If you have access to the Canadian databases at Ancestry, the 1891, 1901 and 1911 Canada census as well as the 1906 and 1916 census of Manitoba, Saskatchewan and Alberta can be searched by name there (images for all census are available).
Here is a link to the Manitoba Vital Statistics genealogy database:
http://vitalstats.gov.mb.ca/Query.phpI took a quick look and found deaths for George and Isabella Fletcher in Arthur listed. I also saw their son George's death listed as well.
I saw possible marriages in Arthur as follows:
Thomas Fletcher to Florence Jane Storey on 10 Jun 1898 (registration no. 1898,001265)
Mathew Dotchon Fletcher to Mary Matilda Atcheson on 3 Nov 1897 (registration no. 1897,001356)
Jane Hicks Fletcher to Thomas James Bonner on 21 Dec 1898 (registration no. 1898,001265)
If you wish to purchase any of the certificates in the database, the cost is $12 Canadian per registration. There is a form available at the website for ordering.
