Canon no longer repairs that camera anymore. I would suggest looking into the EOS R series mirrorless cameras. DSLR cameras have been replaced by mirrorless cameras. Avoid the EOS M series cameras they have been discontinued. Your current EF & EF-S lenses can be adapted those cameras. Note not all adapted lenses support all features on the EOS R series.
