While the budget still has yet to pass, and the funding parameters/criteria remain abstract at best, Lorinc's third point is critical, particularly in light of government's sub-optimal track record on accountability.
The specifics of the Big Move funding mechanism will hopefully be articulated in the upcoming budget bill (to be introduced in early July) as they were not outlined in the May Budget. In fact,
Bill 194 does not seem to contain any references to transit, and only mentions infrastructure with regard to the so-called "Trillium Trust Act", a pool of public money that would be used "to fund, directly or indirectly, costs incurred in connection with constructing or acquiring infrastructure or other tangible capital assets." This is the reserve that would fund the Big Move inside the GTHA and other infrastructure needs outside of it.
Even without having a fix on the specifics, however, it doesn't seem likely that Hamilton would pay in without getting something back. The ongoing "either Hamilton will pay $X million and get LRT or Hamilton will pay $X million and get nothing in return" formulation has always seemed a bit dubious to me.
There are a number of active transportation/Big Move outlets for which Hamilton might be funding-eligible, and a number of variables that will impact Hamilton's prospects for LRT, not least among them the heightened competition now that the province is looking to carve up $15 million rather than $34 million.
And of course council's determination to pay (next to) nothing for a system upgrade.
