Colonialism and space

For the fourth week, Professor Morningstar brings two maps and lays them side by side on the table. The first is a survey plan of the city from the 1870s, ruled into perfect squares that run straight over the rivers and the creek beds. The second is a hand-drawn map made recently by Elders of Treaty 1 nations and Métis families, showing trails, gathering places, river crossings, burial grounds and the names of places in their languages. 'Both of these are maps of the same land,' she says. 'One was made to divide it and sell it. The other was made to remember it. Architects and planners have mostly worked from the first kind of map. This week we look at what that has meant.' Joon-ho asks which map is more accurate. The professor smiles. 'Accurate about what?'

Colonialism is the process by which one people takes control of another people's land, government, economy and culture. Settler colonialism, the form that shaped Canada and the United States, is distinct because the colonizers came to stay: its goal was not only to rule Indigenous peoples but to replace them on the land. Space was central to this process. Land was surveyed, divided, sold and built on; Indigenous peoples were confined to small reserved areas; and towns, roads and buildings made the new order permanent. This lesson examines how colonialism worked through space and architecture, and how communities are reclaiming land and place today.

Doctrines of discovery and empty land

European colonial powers justified taking land in the Americas with legal ideas developed in the fifteenth and sixteenth centuries. The Doctrine of Discovery, grounded in papal bulls of the 1450s and 1493, held that Christian nations could claim lands not ruled by Christians. The related idea of terra nullius, land belonging to no one, treated land that was not farmed or built on in a European way as empty, ignoring the nations who lived on, managed and governed it. In 1823 the United States Supreme Court, in Johnson v. M'Intosh, adopted the Doctrine of Discovery into American law, and Canadian courts long relied on similar ideas. In 2023 the Vatican formally repudiated the doctrine, and both countries have begun to reject it in law and policy.

These ideas had an architectural consequence: they made Indigenous building invisible. A village of wiigiwaams, a seasonal camp or a managed landscape of berry patches and burned prairie did not count as occupation in European eyes, while a fenced field and a log house did. The history of architecture you learned in school, which mostly begins in North America with the colonial church and the settler farmhouse, repeats this blindness.

Treaties and the land

In what is now Canada, the Royal Proclamation of 1763 recognized that Indigenous nations held rights to their lands, which could be acquired only by the Crown through agreements. After Confederation, Canada negotiated the numbered treaties across the West and North between 1871 and 1921. Treaty 1 was signed on 3 August 1871 at Lower Fort Garry, north of Winnipeg, between the Crown and the Anishinaabe and Swampy Cree nations of the region. Winnipeg stands on Treaty 1 territory and in the homeland of the Métis Nation. The written text of the treaties described the surrender of land in exchange for reserves, annual payments, schools and farming help; many First Nations understood them as agreements to share the land in peace while keeping their ways of life, an understanding recorded in their oral histories and now increasingly recognized by courts.

A stylized map of the land around the two rivers. In the background, a straight grid of square townships and sections runs across the whole map. Overlaid on it are curving trails, river crossings and gathering places marked with circles, and a band of long narrow lots running back from the river banks. A small fenced square marks a reserved area far from the river.
Two ways of dividing land. The survey grid ignored rivers, trails and existing communities; the earlier patterns followed the land. Stylized, not drawn to survey accuracy.

The grid and the survey

The survey grid was the most powerful spatial tool of settler colonialism. In the United States, the Land Ordinance of 1785 created the Public Land Survey System, which divided the western territories into townships six miles square, each split into thirty-six sections of one square mile. In Canada, the Dominion Lands Survey, begun in 1871, used a similar system of townships and sections across the Prairies. The grid turned land into a commodity that could be described on paper, sold from afar and registered in a title office. It ignored rivers, hills, trails and existing communities, and it remains visible today in the straight roads and square fields of the Prairies and the Plains and in the street grids of their cities.

The grid collided with older patterns. Along the Red and Assiniboine rivers, Métis families had farmed long, narrow river lots that gave each household access to water, a strip of farmland and woodlot behind. When Canadian surveyors arrived in 1869 to lay out square townships, the Métis feared for their land, and the conflict became one of the causes of the Red River Resistance led by Louis Riel. The river lot pattern still shapes some Winnipeg streets. Across the continent, the grid similarly overrode the village plans and field patterns of Indigenous nations and of earlier French and Spanish settlers.

Reserves, reservations and confinement

As settlers took land, Indigenous nations were confined to small reserved areas. In Canada, reserves were set aside under the treaties and the Indian Act of 1876, which gave the federal government sweeping control over the lives of First Nations people. Reserves were often on poor land far from traditional territories. From 1885 into the 1940s, the pass system, which had no basis in law, required First Nations people on the Prairies to obtain permission from an Indian agent to leave their reserves. Life on reserved land was shaped by government plans: houses built to standard designs, laid out on grids or along roads, with a church, an agent's house and a school set in positions of control.

The most damaging institutions were the schools. For more than a century, the federal government and churches ran residential schools, which about 150,000 First Nations, Inuit and Métis children were forced to attend, far from their families, forbidden to speak their languages. The last closed in 1996. The Truth and Reconciliation Commission, in its 2015 report, called the system cultural genocide, and in 2021 the confirmation of unmarked graves at former school sites brought the history to national attention. The school buildings were designed to impress and control: large, symmetrical brick buildings in classical or Gothic styles, with dormitories, chapels and supervision built into the plan. Many survivors and communities now decide what should happen to these buildings: some have been demolished, some preserved as places of memory, and some reclaimed for new uses by the nations themselves.

Erasure in the city

Colonialism also shaped cities. Indigenous people were largely excluded from urban life for much of the twentieth century, and the communities that formed at city edges were often removed. In Winnipeg, Rooster Town, a Métis community on the southwestern edge of the city, grew from about 1901 and was cleared in 1959 to make way for a shopping mall and a high school. As you saw in ARCH-340, similar removals destroyed Africville in Halifax and Hogan's Alley in Vancouver. The names of places changed too: Indigenous names were replaced with the names of settlers, kings and generals, and Indigenous presence was reduced to a few statues and street names, often stereotyped.

Infrastructure carried colonial relationships as well. A striking example is Shoal Lake 40 First Nation, on the Manitoba–Ontario border. To build the aqueduct that has carried Winnipeg's drinking water from Shoal Lake since 1919, the community's land was cut off by a channel, leaving it on an artificial island without a road and, for decades, without safe drinking water of its own. A road, which the community calls Freedom Road, was completed in 2019, and a water treatment plant followed. For architects and engineers, such cases are reminders that infrastructure decisions about water, roads and energy have often been made at the expense of Indigenous communities.

Reclaiming space

Indigenous nations are reclaiming land and place through many routes. The movement often called Land Back seeks the return of land and decision-making to Indigenous nations. Treaty land entitlement and land claims settlements have returned land to some nations, and some of that land is in cities. In Winnipeg, Long Plain First Nation created an urban reserve on Madison Street, and Naawi-Oodena, on the former Kapyong Barracks, is 109 acres jointly owned by seven Treaty One Nations, with close to 5,000 homes planned, as you saw in ARCH-340. Co-management agreements give nations a role in parks and protected areas, and Indigenous place names are being restored on maps and signs.

Architecture plays a part. New buildings designed by and with Indigenous communities, such as those you met in Lesson 3, change the face of cities. Land acknowledgements, now common at public events, can be a beginning, but many Indigenous people point out that an acknowledgement without action is empty. For architects, more meaningful steps include learning the history of a site before designing on it, involving the nations whose land it is, supporting Indigenous designers and recognizing Indigenous presence in the design itself, in names, landscapes, materials and spaces, when the nations wish it.

Worked problem

Reading a site's colonial history

Wren's studio site is a vacant lot by the river. The survey shows a rectangular parcel on the city grid. How should she investigate its history before designing?

Show solution
  1. Find the nations whose traditional territory includes the site and the treaties or agreements that apply.
  2. Look at historical maps and photographs to see what was there before the grid: trails, river crossings, villages, river lots or gathering places.
  3. Check for any record of earlier communities that were removed, and of burial or archaeological sites, which may require consultation.
  4. Contact the relevant nations or Indigenous organizations to ask whether the site has meaning for them and whether they wish to be involved.
  5. Record what she learns and let it shape the design brief, from orientation and landscape to program and naming.

Answer: Wren discovers that the lot lies beside an old river crossing used for centuries. With the community's guidance, her design keeps a view and a path to the crossing open, instead of building across it.

Exercise 4: two maps

This exercise takes about four hours.

  • Choose a district of your city and find the earliest survey or subdivision plan you can.
  • Using sources from Indigenous nations, historical societies and archives, map what existed before and what was lost or changed.
  • Overlay the two maps and mark at least three places where the grid overrode an earlier pattern.
  • Deliverable: the overlay map and a 600-word essay on what the comparison reveals and what an architect working in the district should do with this knowledge.

Self-critique checklist

  • Have I used Indigenous sources as well as government records?
  • Have I distinguished the written terms of treaties from the understanding of the nations that signed them?
  • Have I avoided presenting colonialism as finished history?
  • Have I proposed actions, not only acknowledgements?

Colonial space in everyday buildings

Colonial patterns also survive in ordinary places that architects design every day. Public buildings in many cities still present their grandest face to the street grid and their backs to the river, reversing the older relationship in which rivers were the main routes and gathering places. Parks and monuments often commemorate settlers, soldiers and officials while saying nothing of the nations whose land they occupy. Street names, school names and even the names of rooms in public buildings carry the same history. Reviewing these choices is part of an architect's work on any public project: which way does the building face, whose history does it tell, and whose is missing?

Planning rules can carry colonial assumptions too. Zoning that permits only single-family houses on large lots, minimum lot sizes, limits on the number of unrelated people who may share a house and bans on outdoor fires or on keeping and preparing game can make it difficult for Indigenous families to live in cities in ways that suit their cultures. Some cities have begun to review their bylaws with Indigenous communities, and architects can support these reviews by documenting how existing rules affect the people they design for.

Common mistakes

  • MistakeTreating land before settlement as empty.

    InsteadIndigenous nations lived on, managed and governed the land; seeing it as empty was a legal fiction used to take it.

  • MistakeReading treaties only through their written text.

    InsteadMany nations understood the treaties as agreements to share land, and their oral histories record those terms.

  • MistakeThinking of the survey grid as neutral.

    InsteadIt was a tool that turned land into property and overrode existing communities and patterns.

  • MistakeEnding with a land acknowledgement.

    InsteadAn acknowledgement is a beginning; learning, involvement and action give it meaning.

Summary and key terms

Practice problems

Work each problem on paper first, then reveal the answer to check.

  1. What distinguishes settler colonialism from other forms of colonialism?

    Show answer

    The colonizers come to stay and seek to replace the Indigenous population on the land, not only to rule it.

  2. How did the survey grid serve colonization?

    Show answer

    It turned land into parcels that could be described, sold and registered from afar, ignoring existing communities and patterns.

  3. Why did the Métis river lots conflict with the Canadian survey?

    Show answer

    The river lots were long narrow strips fronting the rivers, while the survey imposed square townships, threatening Métis land holdings.

  4. Why were residential and boarding school buildings designed as large, symmetrical institutional buildings?

    Show answer

    To impress and control, with supervision, dormitories and chapels built into their plans.

  5. Name two ways nations are reclaiming space today.

    Show answer

    For example, land returns and urban reserves, restoring place names, building their own institutions and leading the design of new buildings.
