Great finding those obits RK - excellent

It helps with a time frame for Ernest.
So Ernest was still living in BC in 1969 according to Walter's obit.
Any luck with that e-mail to the nearest library ref an obit for Ivy, which might show married names of the girls
Who were the other children you have not mentioned

We know of Evelyn, Jean the 2 sons (who could still be living and one of which was not Donald E on the border crossing) We also know Leonard another son was the informant on the death certificate for his mother Ivy. Who were the other children you have not mentioned
The ancestry tree's are being specific and quoting a date of death for Ernest as 23 July 1976 (with no place or source

) - if he stayed in the same area the library might also pick something definite up for Ernest at that time - worth a shot anyway.
