You may be tempted to drive the Cabot Trail in just one day since it's only 298km in length, but I strongly advise against this! There are so many beautiful sights to see and outdoor activities. With over 26 hikes inside the park, you could easily spend weeks here hiking alone. I spent a week in Cape Breton, mostly on the Cabot Trail, and still didn't do everything I wanted. I recommend spending at least 3-5 days driving the Cabot Trail.
