of the former route 77/11. Route 55A became route 55. Route 55B became route 56. Route 55C became route 57. (Later changed to 57A.) Route 66 retained its number for a couple of years, then it was absorbed by the route 57A. Route 77/11 became route 33. Couple years later the route was split and the services were incorporated into route 54 (Bayview Avenue), route 57 (Stonehaven Avenue) and route 55 (branch 55B, servicing the area north of Davis drive). Currently YRT is considering converting the 55B branch into a separate route 59 which will also incorporate route 44. Routes A1 and A2 became routes 31 and 32. Both routes were restructured with the arrival of the Viva service.
