We present the first galaxy-galaxy weak lensing results using early data from the Canada-France-Hawaii Telescope Legacy Survey ( CFHTLS ) .
These results are based on \sim 22 deg ^ { 2 } of i ^ { \prime } data .
From this data , we estimate the average velocity dispersion for an L* galaxy at a redshift of 0.3 to be 137 \pm 11 km s ^ { -1 } , with a virial mass , M _ { 200 } , of 1.1 \pm 0.2 \times 10 ^ { 12 } h ^ { -1 } M _ { \odot } and a rest frame mass-to-light ratio of 173 \pm 34 h M _ { \odot } /L _ { R _ { c } \odot } .
We also investigate various possible sources of systematic error in detail .
Additionally , we separate our lens sample into two sub-samples , divided by apparent magnitude , thus average redshift .
From this early data we do not detect significant evolution in galaxy dark matter halo mass-to-light ratios from a redshift of 0.45 to 0.27 .
Finally , we test for non-spherical galaxy dark matter halos .
Our results favor a dark matter halo with an ellipticity of \sim 0.3 at the 2 \sigma level when averaged over all galaxies .
If the sample of foreground lens galaxies is selected to favor ellipticals , the mean halo ellipticity and significance of this result increase .
