Marriage from Manitoba Vital Stats
A Jennie Francis Coleman married Richard Anderson Tufts, 27 July 1916 at Winnipeg. Registration # 1916,039172.
The below information is from FamilySearch and Jennie/Jane's birth date doesn't fit with your Jennie's.
1906 gives a Jane Coleman, nurse in Brandon Manitoba, born Ontario so I think she is the one below.
