About
Provided by Lenczner Slaght
In this highly developed practice area, we cover all facets of insurance litigation. Our lawyers draw on extensive trial and appellate experience to advise clients on the spectrum of policy, coverage and defence matters.
With over three decades of experience, Lenczner Slaght has a proven record in litigating coverage cases among and against insurers involving issues including trigger of coverage, allocation of defence and indemnity, covered/excluded claims, obligations among primary and excess insurers, reinsurance, drop-down matters and run-off coverage.
We have provided counsel in reinsurance disputes in many forums and are frequently engaged in cases where insurance carriers face questions around policy interpretation, bad faith, punitive damages, and other areas of insurance, including alienated premises exclusion, cleanup costs as damages, expected or intended damage or injury, known loss, late notice, "other insurance" issues, owned property exclusions, post-acquisition coverage and pollution exclusion (sudden and accidental, as well as absolute).
Drawing on our litigation experience, we are also retained to defend significant matters including class action defence, disputed directors’ and officers’ liability, environmental and property damage claims, large product liability claims, professional negligence, and all manner of commercial liabilities.
No matter how challenging the dispute, we’re ready to help.
