Yes, AutoSlash works worldwide. Note that we are seeing availability at Hetz.com for the location at 4101 Macleod Trail S in Calgary for 10/8-10/11. Of course, the rate through us is far cheaper, but it does look like it's possible to book a pay-later rate directly with Hertz if that's your wish.

If you're logged into your Hertz account, you may want to try logging out and searching again. Sometimes that can affect availability.

Note that Hertz's website is often pretty screwy, so sometimes using a private/incognito window (or clearing cookies for hertz.com) is necessary to make it work right.
