Yes, a war is slightly higher on the federal government's priority list than making sure Oliva doesn't have to raise taxes.
Toronto must, and Toronto will raise taxes.
That's not really in question anymore.
However, Ottawa is allowing people into the country as refugees and then expecting Toronto to pick up the tab.
The Feds usually pay something, eventually, but less than what is required and several months late.
Seems to me, if they are causing the problem, they ought to pay, in full, in real-time. That's not an unfair ask.

Likewise, Its Ottawa that is pushing high levels of population growth in general, the burden of which (transit, parks, sewers, watermains, roads, libraries etc.) falls on lower orders of gov't.
(hospitals, schools etc. as well, but there the burden is provincial)
Once again, I would say, if Ottawa wants Toronto to handle another 1,000,000 residents within the City, and serve as the hub for an extra 2,000,000 or more, then Ottawa should be opening up its wallet to pay for the requisite infrastructure.
It should also be doing that in advance of the need, rather than years later.
