Yes, that is CA, but it is worth noting that there are two main types of chromatic aberration: axial (or longitudinal, LoCA), and transverse (or lateral, LCA). What you are seeing here is LoCA, which is not so easily corrected automatically.
The one-click filters in software mostly handle LCA, which is when different wavelengths of light (colors) to spread to different positions in the focal plane, but not LoCA, which causes light of differing wavelengths to be focused at different points along the optical axis (e.g., different colors are either front or back focused). You see this aberration particularly with certain very fast lenses shot at or near wide open.
For Canon images you can tackle this in two ways:
1. In Canon's Digital Photo Professional (DPP), you can use the Color Blur filter to apply a one-click automatic correction, based on an installed lens profile for a compatible Canon EF lens.
2. In Lightroom or Adobe Camera RAW, you can use Adobe's DeFringe tool to apply a manual correction. You may vary the sliders to adjust the strength and color match to get the best result. Note that this is a blunt instrument and can cause unwanted side effects elsewhere in the image if you happen to have similarly colored areas.
Hope this helps.
