I don't consider trusting the city staff reports and studies to be fudging, and even if the price was equal there's no sense in building the hybrid. It only slimly beats the boulevard on transportation, and by every single other metric the boulevard is a better option.
To prefer the hybrid is to value the commute times of a minuscule fraction of commuters over all these other advantages. Are these 5-6000 suburban commuters really worth a worse pedestrian experience for the entire city? is it worth high maintenance costs? is it worth relieving traffic? is it worth removing a barrier to the waterfront? is it worth sacrificing what would be a boon to our economy? is it worth significantly reducing toronto's green house gas emissions?
That last one isn't stressed enough in my opinion.
Climate change is extremely serious and we had an opportunity to reduce our environmental footprint, while improving the economy, improving our quality of life, etc.. We said no. Canada's record on climate change has been abysmal, and we need to start factoring it into our thinking and our policy making.
