  Anderson et al. (2017) identified seventy six candidate supernova remnants
(SNRs) using data from The HI, OH, Recombination line survey of the Milky Way
(THOR). The spectral index and polarization properties can help distinguish
between SNRs and H II regions, which are often confused. We confirm two SNR
candidates using spectral index data and morphology. However, we observe that
the fractional linear polarization cannot distinguish between SNRs and H II
regions, likely due to contamination by diffuse Galactic synchrotron emission.
We also comment on the association of SNR candidates with pulsars through
geometric and age considerations.
