Do Canon DSLRs support high-speed sync, and what flash do you need?

I'm comparing Canon and Nikon entry-level DSLRs for flash use. Nikon's D3x00/D5x00 bodies do not support high-speed sync (HSS/FP flash), so I'm wondering how Canon handles this.
Do Canon EOS DSLRs such as the EOS 80D support HSS, allowing flash use above the normal sync speed (for example faster than 1/250s)? If so, what else is required?
Specifically:
- Do all Canon DSLRs support HSS, or are there exceptions?
- Do you need a Canon Speedlite, or will compatible third-party flashes also work?
- Is HSS available only with the flash on the hot shoe, or can it also work off-camera?

All current Canon EOS DSLRs, including the 80D, support High Speed Sync (some older EOS film cameras do not). Of course you must use a flash that is HSS capable and not all Canon or third party flashes made to be used with Canon cameras are HSS capable. Some of Canon's HSS capable flashes are only officially HSS capable when directly attached to the camera's hot shoe.
There is a workaround to use all Canon compatible HSS capable flashes off camera with any Canon EOS camera that supports HSS.
You can use third party radio triggers to use HSS off-camera with Canon EOS cameras and a HSS capable flash. This works because the transmitter on the camera's hot shoe makes the camera think there is a flash attached directly to the camera. The radio receiver built-in or attached to the HSS capable flash makes the flash think it is attached directly to the camera.
I use a Yongnuo YN622C-TX attached to my Canon cameras. I am able to use HSS with my Yongnuo YN685 flashes with built in YN622 radio receivers. I am also able to use a 430EX II connected to a YN-622C receiver in HSS mode.

Yes. Canon EOS DSLRs such as the 80D support high-speed sync, provided you use an HSS-capable flash and compatible triggering.
In general, Canon EOS cameras that support E-TTL/E-TTL II also support HSS. Older EOS film bodies without E-TTL are the main exception mentioned.
The camera body alone is not enough: the flash must also support HSS. Not every Canon-compatible flash does, whether made by Canon or by third parties such as Yongnuo, Metz, or Godox.
So with an 80D, you can use flash at shutter speeds faster than its normal x-sync speed (around 1/250s) if the flash and trigger setup support HSS.
Third-party flashes can work, as long as they are designed for Canon and specifically support HSS.
Off-camera HSS can also work, but compatibility matters. Some Canon flashes are only officially HSS-capable when mounted directly on the hot shoe. In practice, HSS off-camera is commonly achieved with compatible radio triggers, because the transmitter tells the camera that an HSS flash is attached.
