemeanors.

Graffiti can damage public or private property, spread hate speech, create a safety hazard, and contribute to a negative community image.

Smith, a visual arts teacher at the iSchool, said that “If there is consent, it's art. If there is no consent, then it's vandalism but still art.” Graffiti is art regardless of whether it's on someone else's property, which they may not want there.
