The R3 was revealed 7 years later than the A7R and that is a fairly serious difference as far as camera technology is concerned. Both cameras have the same body design (SLR-style mirrorless).

Before going straight to a in depth comparison, here is a short summation of how the R3 scores versus the A7R in terms of portability, imaging, features and an overall grade.

Here is a sample of the gallery pictures for Canon EOS R3 & Sony Alpha A7R. The full galleries are provided at Canon R3 Gallery & Sony A7R Gallery.

In case you're planning to lug around your camera, you will want to consider its weight and proportions.

More often than not, it is very difficult to see the contrast in sensor measurements just by going through technical specs. The photograph underneath should offer you a better sense of the sensor sizing in the R3 and A7R.

As you have seen, both of those cameras provide the same sensor dimensions but not the same megapixels. You can anticipate the Sony A7R to produce more detail because of its extra 12 Megapixels. Greater resolution will help you crop images more aggressively. The newer R3 is going to have an edge in sensor tech.
