Flight to Quality Continues Across Canada’s Office Sector
CoStar Group forecasts Canada's office vacancy rate to decline to 8.7% by 2028, with higher-end assets outperforming. Vacancy peaked at 10.4% in Q2 2025, falling to 9.8% in Q2 2026. Rent growth for premium assets is expected to reach 4%, compared to 2% for others. The decline is driven by limited new construction, not increased demand. CoStar Group (NASDAQ: CSGP) is a global leader in commercial real estate data and analytics.
