According to this link that someone posted (I don't remember who), it will be sooner than that depending on the line. All day service on weekends started on the Barrie line a couple weeks ago. If the schedule is correct, all day service on the Kitchener line should start soon, and all day (or close to it) weekday service on the Barrie and Stouffville lines should be in 2017/18.
And the great question is: will that change any commuting patterns or make the trips "easier" from the point of view of a commuter/customer/user such that there is great take-up?
