We present an XMM-Newton observation of the highly polarized low-surfacebrightness supernova remnant G107.5-1.5, discovered with the Canadian GalacticPlane Survey (CGPS). We do not detect diffuse X-ray emission from the SNR andset an upper limit on the surface brightness of ~2 x 10^30 erg arcmin^-2 s^-1,at an assumed distance of 1.1 kpc. We found eight bright point sources in thefield, including the ROSAT source 1RXS J225203.8+574249 near the centre of theradio shell. Spectroscopic analysis of some of the embedded point sources,including the ROSAT source, has been performed, and all eight sources are mostlikely ruled out as the associated neutron star, primarily due to counterpartbright stars in optical and infrared bands. Timing analysis of the bright pointsources yielded no significant evidence for pulsations, but, due to the timingresolution, only a small part of the frequency space could be searched. Anadditional ten fainter point sources were identified in the vicinity of theSNR. Further X-ray observation of these and the region in the vicinity of theradio shell may be warranted.
