We study the capabilities of the short baseline neutrino program at Fermilab to probe the unitarity of the lepton mixing matrix. We find that the Fermilab program can improve the sensitivity to non-unitary parameter $|\alpha_{21}|$ by about one order of magnitude. Motivated by the future DUNE experiment, we have also analyzed the potential of a liquid Argon near the detector in the LBNF beamline. This will substantially improve the current sensitivity of non-unitarity.
