Specifically, what do you think of Flyvbjerg's suggestion that it becomes a criminal offence to "knowingly manipulate the technical studies analyzing the merits of a mega-project"?
This sounds like a harsh measure, but one I agree with. It doesn't make it an offence to advocate for a project not supported by technical studies, but rather to manipulate those studies.
This would prevent a lot of the nonsense we saw with the Scarborough Subway, Sheppard Subway and these two GO Stations, where municipal and provincial politicians were either directly manipulating what was included in the technical reports, or taking measures to prevent the release of unfavourable information. This is also a measure that I believe the public would universally applaud, which would make it difficult for future governments to remove the restrictions.
Beyond this, there does need to be a fundamental restructuring of Metrolinx. This agency was supposed to usher in a new era of fact-based transit building. However, Metrolinx has just become another vehicle for politicians to interfere with transit expansion.
