On October 24, 1932, he came to Kingston Penitentiary as Warden with the task of regaining the control and discipline of the institution. This had been lost due to the 1932 riot. He held the position of Warden until June, 1934.

It was during his tenure that Cedarhedge stopped serving as the official Warden’s residence. Instead, it became the Administration Offices of K.P. On November 17th, Warden Megloughlin reported that his offices were now moved from the penitentiary into Cedarhedge, or “building A-1” (See Nat’l Archives – RG73; Vol.22; File 6-A-1; Vol.1). The penitentiary administration was now able to convert former office space within the Kingston Penitentiary compound into more cell accommodations in order to relieve overcrowding.
