In the present paper, firstly we obtain the canal hypersurfaces that are formed as the envelope of a family of pseudo hyperspheres or pseudo hyperbolic hyperspheres whose centers lie on a spacelike curve with parallel timelike normal vector field B₂ in Minkowski space-time and we give some geometric characterizations for them by obtaining the Gaussian curvature, mean curvature and principal curvatures of these canal hypersurfaces. Also, we give the general expression of parametrizations of the canal hypersurfaces generated by non-null curves with parallel frame in E₁^4 and we obtain some important geometric invariants and characterizations for them.
