HALIFAX -- Residents of North Preston, a community outside Dartmouth, Nova Scotia, are upset after a shocking description of their community appeared on a popular urban mobility app. While the description has been removed, many in the community say it should have never happened. Halifax police are investigating a possible hate crime after receiving complaints about a smartphone app that used a racial slur to describe a predominantly Black community west of the city. The Israel-based owners of the public transit app Moovit -- used by 50 million transit riders in 112 countries -- issued an apology Wednesday and removed the offensive description of North Preston, saying the use of the N-word was highly inappropriate and racist.
