The Dominion Radio Astrophysical Observatory Synthesis Telescope (DRAO ST) is being used to carry out deep imaging of the ELAIS-N1 region (R.A. = 16h 10m, DEC = +55d) in the HI 21-cm line as well as 21 cm and 74 cm continuum. Full Stokes polarimetry is obtained of the 21 cm continuum. High sensitivity will be achieved by combining eighteen closely spaced synthesis fields. At present, the ten central fields have been processed and combined to yield a maximum continuum sensitivity of 70 microJy in Stokes I and 100 microJy in Stokes Q and U, as well as 0.5 K per 0.82 km/s channel in the HI line. We present the Stokes I, Q, and U images as well as results of a source finding algorithm which has detected over 700 sources above the (local) 5 sigma level in Stokes I as well as 43 polarized sources. The detection of polarized sources to this low flux level will allow us to examine the population of faint polarized radio sources and constrain models for polarized source counts. We will also correlate the polarized sources with published catalogs (e.g. galaxies observed with the Spitzer Space Telescope).
