We present a probable host galaxy of the fast radio burst FRB 20190605C, detected by the Canadian Hydrogen Intensity Mapping Experiment. The localization was enabled by saved baseband data; the region contained one galaxy with a photometric redshift consistent with the dispersion measure of the FRB. This galaxy was identified as the most likely host with a Probabilistic Association of Transients to their Hosts probability calculation, finding a probability of association P(O∣x) = 0.913. With Prospector, we used a joint spectro-photometric fit to model stellar mass, star formation rate, metallicity, age, and a spectral energy distribution for the host candidate.
