At the Tokyo Olympics in 2021 Morrison and McIntyre won their heat in the pair and two hours later backed-up in the four with Rosie Popa and Lucy Stephan to hold out a fast finishing Irish crew for another heat victory, setting a new Olympic best time in the process. Four days later in the final of the coxless four they led from the start, were challenged hard to the finish by the Dutch crew but took the gold in another Olympic best time. Two days rowing at the Olympic regatta were lost due to bad weather and in the reshuffled schedule Morrison and McIntyre's semi-final in the pair started less than two hours after the medal ceremony for the four. The girls were challenged in the semi and although they finished less a second behind the winning Greek pair, they were in fourth place and missed the cut of the A final. Morrison and McIntyre won the petite final the next day for an overall seventh place in the coxless pair at the Olympic regatta.
