Neutrino oscillation measurement entered a precision era. In summer 2017, T2K
disfavoured CP conserving phase of δcp=0,π at 2σ level. CP asymmetry in neutrino
and anti-neutrino νμ->νe appearances can be as large as 20% depending on the CP
phase δcp, which is within the reach of new projects, HyperK and DUNE. HyperK
aims at statistical error of ~3% for the asymmetry. It is essential to control the systematic
uncertainties well below the statistical errors for the discovery. The mixing angle $θ_{23}$,
which was discovered in the atmospheric neutrino mixing, is consistent with maximal
mixing ($\sin^22θ_{23}$~1), possibly indicating μ-τ symmetry in the lepton mixing. This
result is already started to be limited by the systematic uncertainty. I will describe
essential challenges and opportunities in handling systematic uncertainties in precision
neutrino oscillation measurements, and describe emerging efforts to handle them
which are lead by the Canadian long baseline neutrino group.
