English golfer Luke Donald has admitted that his busy schedule is "tough" on him ahead of his appearance at the Canadian Open.
Donald, who has struggled for form recently, said that it is his job as a professional to play in as many tournaments as he can in order to make them as competitive as possible.
"Ideally this tournament would be in a different slot," Donald said. "But I'm committed to my agreement with RBC and I'm committed to trying to make this championship as good as it can be, and I will be here trying my hardest.
"Obviously coming from the UK to here to a World Golf Championship to another major, it's not ideal to be playing four in a row with the PGA being the fourth and then have the run of FedExCup events.
"So it's tough. You've got to make sure you're efficient with your practice and take some days off when you can."
Donald's best Major result was being tied for third at the PGA Championship in 2006.
