  IC 348 is a young (t$\sim$3Myr) and nearby (d$\sim$340pc) star forming region
in the Perseus molecular cloud. We performed a deep imaging survey using the
MEGACAM (z-band) and WIRCAM (JHK and narrowband CH${_4}$ on/off) wide-field
cameras on the Canada-France-Hawaii Telescope. From the analysis of the
narrowband CH${_4}$ on/off deep images, we report 4 T-dwarf candidates, of
which 3 clearly lie within the limits of the IC 348 cluster. An upper limit on
the extinction was estimated for each candidate from colour-magnitude diagrams,
and found consistent with extinction maps of the cloud. Initial comparisons
with T-dwarf spectral models suggest these candidates have a spectral type
between T3 and T5, and perhaps later, potentially making these among the lowest
mass isolated objects detected in a young star forming region so far.
