Hi, I searched the Provincial Archive of BC Vital Events index and found the following

Betty Elizabeth Pearson Age:86 Event:Death
Place Burnaby Date:1986 11 25 (Yr/Mo/Day)

This is the only Betty Pearson - dcd in Burnaby BC
there are are other Betty Pearson listings dcd elsewhere in B.C.
I can take a look at this reg. as well an obituary next time I am in town.
