It is possible since 2012 with the https://en.wikipedia.org/wiki/Canon_EOS_M https://en.wikipedia.org/wiki/Canon_EOS_M . There is a first-party EF/EF-S to EF-M adapter, and all Canon DSLR lenses work on the EOS M series of cameras with full functionality (aperture, focus, IS, etc.) and zero caveats. I'm not sure what motivated your question.
