We are using Yoast for a number of our sites.  We use naked domain as the canonical. I have noticed in the header tags that all our sites show the canonical URLs as having a trailing slash:

Example:   http;//foxspizzajc.com, when I look at the source code, it shows the canonical as http;//foxspizzajc.com/

Of course, it is much more likely that all sites that link to us will not use the trailing slash - so preferably we do not want that to be the canonical - among other reasons.

Does this need to be fixed so the trailing slash is removed? I cannot see how to do this in Yoast SEO or in Permalinks structure for Wordpress.

Sorry for my ignorance.

Thanks for any help.
