Depends how you define canon. Lucas has watched them personally and approved them. From USAToday.com:
"My son Jett (age 10) and I sat down to watch Clone Wars one weekend, and we were blown away by it," Lucas says. "I've always loved Samurai Jack, so I was curious to see what Genndy could do with Star Wars. ... It complements the movies well."
