  We analyze the non-unitary effects in the linear seesaw mechanism using the
current constraints and future sensitivity of the charged Lepton Flavor
Violation (cLFV) processes. We perform a random scan confronting the
non-unitary parameters with the limits to the cLFV processes. We show our
results for the normal and inverted ordering of the oscillation data. We also
discuss the equivalence of different parametrizations of the non-unitary mixing
matrix and show our results in terms of the different parameterizations. We
found that the stronger restrictions in the non-unitary parameter space come
from rare muon decay searches.
