A Steve Wusyk is on 1949 voter's list in Edmonton Alberta, 1963 and 1965 and 1974 in Athabasca Alberta.
Having looked at the marriage registration I would say that that was your Steve.
Try Canada411. There are 6 Wusyks listed in Alberta.
There is a headstone in Lakeview Cemetery in Cold Lake Alberta for a Steve Wusyk but it gives birth as 1916.
Have a look on
http://www.rootsweb.ancestry.com/~cangmg/alberta/bonnyvil/co...Don't know much about Alberta records but Ontario births are only released to 1914; marriage to 1929 and deaths to 1940.
It doesn't appear that Alberta vital stats are on line.
