To quote from the EU regs:
Article 5 (Cancellation)
1. In case of cancellation of a flight, the passengers concerned shall:
(a) be offered assistance by the operating air carrier in accordance with Article 8; and
(b) be offered assistance by the operating air carrier in accordance with Article 9(1)(a) and 9(2), as well as, in event of re-routing when the reasonably expected time of departure of the new flight is at least the day after the departure as it was planned for the cancelled flight, the assistance specified in Article 9(1)(b) and 9(1)(c); and
(c) have the right to compensation by the operating air carrier in accordance with Article 7,
...
section 3: An operating air carrier shall not be obliged to pay compensation in accordance with Article 7, if it can prove that the cancellation is caused by extraordinary circumstances which could not have been avoided even if all reasonable measures had been taken.
The same language is for article 6 (delay).
Article 9 is "right to care" and talks about hotel, meals, etc. It's pretty clear that right to care is always applicable in case of overbooking (article 4), cancellation (article 5) and delays (article 6).
