In the Google search console, you can have alerts related to canonical URLs.
This is especially the case when the same page is accessible from multiple URLs, or when several pages have very similar content and you want to link them to a canonical URL.
This field will help you solve this problem by defining the canonical URL of the page.
If you don't do this, Google will choose a canonical URL itself and other pages that it considers to have very similar content will be crawled less often. Ideally, define yourself what is the canonical URL of the page you are editing.
Please check the dedicated page.
