....was not the ony reason for not being allowed overseas. Ralph's brother, Orvil, was a CN Engineer and went to apply for the forces with Ralph but was rejected. He was considered vital to the war effort here in Canada and therefore not allowed to join. I suppose he could have quit and reapplied as unemployed, but when your government asks you to continue to support the war effort by NOT quitting your job, the dedicated individual would continue as before. Though not much respect was given those who were male, heathly and not in uniform. In some repects it could be tougher than joining, I imagine. No support of your squad, scornful looks , taunts , etc.
