At the time of Unification, servicemen were given a raise in pay to keep them enrolled. Signing bonuses of $200.00 were given for each year to a maximum of five that they re-enlisted for. $1000.00 in 1967 was a life changing amount, possibly worth about ten times as much in 1999 dollars. Rank was given away next; anyone who had ever had a Junior NCO course was automatically promoted to Corporal. Everyone who had 4 years of service automatically went on a new Junior Leaders Course to get him promoted to Corporal. Corporal was now a giveaway, it meant nothing as far as status was concerned, it was a shoe-in for everyone.
The problem was that at that time, Corporals were then section commanders. The actual commander now was leading a whole section of his rank peers. There was actual fighting in the ranks and discipline was poor. So another level was instituted - Senior Corporal. But that was not enough, they then introduced the "B" Corporal (indicating he had qualified Part B of the Junior NCO Course). They changed the chevrons to have a little crown sewed on over the hooks.
We took turns being B Corporals as there were now so many of us. There was no continuity and of course this was unworkable. Finally instead of putting it back to what everyone knew was workable, they developed a new appointment...Master Corporal. But who would become the Masters? It was decreed that those wearing the B Corporal crown at the time would become the appointee. New leadership qualities had to established....this took years and years to even get to the point where the right people were in charge. In the process, the rank of Corporal was destroyed in the Canadian Army. Almost the exact same thing happened to the rank of Captain.
