haha, thank you guys! I'll clarify, I did mean a crust in the traditional pie sense. The top is potato. I'm going to make one tomorrow and post pictures. Basically, you would lift it out of the casserole dish with a ladle or spoon and onto your plate.
When you cook it, when adding the beef and vegetable mix into the casserole dish, the beef is contacting directly with the edge of the panwith no flaky/moist/delicious/not delicious barrier between the beef mix and side of the dish. Once that has been added, mashed potatoes is put on top of the mix, not down any of the sides. Insert into the oven for awhile, all the deliciousness meshes together and voila, Canadian Shephards Pie.
