The Ottawa office leasing market continues to evolve in 2026 as employers, landlords and employees adjust to a workplace environment that looks very different from the one that existed before the pandemic. Hybrid work remains an important part of the equation, but increased return-to-office requirements, changing tenant expectations and a growing emphasis on quality are creating new opportunities across the National Capital Region.For businesses considering a lease renewal, relocation or expansion, the current market presents something we have not seen in Ottawa for many years: meaningful choice combined with negotiating leverage.
At the same time, the headline vacancy numbers do not tell the entire story.

Ottawa Office Vacancy Has Increased — But There Is More to the Numbers

According to Colliers' Q2 2026 Ottawa Office Market Report, Ottawa's overall office vacancy rate increased to approximately 13.2%, compared with 12.9% in the previous quarter. Net absorption during Q2 was approximately negative 205,000 square feet.

On the surface, those numbers might suggest weakening demand. However, a closer look provides a more nuanced picture.

Colliers reported that more than 328,000 square feet of previously proposed residential conversion space returned to the office inventory during the quarter. Another approximately 70,600 square feet was vacated by the federal government. Despite those additions, approximately 402,000 square feet of leasing activity was completed during Q2.

That distinction is important.

Ottawa is not experiencing a simple collapse in office demand. Instead, we are seeing a reallocation of demand. Companies are reconsidering how much office space they require, where that space should be located and, increasingly, what quality of environment they need to provide employees.

The Flight to Quality Continues

One of the most significant trends I see in the market is the continued flight to quality.
Companies may occupy less space than they did five or ten years ago, but many are willing to invest more in the space they retain.

Modern Class A buildings, efficient floorplates, natural light, upgraded common areas, good parking, access to public transit and nearby amenities are increasingly important considerations. Move-in-ready space is particularly attractive because tenants can reduce construction costs, shorten their occupancy timeline and avoid some of the uncertainty associated with major leasehold improvement projects.
Colliers reports that this preference helped average Ottawa net asking rents increase slightly to approximately $17.17 per square foot in Q2 2026.

The result is effectively a two-tier market.
Well-located, professionally managed and recently improved buildings can perform significantly better than the overall vacancy rate might suggest. Older buildings requiring substantial capital improvements may face longer marketing periods and greater pressure to provide competitive tenant inducements.

For landlords, simply having available office space is no longer enough. The space has to compete.

Return-to-Office Is Becoming an Important Ottawa Factor

Ottawa is unique among Canadian office markets because of the enormous influence of the federal government.

That makes the federal government's 2026 return-to-office policy particularly significant.
As of July 6, 2026, federal public servants eligible for hybrid work are generally required to work onsite four days per week, while executives have been required onsite five days per week since May 4. The government has acknowledged that while many departments have sufficient space, others may require additional capacity.
For Ottawa's office market, this creates an interesting dynamic.

For several years, government office consolidation and efforts to reduce the federal real estate footprint created uncertainty. Increased workplace attendance could place some of those assumptions under review and potentially generate new requirements for government-occupied or government-compatible office space.

The impact will not happen overnight, but it is an important trend for landlords and tenants to watch through the remainder of 2026 and into 2027.

Downtown Ottawa Remains a Market of Opportunity

Downtown Ottawa continues to face challenges, but it should not automatically be dismissed by private-sector tenants.
In fact, the availability of downtown office space can create excellent opportunities for organizations willing to consider the core.
Companies may find professionally managed buildings, established infrastructure and high-quality existing improvements at economics that would have been difficult to achieve several years ago.
The key is evaluating the total occupancy cost, rather than simply comparing asking net rents.

Additional rent, operating costs, parking, utilities, tenant improvement allowances, free-rent periods, construction costs and restoration obligations can materially change the economics of competing properties.

A building quoting a lower net rent is not necessarily the least expensive option.

Suburban Office Space Remains Competitive

Ottawa's suburban office markets also remain important, particularly for companies whose employees live outside the downtown core.

Kanata continues to attract technology and defence-related businesses, while areas including Nepean, Ottawa South and the east end can provide convenient highway access, parking and proximity to employees.
CBRE's 2026 Canadian outlook highlights a broader trend toward buildings that can help employers "earn the commute." As organizations ask employees to spend more time in the workplace, accessibility, amenities and the quality of the employee experience become increasingly important.
That concept is particularly relevant in Ottawa.

For some companies, a suburban location with free or lower-cost parking may be more effective than downtown space. For others, access to LRT, restaurants, government clients and downtown amenities may outweigh parking considerations.
There is no longer one correct office strategy.

Tenants Have Leverage — But Good Space Is Still Competitive

dictate every aspect of a transaction.
That is not necessarily the case.
Tenants generally have more negotiating leverage than they did when vacancy was extremely low, and landlords may be prepared to negotiate tenant improvement allowances, fixturing periods, free rent, expansion rights, renewal options and other lease provisions.

However, the best spaces still attract interest.

A modern, well-improved suite in the right location can lease relatively quickly, particularly when compared with older space requiring substantial construction.
This is why tenants should begin evaluating their options well before their existing lease expires. Depending on the size and complexity of the requirement, starting the process 12 to 18 months before lease expiry can provide considerably more negotiating leverage.

What Should Ottawa Businesses Do Now?

For tenants, the current market represents an opportunity to rethink the workplace rather than simply renew the existing lease.
Ask whether you still need the same amount of space. Consider how frequently employees are actually coming into the office, whether the current configuration supports collaboration, whether parking or transit is more important to your workforce and whether your existing building still represents good value.

Then compare staying versus relocating on a complete financial basis.
For landlords, the message is equally clear: quality matters. Buildings and suites that are move-in ready, well maintained and positioned around the needs of today's workforce will increasingly outperform undifferentiated inventory.

Looking Ahead

Vacancy remains elevated compared with historical norms, but leasing activity continues. Companies are becoming more deliberate about their workplace strategies, employees are spending more time in the office, and the federal government's evolving accommodation requirements could become an important source of future demand.

For businesses, that creates opportunity.
The organizations that benefit most will be those that start early, understand the alternatives and negotiate their leases based on both current market conditions and their longer-term business strategy.
