Kathleen gave you the index entry for her death, but familysearch.org has a fuller entry. I don't know what info you are hoping to find from an obit but maybe this will help a bit. Also, if you are near to a Mormon Library you could request the film and then will be able to see the full death record.When I was in Salt Lake city I checked out a number of my ancestors who died in B.C. and the records had a lot of good info in them.There are many Mormon libraries around so if one near you might be worth looking into.

familysearch.org is a free site. ALso listed there I found a William Johnson Dyer born Sept. 25, 1888 died Jan. 18, 1966, he is son of William Dyer and Rebecca Wilson so brother to Muriel. He is listed as single.
familysearch.org also has the probate estate file for Rebecca which you can look at for free - she died Aug. 10, 1930 in Saskatchewan . It mentions those surviving her as William Dyer, Olive Flynn, Lawrence Dyer, William Dyer, Murriel Flynn, Dalton Dyer, Aylmer Dyer and George Dyer. Apparently she did not leave a will - oaths were taken by William, Dalton and John Flynn (who signed as Jack Flynn) It also has a list of the property and who it went to. Looks like her husband William got 1/3 of her estate and the other 2/3 divided between he children - I think this is because there was no will and this is how the government would divide it up. There are 32 pages in total for her estate record. The records only go to 1931 so if Wm. died after that it would explain him not being shown.
