Kipling station does not have seperate bus bays. The buses stop on the north side of an island station. The south side is a ghost platform for an ICTS type rapid transit system potentially to the airport.
Islington is the station with seperate bus bays similar to the old Victoria Park station. This station is also slated for modernization which includes building a new island station north of the present bays. The old station will then be demolished.
As for an extension to Sherway gardens, it might be a reality in 30-40 years.
Maybe after finishing the Spadina extension, Transit City, Yonge extension and Dowtown Relief Line.
