Is it racial profiling, or making a decision based on dress and demeanor of the person?
As a person spending lots of time in downtown Toronto it didn't take me long to be able to pick out the gang members from the general population.  
Dress, attitude and language says it all and I am not talking just about black gang members, I am talking about all gang members.   The only issue is distinguishing between real gang members and poseurs.
BTW, who actually takes anything the Ontario Human Rights Commission seriously?  They are in the business of discrimination.
