For anyone interested in the delays occuring at West Toronto, noting that this project has the possibility of delaying any expansion on the Georgetown line including westward to KW/Guelph:

My only personal comment on these projects is why they weren’t done 30 years ago when GO service was instated on the Georgetown line. The fact  all these projects are being undertaken now (Grade seperations such as West Toronto, Hagerman,  and Union Station capacity improvements), while positive,  highlights the fact we are simply behind in infrastructure investments. The short term pain will have long term gain for everyone, It’s unfortunate that we will be delaying them even further..
