In 1797, he was named to the Heir and Devisee Commission, which dealt with transfers of land title that occurred due to inheritance, sale or exchange of title. Warren also served as lieutenant-colonel for the 3rd Lincoln Militia. He was customs collector at Fort Erie from 1801 until his death at Fort Erie in 1813. His son John served in the Upper Canada assembly and also succeeded his father as customs collector. References
