Go Transit Delays and cancellations not being sent out on go alerts

This morning on the Lakeshore Line in burlington the train that normally arrives at 7:15 was 17 minutes late. The 7:25 arrived on time but they decided it would bypass some stops so when the 7:15 train arrived the station worker announced that the 7:43 train was behind us. Our conductor had to correct her so people were not left stranded.

When I got to work I noticed none of these were mentioned in Go Transit Alerts is it possible that they are not being logged in the 90% on time stats either? I remember arriving late on a train and complaining at customer service where they claimed my train was not late when on the board it showed yellow for the next train east since ours was late arriving.

I would love to hear answers on this from someone from Go Transit reading this. Please comment and I will approve them. I think other riders would love to hear what Go Transit has to say.
