National Exams, May 2014 — 04-Geom-B6, Land Use, Planning & Environmental Management. Three hours; closed book (any non-communicating calculator permitted). Format: seven questions of equal value (20 marks each); the paper directs that answering any five (5) of the seven constitutes a complete exam (100%), and the first five as they appear in the answer book are marked. All seven questions are solved in full below so the set serves as a complete study resource. Answers are framed in the Canadian planning context (Statistics Canada’s census-geography definitions; the Canadian Institute of Planners; provincial planning legislation, official community plans and regional growth strategies), consistent with the Engineers Canada / EGBC syllabus for this exam.

Gordon, Planning Canadian Communities: An Introduction to the Principles, Practice and Participants (Nelson, current ed.) — the standard Canadian reference for this exam code; I.

P.13; British Columbia Local Government Act) and representative official community plans / regional growth strategies (Metro Vancouver, the Greater Golden Horseshoe Growth Plan).
Question 4 uses the exam’s terms “urbanized area” and “metropolitan area.” In current Statistics Canada usage the closest official equivalents are the population centre (which replaced the older term “urban area” in 2011) and the census metropolitan area (CMA). The answer uses the official Canadian terms and notes the correspondence, rather than importing the U.S. Census “urbanized area” definition.

In Canada these terms have two layers of meaning: a legal/administrative meaning (what a “city” is as a municipal corporation) and a statistical meaning (how Statistics Canada delineates urban and metropolitan territory for the census). Both matter to the planner, who works within municipal boundaries but analyses functional regions.
City. Legally, a city is a municipal corporation incorporated under provincial legislation, with defined boundaries, an elected council, and delegated powers to tax, regulate land use (zoning, official plan) and provide services. City status is granted by the province and is not, by itself, a fixed population number — the population thresholds for incorporating as a “city” vary from province to province. Because municipal boundaries rarely match the built-up area, the legal city is usually only part of the real urban settlement.
Urbanized area (population centre). The statistical “urban area” — renamed the population centre by Statistics Canada in 2011 — is a continuously built-up area defined by density and population rather than by municipal boundary: a concentration of 1,000 or more persons with a population density of at least 400 persons per square kilometre. Everything outside population centres is classed as rural. Population centres are further graded as small (1,000–29,999), medium (30,000–99,999) and large (100,000+). This is the Canadian equivalent of the U.S. “urbanized area.”
Metropolitan area (CMA / CA). A census metropolitan area (CMA) is a functional region: an urban core plus adjacent municipalities that are economically and socially integrated with it, measured chiefly by commuting. A CMA must have a total population of at least 100,000, of which at least 50,000 live in the core (a population centre); a smaller census agglomeration (CA) needs a core population of at least 10,000. Neighbouring municipalities are included by commuting-flow tests: at least 50% of a municipality’s employed residents work in the core (forward flow), or at least 25% of the people employed in the municipality live in the core (reverse flow). The CMA is thus the metropolitan region — the meaningful unit for regional planning — while the “city” is only its legal centre.
| Term (Canadian usage) | Basis | Threshold |
|---|---|---|
| City | Legal municipal corporation (provincial incorporation) | Set by province; no single national figure |
| Population centre (“urbanized area”) | Continuously built-up, density-based | ≥ 1,000 persons AND ≥ 400 persons/km² |
| Census agglomeration (CA) | Functional region around a core (commuting) | Core ≥ 10,000 |
| Census metropolitan area (CMA) | Functional region around a core (commuting) | Total ≥ 100,000, of which core ≥ 50,000 |
Factors for identifying urban places and cities. An “urban place” is distinguished from a rural one by a combination of factors, not any single one:
Population size and density. The primary criterion — a threshold concentration of people (1,000) at a threshold density (400/km²). Density, not size alone, is what makes a place urban.
Economic base / non-agricultural occupations. Urban places are dominated by secondary and tertiary (manufacturing, commerce, service) rather than primary (agricultural, resource) employment; the shift out of farming is a defining marker of urbanisation.
Functional role as a central place. Cities exist to provide goods, services and administration to themselves and to a surrounding hinterland (central-place function); the size and range of services identifies the level in the urban hierarchy.
Built form and land-use intensity. Contiguous built-up development, a mixture of specialised land uses (commercial core, industrial districts, residential neighbourhoods) and supporting infrastructure characterise the urban landscape.
Legal / administrative status. Incorporation as a municipality (village, town, city) confers legal recognition, governance and the power to plan — the administrative dimension of being a “city.”
Social and cultural characteristics. Greater heterogeneity, occupational specialisation and denser interaction distinguish urban from rural society. Together these factors — demographic, economic, functional, physical, legal and social — identify a place as urban and locate a city within the settlement hierarchy.
