It's a substitution cipher encoding coordinates for a point outside Saskatoon (52.069N, 106.3892W).

It literally turns out to be
"north five two zero six nine zero zero west one zero six three eight nine two zero" and I just guessed at the decimal separators. But the longitude has an extra digit, which implies it ought to be (0.5N, 1.0W), (5.2N, 10.6W), or (52N, 106W), and the other points are over water. If you ignore the precision, you can also derive points in Ghana and the British Isles.
