The possibility of cancelation between different contributions to d_e, d_n and d_{Hg} has been reconsidered with special emphasis on the region that is phenomenologically interesting (intermediate values of \tan \beta and sub-TeV sfermion masses). It is found that in the range favored by electroweak baryogenesis (\it i.e., |\mu|\simeq M_1 or |\mu|\simeq M_2), \sin [\theta_\mu+\theta_{M_1}]\sim 1 can be compatible with the EDM bounds even for slepton masses below 500 GeV. Such large values of the phases promise a successful electroweak baryogenesis. The possibility of large CP-odd effects at linear collider has also been discussed.
