Short answer: Yes, the Canon R6 Mark II works with modern Canon Speedlites and with major third-party flashes that explicitly support Canon E-TTL / E-TTL II on EOS R bodies. The safest path is to buy a proper Canon/C version of a TTL/HSS flash, not a generic single-pin flash that only fires manually.

Want the short buying answer? If you already know you want a recommendation instead of a compatibility explanation, go straight to the buyer guide:
Quick picks (safe buying lanes)
- Easiest OEM path: a current Canon Speedlite if you want the lowest compatibility stress.
- Best value path: a major third-party Canon-version flash system like Godox if you want better value and room to grow.
- Worst mistake to avoid: a random single-pin flash that technically fires but does not give you TTL or HSS.
Compatibility checklist (do this first)
- Buy the Canon/C version: do not assume a flash that “fits Canon” is the right version.
- Confirm TTL: make sure it explicitly supports Canon E-TTL / E-TTL II on EOS R cameras.
- Confirm HSS if you need it: not every flash that fires will give you the full feature set you expect.
- Avoid single-pin manual flashes if you want automatic flash exposure, HSS, or a cleaner long-term setup.
- Use the right shutter mode: flash use on the R6 Mark II is not the same thing as silent/electronic shutter shooting.
What most buyers should do next
- Want the easiest Canon-native answer? Buy a current Canon Speedlite.
- Want better value and easier off-camera expansion? Buy a Canon-version Godox flash.

Compatibility table (works / caveats)
| Flash / system | Works? | TTL | HSS | Notes / caveats |
|---|---|---|---|---|
| Canon Speedlite (current models) | Yes (safest) | Yes | Yes (model-dependent) | Native compatibility. Still test your exact workflow (bounce, modifiers, etc.). |
| Older Canon Speedlite models | Usually | Usually | Model-dependent | If anything acts weird, reset flash settings, clean hot‑shoe contacts, then retest in manual mode as a baseline. |
| Godox / Flashpoint system (Canon version) | Often | Usually | Usually | Great value. Keep firmware current. If you use a trigger, keep trigger + flash firmware aligned. |
| Profoto (Canon TTL/HSS models) | Yes | Yes | Yes | Premium ecosystem. Confirm your Air Remote / compatibility for your exact light. |
| Random/unknown third‑party | Risky | Unreliable | Unreliable | Often inconsistent TTL and poor documentation. Fine only if you’re intentionally buying a manual-only flash. |
If you only need manual flash
If you truly only need a flash to fire in manual mode, your options widen. But most Canon R6 Mark II buyers will be happier buying a proper TTL/HSS-capable Canon-version flash from the start, especially if they want bounce flash, easier exposure control, or room to grow.
