If the Wilderness FA certificate is a St. John Ambulance certificate then yes. This is because the SJA Wilderness FA course is based on the Standard FA course.
If the Wilderness FA certificate is from a different agency then no. The focus may be too different between the two courses.
Most likely the student won’t be able to take the SFC Recert unless they came from Alberta. We have not offered the Wilderness FA course for a decade plus.
I am copying Anita (as an FYI) so that she is aware about the relationship between Wilderness FA and Standard FA.
