Owned or rented

The split is close to even, which is the point most readers miss: the Crown is a major office tenant, not only an owner.

Condition is recorded for 2,153 structures. Among those, 506 of 1,902 are rated Poor or Critical by their own custodian. That is a federal stewardship rating and says nothing about any commercial building class.

Questions

What this record is and is not.

What is in this record?

Every structure in the Treasury Board Directory of Federal Real Property that carries an Office use type: 3,229 buildings across 51 metropolitan areas and beyond, held by 45 federal departments, agencies and Crown corporations.

Is this the Canadian office market?

No, and the distinction matters. This is the federal government’s own property holding. It excludes every privately owned office building, so it describes one large occupier rather than a market. 1,537 of these structures are held on a lease or licence, meaning the Crown is a tenant in a building someone else owns.

What does the condition rating mean?

It is the custodian’s own assessment on a federal scale, recorded for 2,153 of the 3,229 structures and absent for the rest. Of those with a rating, 506 are recorded as Poor or Critical. It is a stewardship measure for federal reporting, not a market building class, and it is not comparable to any commercial grading.

Is the floor area office space?

Not always. Floor area is the whole structure, and 878 of these buildings carry another use as well as office. 2,351 record office as their only use. Totals on these pages are of building floor area, not of office floor area.

Does this include rents or availability?

No. The Directory publishes holdings, not transactions. No Canadian public source publishes office rents, vacancy or availability, so nothing of that kind appears anywhere on this site.

Boundary: This is the federal government’s own property holding, not the Canadian office market. It excludes every privately owned office building, and the Directory records condition on a federal assessment scale rather than a market classification. It is not a rent, vacancy or availability source.
