According to the KW-Record (and GO sources) The EA has been approved by the GO Environment Minister.

However, Jeff Outhit, who seems to forget that a rush-hour highway commute to Union Station is easily nearly 2 hours long and only getting worse… correctly states that funding has yet to be allocated, and the project will not proceed until this is done.

Jeff: The quickest driving commute to Union is 1 hour 13 minutes no traffic, obeying speed limits. Everyone knows traffic bunches at Milton and lasts until Pearson,  and adds about 20 minutes, sometimes more, especially in pockets around Toronto (Gardiner Expressway, anyone?). This will only continue to get worse. The 1 hour and 33 minute driving commute is now nearly equal to the proposed 1 hour 45 minute GO transit commuter time. GO will only improve from here, as more grade seperations, track and signalling improvements are put into place. I suspect a GO commute could be shaved to 1 hour 15 minutes. Imagine that..

While residents of Guelph, Kitchener-Waterloo and Acton await the decision (yes or no) regarding the westward GO Train expansion from Georgetown, GO is already calling for tenders regarding a temporary layover facility. The following was found on the GO Tender call section of their website.

…. meanwhile the politicians have yet to make an official announcement. Thoughts? Thanks to Tom A/David G for the buzz.
