National office vacancy rates fall most since 2020

Key Concepts

• Office Vacancy Rate: The percentage of all available office space that is unoccupied.
• Return-to-Office (RTO) Mandates: Corporate policies requiring employees to work from the office rather than remotely.
• Supply-Demand Cycle: The cyclical nature of real estate where periods of oversupply (too many buildings) eventually lead to undersupply due to halted construction.
• Adaptive Reuse: The process of converting existing office buildings into other uses, such as residential housing.
• Top-Tier Space: High-quality, modern office environments that are currently seeing the highest demand.

1. Market Overview and Trends

A new report from Colliers Canada indicates that the national office vacancy rate has decreased by a full percentage point compared to the previous year. This represents one of the most significant improvements in the sector since the onset of the pandemic. The market is currently transitioning from a five-year period of oversupply and low demand to a more balanced state, driven by a lack of new construction and a resurgence in demand.

2. Primary Drivers of Market Tightening

• Return-to-Office Mandates: Major tenants, including government agencies, banks, insurance firms, and tech companies, are increasingly requiring staff to return to the office. This is particularly pronounced in downtown Toronto.
• Halted Construction: Due to the prolonged period of low demand, new office construction was put on hold. Adam Jacobs, Head of Research at Colliers Canada, notes that construction has slowed to "almost zero" in most major cities and is unlikely to pick up for the remainder of the decade.
• Workforce Expansion: Despite the prevalence of hybrid work, the total number of employees at major firms has grown significantly over the last six years due to Canada’s population growth. Companies now require more space to accommodate larger headcounts than they did pre-pandemic.

3. Regional Variations

• Toronto: The financial core is experiencing a rapid turnaround with strong leasing activity, outperforming the suburbs.
• Calgary: A unique case where the city has implemented a government-backed initiative to convert long-term vacant office towers into residential units, effectively shrinking the total office inventory.
• Ottawa: Remains an outlier, as its market performance is heavily tied to the operational decisions of the federal government.
• Small Markets: These are described as less predictable and more susceptible to volatility based on single large-scale relocations or new building projects.

4. The Reality of Office-to-Residential Conversions

While there is significant public interest in converting vacant office space into housing, Jacobs argues that this is rarely financially viable in major markets like Toronto and Vancouver. The high cost of purchasing office assets combined with the complex engineering required to retrofit them for residential use makes this a "simple solution" that is difficult to execute in practice.

5. Future Outlook: The Risk of Shortage

Jacobs suggests that the market is highly cyclical. Given that there is almost no new construction planned for the rest of the decade, combined with continued economic and population growth, there is a distinct possibility that the market will shift from a surplus to a shortage of office space within five years.

6. Notable Quotes

• "We spent 5 years with sort of too much supply and not enough demand and then we woke up in 2026 and found we had too much demand and suddenly there isn't anything being built." — Adam Jacobs
• "It seems like a simple solution but the practicalities of it are quite different so aside from a few cases on the margins I don't think you'll be seeing conversions of office." — Adam Jacobs (regarding office-to-residential conversions).

Synthesis

The Canadian office market is currently undergoing a structural correction. The combination of a "swelling" workforce, the cessation of new construction, and the successful implementation of return-to-office mandates has effectively tightened the market. While cities like Calgary are experimenting with adaptive reuse, the broader trend is a return to historical norms where downtown cores remain the primary hubs for major corporate tenants. The long-term concern for the industry is no longer vacancy, but rather a potential future shortage of space as the economy continues to expand without new supply.
