Yeah. According to Hostgator, they are working on adding it. But you never know how much time it will take.
I switched from HG to SiteGround a few days ago, by just following suggestions of our beloved members here. And it is great! I am never looking back to HG or Bluehost!
If your hosting subscription is ending, I would advise you the same. Go for SiteGround, plus there's a 60% discount right now. Not only you will get one year free SSL, but they will also migrate your website for free. And once, your normal SSL ends after an year, you can always opt for Let's Encrypt.
