Murray, bidding for his third ATP title, won the tiebreak 7-2 after the opening set went with serve.
The players traded breaks in the second set before Murray wrapped up the win on his first match point on Canas' serve.
"The key was my serve," Murray told a news conference. "I did not have a single break point against me until late in the match.
"This was a test. I now feel I'm getting close to my best level."
Robredo and Murray have met only once, with the Spaniard winning 6-2, 6-2 in the Los Angeles Open final last year.
