On The Rise, page-59

Hi everyone,
Im hoping someone could help me. I held BLR shares up until they were delisted and taken over by WUC in 2015. I received a letter something with the amount of shares i had and where they went. Unfortunately i forgot about them and didnt chase it up on the Canadian Stock exchange. Even worse than that in a recent move i lost that letter.
Is there anyone that would be able to help me trace them? Ive tried contacting computershare, NAB (which they were traded on), delisted.com and noone can seem to help me. Any assistance would be enormously appreciated.
