The 53-year-old man pleaded guilty to the charges last September and was sentenced Thursday in court in Lethbridge.
Court heard the man sexually assaulted his two daughters over an extended period.
Judge Derek Redman called sexual abuse of children "a heinous crime."
The man was given credit for 25 months served in pre-trial custody.
When the man was taken away, his older daughter screamed an obscenity at him.
