GG 250- Geography of Canada
Canada’s Regions: Concepts and Themes
Regional Geography concerned with three things:
Detailed description of region
The interpretation of distribution patterns (patterns associated with
one or more selected characteristics which define the region)
The relationships among the characteristics that are within the
region
Essentially two basic approaches in Regional Geo.
First is the Regional approach
Other is Topical approach.
A. Regional Concepts
What is a Region?
an area of the earth’s surface differentiated by one or more
features which provide it with internal unity and distinguish it from
surrounding areas.
Regions are therefore human constructs. They provide us with meaningful
framework. A framework we can use to apply to similar features or similar
parts of the world.

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

Regions are sufficiently unified:
We are aware of their distinctive characteristics.
We are also aware of their spatial dissent.
You can define a region at different geographical scales…
Three types of regions:
Mega regions (large sized, and applied at the global scale) eg. A
Continent.
Meso regions (medium sized, are applied at the national scale) eg.
Parts of countries like great lakes.
Micro regions (small sized, applied at the local scale) eg. Could be
part of a region or city like GTA.
There are many numerous criteria that can be used to set up the
boundaries, most common are:
Define a region according to physio-graphical boundaries. Eg Rocky
mountains
You can define a region on political boundaries. Eg, borders of a
province.
Define a region by perception. Eg. Cottage country, which may not
mean the same thing to you as others.
B. Common Characteristics of a Region
There are Four:
oAll regions have a location. (occupy a certain part of earths
surface)
oAll regions have area. (it does not matter how wide or narrow
all cover a certain part)
oAll regions have boundaries. (they all have limits)

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

oAll regions occupy a position within a hierarchy. (We can have
regions within regions)
All regions have three basic components:
1. A core: The highest concentration of the distinguishing feature (language
spoken for eg).
2. The domain (semi peripheral): The intensity of the distinguishing feature
is less intense than the core.
3. The Peripheral: Not a clear limit of distinguishing feature.
Four types of Regions:
Formal regions: Also known as a uniform region.
oDefined as an area differentiated by the essential
homogeneity of the distinguishing feature. (Distinguishing
feature is entirely absent, or entirely present. Eg. Only French
speaking individuals nothing else in the region)
oMost formal regions are defined on human characteristics.
Boundaries of this formal region very rarely coincide with
natural regions. In terms of boundaries they tend to be very
stable for long periods of time.
Functional Regions :
oDefined as an area differentiated by linkages (intensive
interactions/flows) among its heterogeneous yet
interdependent features which contribute to the activity within
it.
oUsually applied as a spatial system as there are connections
and interactions. This region will have a core area. City region
is probably the best example of a functional region, such as
GTA.
oBoundaries can be stable but at the same time they can be
dynamic. There is no guarantee for long term stability
