Having read the excellent The Arnold Scheme about RAF recruits learning to fly in the US, I note that those washed out from pilot training remustered in Canada. While many went on to retrain and became single-winged aircrew of assorted flavours, a number ended up undertaking general duties, including cleaning or kitchen duties, at various RCAF stations until they were demobbed in 1945-46. Now while on the one hand it would have been a safe posting, for those who joined up to serve their country in its time of need and were desperate to do something worthwhile it must have felt like a real kick in the teeth.
