Commercial Umbrella & Excess Liability Insurance
Commercial umbrella and excess liability insurance can provide additional liability limits above scheduled underlying commercial policies — such as commercial general liability and commercial automobile — for Windsor-Essex and Ontario businesses. It is not Personal Umbrella Insurance, which sits over personal home and auto. Umbrella and excess forms differ; underlying limits, exclusions, and follow-form behaviour vary by insurer. Additional limits are not guaranteed and are not available from every market for every risk.
For Windsor–Essex and Ontario businesses that need higher commercial liability limits over CGL, commercial auto, or other scheduled underlying policies — not individuals seeking Personal Umbrella Insurance over home and personal auto.
What's covered
How commercial umbrella and excess liability typically relate to underlying commercial policies — without implying every business qualifies or every insurer offers the same form.
Umbrella limits sit above — they do not fix an inadequate primary program: Insurers usually require minimum underlying CGL limits before an umbrella will attach. Exclusions in the primary or the umbrella can still apply. Drop-down behaviour for exhausted primaries depends on form.
