Full TV and streaming details are below and it's also free in many other places - plus wherever you are, you can watch the show just like you would at home with the help of a good VPN.

Warning: spoilers for Supernatural season 15, episode 19 exist below. Scroll down for our spoiler-free guide to watching Supernatural in countries all over the world.

Supernatural made its debut back in 2005 on current host channel The CW's predecessor, The WB. Fans will be treated a one-hour special retrospective before the last ever episode is broadcast, and while the show seemingly wrapped up its main storyline in episode 19, 'Inherit the Earth', the synopsis for episode 20 'Carry On' promises us: "...a final ride for saving people and hunting things". Intriguing!

Inherit the Earth saw Chuck defeated at last, with Jack having absorbing his powers and therefore able to heal Dean and Sam before ascending to a higher plane. The camera stops rolling with the brothers drinking to old friends and those lost along the way, which is really all you can ask for when you've spent a good part of your life fighting God, Lucifer, and various other primordial powers.

It was a satisfyingly conclusion, with the only real question left unanswered being: where will the show's final ever episode take us? We're about to find out. Read on as we explain how to watch Supernatural season 15 online and stream the series finale free just after it airs on TV.

Canadians can see how things pan out for the Winchester brothers in tandem with the US, as <a href="https://www.ctv.ca/" data-link-merchant="ctv.ca"" target="_blank" rel="nofollow">CTV will also be airing the Supernatural series finale on Thursday November 19 at 9pm ET/PT.
