"We need answers now," said Ariela's father Victor Navarro before heading in to the funeral at St. Jude's Roman Catholic Church on Weston Road.
Ariela's sister Aluen said her family is struggling to come to terms with the loss of a girl she described as a "free spirit" who "lived life to the fullest."
"She was a beautiful girl that would do anything for her family and friends. She was able to connect with anyone she met."
Family friend Wichita Espina was distraught as she headed in to the church.
"They are a lovely family, it's not fair that this happened to them," she said.
Navarro-Fenoy died after she was shot near Dufferin Gates as the crowd was leaving the club following an after-party for Drake's OVO Fest.
Duvel Hibbert, 23, was also killed in a shooting inside the club that happened moments before Navarro-Fenoy was shot outside.
Police say they're looking for two men who they considered to be persons of interest in the case but so far there have been no arrests.
