Ottawa’s commercial construction market is entering a period of selective growth. While elevated office vacancies, economic uncertainty and construction-cost pressures continue to create challenges, strong demand for industrial space, retail development, institutional investment and modernized commercial properties is creating new opportunities for developers, contractors and investors.
The broader Ontario outlook is encouraging. BuildForce Canada projects construction activity to increase through 2035, supported by sustained non-residential investment and a pipeline of institutional, commercial, heavy-industrial and civil-engineering projects.
Ottawa’s Commercial Construction Market in 2026
Ottawa remains a distinctive commercial market because of its large federal-government presence, growing technology and defence sectors, expanding suburban communities and strategic location between Toronto, Montreal and the U.S. border.
Recent building-permit data highlights the strength of the market. Ottawa-Gatineau recorded $289 million in ICI building permits in June 2026, the highest monthly total among Ontario markets outside Toronto. Commercial construction was also a major contributor to Ottawa’s activity earlier in the year.
At the provincial level, Ontario’s commercial permit values increased substantially in Q2 2026, rising 60% to $3.34 billion. Although monthly permit figures can fluctuate significantly because of individual large projects, the trend points to continued investment in non-residential construction.
Industrial Construction: One of Ottawa’s Strongest Segments
Industrial construction is arguably the most compelling growth segment in Ottawa’s commercial market.
Colliers reported an industrial vacancy rate of just 2.5% in Q2 2026, while functional industrial inventory—particularly small-bay properties and sites with outdoor storage or trailer parking—remains difficult to find. Average asking net rents increased 0.7% during the quarter to $16.87 per square foot.
The limited supply of available industrial properties is creating opportunities for new construction. Demand is being supported by logistics, technology, defence, advanced manufacturing and other users requiring specialized facilities.
The scale of some current developments demonstrates investor confidence in Ottawa’s long-term industrial prospects. An industrial investment forecast for 2026 anticipates approximately 3.2 million square feet of new industrial space, with Amazon’s 3.1-million-square-foot Nepean fulfillment centre representing the dominant addition.
Defence and artificial-intelligence investment could provide an additional source of demand for large industrial and specialized facilities.
Office Construction: A More Complicated Outlook
Office construction presents a very different picture.
Ottawa’s office vacancy rate reached 15.0% in Q2 2026 according to CBRE, following another increase in available space. Large blocks of space returning to the market and federal-government space consolidation are contributing to the elevated vacancy rate.
However, high vacancy does not mean the end of office construction. Instead, it is changing what tenants and developers expect from new projects.
Colliers reported that tenants continue to favour Class A properties with modern, turnkey interiors. More than 400,000 square feet of leasing activity was completed during Q2, while average asking rents increased slightly to $17.17 per square foot.
This suggests that future office investment is likely to focus on:
- High-quality Class A buildings
- Flexible and turnkey office space
- Energy-efficient and sustainable buildings
- Smaller, highly amenitized office environments
- Renovations and adaptive reuse
- Properties serving technology, defence and professional-service tenants
Office-to-residential conversions may also continue to reshape the market, particularly where older office buildings cannot compete effectively with newer inventory.
Retail Construction Remains Resilient
Retail is another area where Ottawa is showing relatively strong fundamentals.
CBRE reports that grocery-anchored and service-oriented retail properties remain attractive to investors, while new retail plazas are achieving strong rents because of tenant demand. Food-and-beverage and service businesses are actively looking for expansion opportunities in growing Ottawa communities.
This creates opportunities for commercial construction in areas experiencing population and residential growth. New neighbourhood retail centres, medical-commercial developments, restaurants, grocery stores and service-oriented plazas are likely to remain important components of Ottawa’s construction pipeline.
Retail development is also benefiting from the limited availability of high-quality urban retail space. Prime urban and high-street locations continue to perform well.
Institutional and Public-Sector Investment
Although institutional construction is technically distinct from private commercial development, it has an important influence on Ottawa’s overall construction ecosystem.
Ontario’s ICI construction market experienced a major increase in Q2 2026, with total permit values reaching $11.24 billion. Institutional projects accounted for more than half of the provincial total.
For Ottawa contractors and subcontractors, public-sector projects can generate opportunities across a broad range of trades, including mechanical, electrical, civil, concrete, structural and building-envelope work.
The long-term Ontario forecast also points to sustained non-residential investment through 2035, suggesting that institutional and infrastructure spending should remain an important source of construction activity.
Key Growth Drivers
Several factors should shape Ottawa’s commercial construction market over the next five to ten years.
1. Defence and Technology Investment
Ottawa’s technology ecosystem and growing defence activity could increase demand for specialized offices, research facilities, laboratories, manufacturing space and secure industrial properties.
2. Industrial Supply Constraints
The shortage of functional industrial space is a major opportunity for developers. With vacancy around 2.5% in Q2 2026 and limited small-bay inventory, new construction can address a significant unmet demand.
3. Population and Suburban Growth
New residential communities create demand for supporting commercial infrastructure, including grocery stores, restaurants, medical offices, professional services and neighbourhood retail.
4. Return-to-Office Policies
Federal and other public-sector return-to-office policies could gradually increase demand for centrally located, high-quality office space. The impact is likely to be uneven, however, because government space consolidation is simultaneously releasing existing inventory.
5. Adaptive Reuse
Elevated office vacancy creates opportunities to reposition older properties. Conversions to residential, mixed-use or specialized commercial uses can provide an alternative to traditional ground-up development.
Challenges Facing Commercial Construction
The outlook is positive, but developers and contractors should not underestimate the risks.
Construction companies continue to face labour shortages, material costs, financing constraints and procurement complexity. The Canadian Construction Association reported in July 2026 that Canada’s construction-sector GDP contracted 1.3% in Q1 2026 and identified economic uncertainty, trade volatility and increasing compliance costs as ongoing challenges.
For Ottawa projects, these pressures can translate into:
- Longer project timelines
- Higher financing costs
- Material-price volatility
- Labour availability issues
- More conservative development underwriting
- Greater emphasis on pre-leasing
- Increased demand for accurate estimating and project management
As a result, successful commercial projects will increasingly depend on strong feasibility analysis, cost control and early tenant or end-user commitments.
Growth Projections for Ottawa Commercial Construction
Rather than expecting uniform growth across every commercial property type, Ottawa is likely to experience segmented growth.
Industrial construction appears positioned for the strongest near-term fundamentals because demand is exceeding the supply of suitable space. Retail should remain relatively stable, particularly in grocery-anchored, service-oriented and growing suburban locations.
Office construction is likely to recover more gradually. New development will need to differentiate itself through quality, location, flexibility and amenities rather than simply adding conventional office inventory.
Over the longer term, the broader Ontario construction outlook supports a sustained expansion of non-residential construction through 2035.
What This Means for Developers and Contractors
For developers, Ottawa’s market increasingly rewards specialization. Projects supported by strong tenant demand, pre-leasing commitments or structural supply shortages are better positioned than speculative developments without a clearly defined end user.
For commercial contractors, the opportunity lies in positioning for sectors with durable demand: industrial facilities, retail centres, institutional buildings, healthcare-related projects, technology facilities and renovations or adaptive-reuse projects.
The construction companies best positioned for growth will likely be those that combine competitive pricing with dependable scheduling, experienced project management, skilled trades and the ability to manage increasingly complex regulatory and procurement requirements.
Conclusion
Ottawa’s commercial construction market is not experiencing a uniform boom—but it is undergoing an important transformation.
Industrial development is benefiting from tight supply and strong tenant demand. Retail remains resilient, particularly in service-oriented and grocery-anchored locations. Office construction faces significant challenges but may gradually improve as return-to-office policies, adaptive reuse and demand for high-quality Class A space reshape the sector.
With Ontario’s non-residential construction pipeline expected to remain elevated through 2035, Ottawa is positioned for continued commercial construction investment.
For developers, investors and construction companies, the key will be identifying where demand is structurally strong rather than assuming every segment of the market will grow at the same rate. In Ottawa, that increasingly means industrial, specialized commercial, institutional and high-quality redevelopment projects.
