Throughout most of the season, he aligned with Ramsey and Maddy. He later formed a alliance with Loveita and Joel. The trio overpowered the Third Wheel alliance at the beginning of the game. Dallas was seen as a competition threat, winning 2 POV's and coming up close in several HOH competitions. In Week 5, the alliance was targeted and Dallas was evicted by a 5 to 3 vote, becoming the first male evicted.
He returned in Big Brother Canada 5 with the intention of toning down his personality. He formed a not-so-secret alliance with former nemesis Cassandra, and an alliance with Dillon and Emily. After being on the wrong side of the first vote, and failing to save an ally, he was soon targeted by the man he voted to evict. After Dillon won the POV to save himself, he was named a replacement nominee, and after a failed attempt to reunite the veterans, he was backdoored with a 12-0 vote, placing 15th.
