We present an XMM-Newton detection of two low radio surface brightness SNRs,G85.4+0.7 and G85.9-0.6, discovered with the Canadian Galactic Plane Survey(CGPS). High-resolution XMM-Newton images revealing the morphology of thediffuse emission, as well as discrete point sources, are presented andcorrelated with radio and Chandra images. The new data also permit aspectroscopic analysis of the diffuse emission regions, and a spectroscopic andtiming analysis of the point sources. Distances have been determined from HIand CO data to be 3.5 +/- 1.0 kpc for SNR G85.4+0.7 and 4.8 +/- 1.6 kpc for SNRG85.9-0.6. The SNR G85.4+0.7 is found to have a temperature of ~12-13 MK and a0.5-2.5 keV luminosity of ~1-4 x 10^33 D(3.5)^2 erg/s (where D(3.5) is thedistance in units of 3.5 kpc), with an electron density n_e of~0.07-0.16(fD(3.5))^-1/2 cm^-3 (where f is the volume filling factor), and ashock age of ~9-49(fD(3.5))^1/2 kyr. The SNR G85.9-0.6 is found to have atemperature of ~15-19 MK and a 0.5-2.5 keV luminosity of ~1-4 x 10^34 D(4.8)^2erg/s (where D(4.8) is the distance in units of 4.8 kpc), with an electrondensity n_e of ~0.04-0.10(fD(4.8))^-1/2 cm^-3 and a shock age of~12-42(fD(4.8))^1/2 kyr. Based on the data presented here, none of the pointsources appears to be the neutron star associated with either SNR.
