Quebec: the Shield, the river and the hydro

Percé, the tip of the Gaspé, low tide, the great rock standing off the beach with its arch. Jean-François Bouchard is forty-nine, a maple producer in spring, a snow-crab deckhand in summer. His daughter Élodie, fifteen, raised in Montréal, is down for the holidays with her geography textbook. He points at the hills behind town and tells her they are older than the mountains on her book's cover.

So here's the question. Quebec is the second-largest jurisdiction in Canada, and most of it is Shield. How do a river, a sheet of old rock and a great deal of falling water shape where its people make their homes, and what they make?

The 2021 Census counted eight and a half million people in Quebec, 23.0% of Canadians. 77.5% of them spoke mainly French at home, and 46.4% could hold a conversation in both official languages, the highest share of any province. Montréal is the country's second-largest metropolitan area, about 4.6 million in 2025; Québec City, the capital, about 900,000.

Now the land. The Atlas of Canada gives Quebec 1,542,056 km², second only to Nunavut, and 176,928 km² is fresh water, the most of any province. The rock comes in three pieces: the Shield to the north; the Appalachian hills south of the river, Mont Jacques-Cartier their highest; and between them the narrow St. Lawrence lowland, where most Quebecers make their homes.

Then the water. The Canada Energy Regulator says Quebec's electricity is 94% hydro, and the province is Canada's top electricity producer; in 2022 it sold 22.6 TWh to the United States, more than any other province. The James Bay rivers were developed under the James Bay and Northern Quebec Agreement of 1975, the first of the modern treaties, signed with the Cree and Inuit.

Find it on the map. The map now shows the St. Lawrence at Québec City on a Natural Resources Canada topographic sheet. Official names in Quebec are French, so learn five words: fleuve, a great river that reaches the sea; rivière, a smaller one; lac, a lake; mont, a mountain; cap, a cape. Find Fleuve Saint-Laurent and watch it narrow sharply at the city. Then find a rivière joining it.

Let's change one fact. Take away the rapids above Montréal and let the river run flat to Lake Ontario. Ocean ships would never have had to stop at the island, and the Seaway would not have needed the 7 locks it built between Montréal and Lake Ontario to climb around the drops. A flat river is a highway. A stepped river makes a city where the steps begin.

The mistake people make is thinking Quebec's mountains are the Laurentians north of Montréal. The Atlas of Canada's table puts the province's highest point in the Torngats, on the Labrador line, at about 1,650 m, and Parks Canada calls the Torngats the highest mountains in Canada east of the Rockies. The Gaspé's Chic-Chocs come next. The Laurentians are Shield, old and worn, and none of them comes near.

Here's the rule, in one breath. Second-largest by area, most of it Shield; people along one river; power from the northern rivers; and French on the map, in the census and on the street.

This week, find your own community on the Atlas of Canada and look for its French name, or, if you are in Quebec, its official English one where it has one. Then pick any lake near you on Toporama and see whether the map says lac or lake.

Next time, Ontario: the lowlands, the Shield and the far north, and how to write a six-figure grid reference.
