What sets Nicoll Investigations apart from other Ontario private investigators? Our attention to detail and our commitment to obtaining positive professional results on each case we accept.


The missing person search seeks to locate parties who may or may not want to be found. The missing person search is used to find long lost friends, lovers, and relatives. Locate searches are also used in cases of adoption, as you may need to find your birth parents to learn of your medical history, or you may be a biological parent (birth mother, birth father) looking for children given up at birth for adoption.


Specializing in cold case investigations.  In Toronto alone there are more than 500 Cold Cases on file.  We can investigate and review cold case files, often turning up new leads and assist in finding witnesses using advanced techniques like Spatial Statistics and Geo Profiling.


Many times lawyers need to find the next of kin or heirs to an estate. In some cases the identity of these parties are known but last known addresses are years old. In other cases there are only vague references to survivors who may be getting on in years or may even be deceased.  If you need to find heirs to an estate, whether it involves the execution of a will or state probate, a private investigator is the key to tracking these people down.
