The origin of the baryon asymmetry of the universe (BAU) is currently an active field of research. A non-zero neutron electric dipole moment (nEDM) would violate both parity and time reversal symmetry. Thus, a measurement of the nEDM using UltraCold Neutrons (UCN) will help to understand the source of BAU according to the Sakharov conditions. The project of a second generation superthermal UCN source has been developed at RCNP, Osaka, Japan. This UCN source is using a unique combination of a spallation neutron source and a super thermal method using superfluid helium. Based on the success of a prototype UCN source at RCNP, we have built a new UCN source with a higher cooling power in order to use a higher intensity proton beam line at TRIUMF (Canada). The design and construction status of the UCN facility, performance of the new UCN source and future possibility at TRIUMF, in addition to an overview of the development strategy towards a next generation nEDM measurement will be discussed.
