National Gallery of Canada is just one of the attractions in Downtown Ottawa, Ottawa so you might want to stop by during your trip. Why not take a stroll along the riverfront and watch the sunset while you're here? It's also full of great shops and restaurants, so you can spend the afternoon having a wander. If you want to experience more of the culture Ottawa has to offer, head to Notre-Dame Cathedral Basilica, Embassy of the United States, and Byward Market Square.
