Our current zone paradigm is created off a lot of flawed assumptions made in the 1950's, with zero attempt to ever shift the paradigm. This schema is based off what works or does not about other countries, most notably Japan. Tokyo went from the most expensive place to live in the world, to a place that charges LESS rent every year, because better housing is going up all of the time. The solution was streamlining and simplifying zoning laws, to the point that if you are in-zone and to-code, no one can question what you are building.
Building codes are created at a federal level, while cities and provinces pick which zones apply in their territory. Things like noise and pollution bylaws will also be on a local basis. This includes other things that are restricted, like casino licences.
I will be making the assumption of maximum 12ft per floor. Undercroft and peaked roof are not included. If you do not have a peaked roof, you lose 12ft off the maximum. Because you are too stupid to understand that peaked roofs are useful.
Also, structural requires for the height will obviously included.
5% of the land space is LowRes, while the rest is reserved for agricultural production / support. Every agricultural building can have 24ft of unlimited residential space on top.
Parking for civilian vehicles, (my province calls them class 5), is considered part of the LowRes part, not the agricultural part.
Parking for larger vehicles, (class 1-2-3), is considered part of the agricultural part.
5% of the land space is MedRes, while the rest is reserved for agricultural production / support. Every agricultural building can have 48ft of unlimited residential space on top.

Either 1/3 of the floor space, or the entire lower floor, can be commercial. The rest is residential, with no maximum number of units.
Comes in (4)-(6), designating the maximum number of floors.
MedRes(4) - Maximum Height: 60ft
MedRes(5) - Maximum Height: 72ft
MedRes(6) - Maximum Height: 84ft
Either 1/3 of the floor space, or the entire lower two floors, can be commercial. The rest is residential, with no maximum number of units.
The added number indicates the maximum number of habitable floors.
Minimum - HighRes(6): Maximum Height: 84ft
Maximum - HighRes(20): Maximum Height: 264ft
Either 1/3 of the floor space, or the entire lower four floors, can be commercial. The rest is residential, with no maximum number of units.
Cities can designate any above-ground two-floor height as needed for transport, as is required by the city's transportation system, along with 2 subterranean levels.
Either 1/3 of the floor space, or the entire lower eight floors, can be commercial. The rest is residential, with no maximum number of units.
Cities can designate any above-ground two-floor height per 15 floors as needed for transport, as is required by the city's transportation system, and must provide express elevators between these, and any access floors, along with 2 subterranean levels.
No maximum number of commercial floors.

But, you might, ask, if they can add as many people as they want, what are they going to do with the cars?
Tokyo has a solution to that, too. No roadside parking, (deliveries excepted). Every lot has to figure this out on their own.
But every lot can also add a complete floor of parking, with denser zones being able to have their own parkades.
If you place one medium density zone within a 10/15min walk of the low density zones, then public transport is incredibly easy to plan and implement: you just go from medium to medium.
That, and bike paths, (NOT BIKE LANES), but that a different post.
