In sentencing, Judge McGuire said Sidhu still maintained his innocence and was considered an "untreated and unrepentant sexual offender". He said Sidhu told a probation officer the victim had flirted with him.
"Given [the] evidence in court about that night I cannot completely rule that out as a possibility. The fact remains that if at the time sexual intercourse occurred a complainant is not consenting and you have no reasonable grounds to believe she is, you commit rape."
The judge said Brar, who needed a Punjabi translator during the court process, was more likely to have held an unreasonable belief the victim had consented. Brar had taken his cues from Sidhu during the rape and had told a probation officer Sidhu informed him the woman had consented.
Judge McGuire said the woman's victim impact statement was "harrowing".
"You preyed upon a vulnerable, intoxicated person in the early hours of the morning," he told the men. "Quite plainly you were on the lookout to see if you could pick up a woman or women ... and you did that."
Brar's wife was in court to support him while the judge was handed a letter from Sidhu's wife, with whom he has a 1-year-old son.
Crown prosecutor Chris Macklin had argued for a sentence of 10 to 11 years' jail for both men, calling the rape "calculated" and "degrading".
