Friends and family attended the services at Malvern Christian Assembly amid a heavy snowstorm.
Inside, friends later told CBC News, Diljohn's grandparents shared a letter the young girl had once written, and that the service was full of music — a passion of the young girl who sang in the school choir at Woburn Collegiate Institute.
It was "very uplifting and spiritual," said friend Shailana Williams. "It was a great way to help us remember her."
Diljohn was "always smiling," said Jyae Lalic, another friend. "She just seemed like a really happy girl."
Diljohn, known to loved ones as "Momo," was struck and killed on Dec. 19 just moments after exiting the bus that hit her.
The driver failed to remain at the scene, though it is not clear if the driver realized Diljohn had been hit.
The TTC is investigating and has fast-tracked a review of its hiring and training practices in the wake of this and other recent incidents that have brought safety on the transit service into question.
The TTC had earlier offered to pay up to $20,000 to help cover funeral expenses. The family declined, and is fundraising to cover costs.
