I can assure you that federal agencies don't make any decisions on their Toronto land holdings based on what's good for the city of Toronto.
And that lovely razor-wired, so-called naval base can't accommodate a single naval ship. The handful of "trainees" can go train elsewhere (perhaps at a real naval base with real naval ships).
What we should be doing is asking that Queens Park demand the feds (and especially the TPA) to piss off and give their land holdings to the City. They have been nothing but detrimental to Toronto.
What does this have to do with fire and police...those things are actually useful.
Just because you are clueless about what happens at these places does not make them useless. To start with HMCS York, aside from being a naval reserve training facility, routinely assist the TPS, CBSA and CCG on maritime ops and security, search and rescue, maritime safety and navigation. Not every naval station has to have giant warship parked out front to be useful.
The reservists who work there are also trained in diving to remove underwater hazards and to deal with found explosives (or something planted with a more sinister intent). And they are routinely called on by various authorities in the area for support. Neighbouring Fort York and Moss Park down the road have a comms regiment setup to provide communications in the event of a major disaster. They also house a reserve medical unit that can set up ambulatory care (smaller than a field hospital) in emergencies.
Various governments have considered moving these facilties out over the years. And they all reach the same conclusions. Recruiting would suffer when reservists have no place local to train, to the detriment of our national capabilities. And moving these facilities away from urban areas dramatically hampers response for mobilizing other forces during any incident or emergency. Nothing like having a familiar operating environment, with personnel having local knowledge. Each of those armouries is set up with secure communications to various headquarters, stores of medical supplies, spare parts and ammunition that allow it to support other units that need to operate in the vicinity. If the land is that valuable, you could always up the regular force budget by a substantial amount and build bases outside Toronto staffed with full-time personnel (hard to get that many reservists elsewhere)....somehow I don't think you'd like that kind of expenditure.
The objection is also bizarre. Ever been to New York City? You'd be stunned at the land holdings by their armed forces in NYC (good chunk due to history). Much of it very prime property, including a recruiting station at Times Square, and a fully functioning naval base on the waterfront (not just a tiny building like HMCS York). You won't find too many New Yorkers complaining. And to complain about 3 tiny facilities in the downtown core of Toronto? Most would find that laughable.
BTW, the land held by defence installations does not fall under the TPA and would not be handed over. Good luck getting DND to declare these lands surplus.
