Hi, From the Govt of Alberta Vital Statistics Registry Office - in Edmonton Alberta
The cost aprox $40 - access may depend on relationship -
Posting the name/s of persons you are researching - might bring some success - from family members - or those associated - they may have some information.
Alberta does not give access / index - to Births/ Marriage/ Death - Registrations / Long form Certificates
If you know the religion that the family followed - Church records / Baptism - might be available
Search Canada Census 1911 - 1916 - you may find the family / child - which will give you an aprox year of birth
Cheers, Stella
