I was embarrassed by the post and thought it was shockingly undiplomatic, especially as it was written by someone who's making decisions for the entire region. But in addition, it's wrong. This is not about being unkind to Cambridge; it's about materially disadvantaging them.
First - The LRT is not going to be much faster than the iXpress in travelling from Conestoga Mall to Fairview Mall. But for people going on to Cambridge, the LRT requires that people get off the train and wait for a bus - which means that for people going from Cambridge to anywhere in K-W, the trip will be slower and less convenient than iXpress. They are expected to contribute over a hundred million dollars - possibly several hundred million with expected cost overruns - for a transit system that is worse than what they have now.
Second - Imagine five years from now, when a company or individual is considering relocating to Waterloo Region. What signal do they get from the region's second-largest city not being on the main transit route? This isn't just about disadvantaging transit riders: it's about disadvantaging Cambridge real estate and property values and businesses. An LRT that doesn't go to Cambridge is far worse for Cambridge than no LRT at all.
In my research I have been talking to Cambridge residents, politicians and city staff, and what I hear is that they are well aware that they both have been screwed and dodged a bullet. Screwed in the ways I mention above, but dodged a bullet in other important ways. LRT would have messed up Water Street and the lovely, growing core of Galt. In addition, it looks like the municipalities are going to have to foot the bill for a lot of LRT capital costs: for replacing pavement, sidewalks and curbs that are torn up; for moving hydro polls and street lights; and so on. This was wholly unknown until Nancy Button was asked a question about it at the last Regional Council meeting. This could be tens of millions for each of Waterloo and Kitchener: I heard that Cambridge recently had to pay $2M for such capital costs when the Region built a roundabout.
Note: I like Jane Mitchell's blog a lot. I read it regularly, and I think she does us a service by being so candid in her writing. I wish I'd written a positive post about it before writing this negative one.
