We present a study of strain modulation effects on electronic structures of a two-dimensional single-band chiral p-wave superconductor within the BCS mean-field scheme. We employ a lattice model and numerically solve the corresponding Bogolyubov-de Gennes equations. Assuming that strain modulation only modifies hopping amplitudes, we observe the emergence of local spontaneous supercurrents that are attributed to the non-trivial band topology of the system. We also report that strain modulation could induce the formation of topologically distinct domains within a single system, which is captured by spectral functions and local Chern markers.
