The possibility of cancellation between different contributions to d{sub e}, d{sub n} and d{sub Hg} is 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 (i.e., {mu}{approx_equal}M{sub 1} or {mu}{approx_equal}M{sub 2}), sin[{theta}{sub {mu}}+{theta}{sub M{sub 1}}]{approx}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 is also discussed.
