  The 4-m International Liquid Mirror Telescope (ILMT) will soon become
operational at the newly developed Devasthal observatory near Nainital
(Uttarakhand, India). Coupled with a 4k $\times$ 4k pixels CCD detector and TDI
optical corrector, it will reach approximately 22.8, 22.3 and 21.4 magnitude in
the $g'$, $r'$ and $i'$ spectral bands, respectively in a single scan. The
limiting magnitudes can be further improved by co-adding the consecutive night
images in particular filters. The uniqueness to observe the same sky region by
looking towards the zenith direction every night, makes the ILMT a unique
instrument to detect new supernovae (SNe) by applying the image subtraction
technique. High cadence ($\sim$24 hours) observations will help to construct
dense sampling multi-band SNe light curves. We discuss the importance of the
ILMT facility in the context of SNe studies. Considering the various plausible
cosmological parameters and observational constraints, we perform detailed
calculations of the expected SNe rate that can be detected with the ILMT in
different spectral bands.
