Canada's most diverse metropolis, Montréal, is an island city that favors style and elegance over order or even prosperity, a city where past and present intrude on each other daily. In some ways it resembles Vienna—well past its peak of power and glory, perhaps, yet still vibrant and grand.But don't get the wrong idea. Montréal has always had a bit of an edge. During Prohibition, thirsty Americans headed north to the city on the St. Lawrence for booze, music, and a good time, and people still come for the same things. Summer festivals celebrate everything from comedy and French music and culture to beer and fireworks, and, of course, jazz. And on those rare weeks when there isn't a planned event, the party continues. Clubs and sidewalk cafés are abuzz from late afternoon to the early hours of the morning. And Montréal is a city that knows how to mix it up even when it's 20 below zero. Rue St-Denis is almost as lively on a Saturday night in January as it is in July, and the festival Montréal en Lumière, or Montréal Highlights, enlivens the dreary days of February with concerts, balls, and fine food.Montréal takes its name from Parc du Mont-Royal, a stubby plug of tree-covered igneous rock that rises 764 feet above the surrounding cityscape. Although its height is unimpressive, "the Mountain" forms one of Canada's finest urban parks, and views from the Chalet du Mont-Royal atop the hill provide an excellent orientation to the city's layout and major landmarks.Old Montréal is home to museums, the municipal government, and the magnificent Basilique Notre-Dame-de-Montréal within its network of narrow, cobblestone streets. Although Montréal's centre-ville, or Downtown, bustles like many other major cities on the surface, it's active below street level as well, in the so-called Underground City–-the underground levels of shopping malls and food courts connected by pedestrian tunnels and the city's subway system, or métro. Residential Plateau Mont-Royal and trendy neighborhoods are abuzz with restaurants, nightclubs, art galleries, and cafés. The greener areas of town are composed of the Parc du Mont-Royal and the Jardin Botanique.

Québec City's alluring setting atop Cape Diamond (Cap Diamant) evokes a past of high adventure, military history, and exploration. This French-speaking capital city is the only walled city north of Mexico. Visitors come for the delicious and inventive cuisine, the remarkable historical continuity, and to share in the seasonal exuberance of the largest Francophone population outside France.The historic heart of this community is the Old City (Vieux-Québec), comprising the part of Upper Town (Haute-Ville) surrounded by walls and Lower Town (Basse-Ville), which spreads out at the base of the hill from Place Royale. Many sets of staircases and the popular funicular link the top of the hill with the bottom. Cobblestone streets, horse-drawn carriages, and elaborate cathedrals here are charming in all seasons. The Old City earned recognition as an official UNESCO World Heritage site in 1985, thanks largely to city planners who managed to update and preserve the 400-year-old buildings and attractions without destroying what made them worth preserving. The most familiar icon of the city, Fairmont Château Frontenac, is set on the highest point in Upper Town, where it holds court over the entire city.Sitting proudly above the confluence of the St. Lawrence and St. Charles rivers, the city's famous military fortification, La Citadelle, built in the early 19th century, remains the largest of its kind in North America. In summer, visitors should try to catch the Changing of the Guard, held every morning at 10 am; you can get much closer to the guards here than at Buckingham Palace in London.Enchanting as it is, the Old City is just a small part of the true Québec City experience. Think outside the walls and explore St-Roch, a downtown hot spot, which has artsy galleries, foodie haunts, and a bustling square. Cruise the Grande-Allée and avenue Cartier to find a livelier part of town dotted with nightclubs and fun eateries. Or while away the hours in St-Jean-Baptiste, a neighborhood with trendy shops and hipster hangouts.

Sitting on the natural junction where the River Saguenay unloads into the massive Saint Lawrence, a visit to strategically located Tadoussac leaves you fantastically placed to explore some of Quebec's finest history, wildlife and scenery. Sail a little further up the Saguenay, and you’ll be confronted by the glorious Saguenay Fjord, as you cruise through verdant hills of dense forestry, and steep cliffs. Or, alternatively, voyage out onto the deep waters of the Saint Lawrence river, where you can spot the surface parting, as the world's largest animals - blue whales - slowly emerge from the depths to gulp in air. With a fantastic supply of krill to tempt the whales, you can even spot the various species that visit from Tadoussac’s shoreline – just make sure you brush up on your whale knowledge beforehand, at the Marine Mammal Interpretation Centre.The town was the first trading post established by the French when they landed here, and it remains the oldest of the settlements still in existence. As the name suggests, Tadoussac's Old Chapel, has an impressive history, and is North America's oldest wooden chapel. You wouldn't necessarily know it from the outside, however, as the charming little church gleams tidily with a fresh lick of cherry red and white paint.

Designated as the Island capital in 1765, Charlottetown is both PEI’s oldest and largest urban center. However, since the whole "metropolitan" area only has a population of about 65,000, a pleasing small-town atmosphere remains. The city is a winner appearance-wise as well. Peppered with gingerbread-clad homes, converted warehouses, striking churches, and monumental government buildings, Charlottetown’s core seems relatively unchanged from its 19th-century heyday when it hosted the conference that led to the formation of Canada. The city is understandably proud of its role as the "Birthplace of Confederation" and, in summer, downtown streets are dotted with people dressed as personages from the past who’ll regale you with tales about the Confederation debate.

If you come directly to Cape Breton via plane, ferry, or cruise ship, Sydney is where you’ll land. If you’re seeking anything resembling an urban experience, it’s also where you’ll want to stay: after all, this is the island’s sole city. Admittedly, it is not the booming center it was a century ago when the continent’s largest steel plant was located here (that era is evoked in Fall on Your Knees, an Oprah Book Club pick penned by Cape Bretoner Anne-Marie MacDonald). However, Sydney has a revitalized waterfront and smattering of Loyalist-era buildings that appeal to visitors. Moreover, it offers convenient access to popular attractions in the region—like the Miner’s Museum in nearby Glace Bay (named for the glace, or ice, that filled its harbor in winter), the Fortress at Louisbourg, and beautiful Bras d'Or Lake.

There’s history and culture around every bend in Boston—skyscrapers nestle next to historic hotels while modern marketplaces line the antique cobblestone streets. But to Bostonians, living in a city that blends yesterday and today is just another day in beloved Beantown.
