I read the same piece.........
A link to the relevant legislation:
Welcome to the new e-Laws. It’s now easier than ever to find Ontario laws. We welcome your feedback.

From the above, in the section titled:
View attachment 455998
View attachment 455993
It appears the province retained for itself, in the legislation, the right to re-write the City budget rules under the Act.
Though, regulations generally have a time lag in taking effect.

I can't find any reference in the Act to 'Acting Mayor' or 'Acting Head of Council'.
Which does make for an interesting question, a Mayor pro-tem really a Mayor?
LOL
