Home » The Great Condo Insurance Rollercoaster: A Stakeholder’s Guide to the Ontario Market


If you own or live in a condominium in the Greater Toronto Area (GTA) or across Ontario, you have likely noticed a recurring theme during your Annual General Meeting (AGM): Condo insurance is getting more expensive, and the deductibles are getting higher.
Understanding the “Insurance Rollercoaster” is essential for every unit owner, investor, and stakeholder. It explains not just monthly maintenance fees, but also the personal financial exposure of every homeowner.

Ten years ago, the Ontario condo insurance market was remarkably stable. Rates were low, competition was fierce, and premiums increased by a predictable 3% to 4% annually. Because insurance was affordable, many stakeholders stopped paying close attention to it.
However, this stability was a “quiet before the storm.” Rates stayed low for so long that insurance companies eventually reached a point where they were paying out far more in claims than they were collecting in premiums.
Around 2018, the market corrected violently, entering what is known as a “Hard Market.” Some corporations saw their premiums jump 30% to 50% in a single year. Insurers either raised rates aggressively or exited the residential realty market entirely. We are only now emerging from that period as insurers become profitable again and new competition enters the market.
In Ontario, water damage is the single biggest driver of insurance costs. It isn’t fire or theft that typically drives rates—it’s a burst pipe on a high floor.
Water damage in a high-rise tower is a vertical catastrophe. A single leak can impact dozens of units below it. Furthermore, modern building codes have made cleaning up a leak significantly more expensive. It is no longer enough to just mop the floor; specialized drying equipment, moisture sensors, and mold prevention protocols are now mandatory.
To stay profitable, insurance companies have raised water deductibles. A decade ago, a $5,000 water deductible was common. Today, $25,000 is the new normal, and $50,000 or $100,000 is not unusual for buildings with a history of leaks. This shifts the cost of “minor” floods away from the insurance company and directly onto the condo corporation and, potentially, the unit owners.
Many buyers believe that moving into a brand-new condo means they are safe from insurance issues. In reality, new buildings are often viewed as higher risk than 10-year-old buildings.
During the first 24 to 36 months, construction defects often reveal themselves. Pipes may settle and crack, gaskets might fail, and HVAC systems might be improperly calibrated. Insurers call this “infant mortality” of building systems. Because of this frequency of early-life leaks, some insurers are hesitant to cover new towers, or they do so only with extremely high water damage deductibles.
Even if the insurance market is “soft” and rates aren’t rising, a premium might still go up. The reason is the Building Limit.
By law, a Condo Corporation must insure the building for its full Replacement Value. In the last 10 years, the cost of construction in the GTA has skyrocketed. Labor shortages and material inflation mean it costs significantly more to rebuild a tower today than it did in 2014. If a professional building appraisal finds that the cost to rebuild has doubled, the premium must increase to cover that new, higher limit of insurance.
As a unit owner, your personal unit insurance (HO6 policy) is inextricably linked to the building’s master policy.
If a leak originates in a unit and causes $40,000 in damage, and the building has a $50,000 deductible, that amount will likely be charged back to the owner. If a personal insurance policy doesn’t have enough “Deductible Assessment Coverage,” the owner could be personally responsible for that $40,000. This is why understanding the building’s deductible is just as important as knowing the monthly fees.
