We present the latest result of our W-band survey with CFHT/WIRCam. Substellar
candidates were selected with J-, H-, and W-band photometry. We tested our selection criteria with a sample of substellar objects and stars in IC348 and Taurus and found the
accuracy to be better than 75%. Using the JHW photometry alone, two new L-type
objects in Serpens have been confirmed in spectroscopic followup this July.
More candidates in Taurus are going to be observed with IRTF followup in the
end of December. The spectra of observed candidates will also be presented in
this talk.
