This is a very specific question that requires more specific questions answered. You require an engineering consultant to give you the exact specifics you seek.

Generally, fire-rated assemblies are required between different occupancy types, such as between a corridor/stairwell and a residential unit, to prevent the spread of fire and smoke. These assemblies typically consist of fire-rated materials, such as gypsum board (drywall), fire-rated doors, and fire-resistant insulation.

The OBC specifies the fire rating required for such assemblies, which indicates the amount of time the assembly can withstand fire exposure. Common fire ratings include 1-hour, 2-hour, and 3-hour ratings, depending on the specific application and building type.

As for the studs used in constructing these assemblies, both wood and steel studs can be used, but they must meet the requirements outlined in the OBC for fire resistance and structural integrity. Typically, steel studs used in fire-rated assemblies are designed and manufactured to meet specific fire-resistance ratings.

To get precise information about the requirements for your specific situation, including minimum fire safety spacing and acceptable stud materials, it's recommended to consult directly with the municipal building department in Toronto or a qualified architect or engineer familiar with local building codes and regulations. They can provide guidance tailored to your project and ensure compliance with all applicable requirements.

Depending on the size of the building it may be required to be of noncombustible construction in which cases wood studs are not permitted at all. Size and spacing of studs is typically determined by what the wall is supporting above. The spacing may be up to 24" depending.
