Warden Creighton improved the lighting, heating and ventilation of the prison; provided better shoes, uniforms and bedding and a more varied diet to the inmates. Exercise periods were increased and extended to all prisoners. He began a lending library, night classes and improved school equipment. He introduced prison entertainment by inmates on holidays, ate his meals in the inmate Dining Hall and visited the inmates in their cells, in the workshops, on the farm and in the quarries.
Warden Creighton died on January 31, 1885 in Cedarhedge. The Daily British Whig of February 2, 1885 reported "The streets surrounding the warden's residence [were] blocked with sleighs, and nearly every prominent citizen was in attendance. The City Police force was drawn up at the door as a guard of honour the cortege was a very long one"
