The Great Lakes St. Lawrence Lowlands Region
The Great Lakes St. Lawrence Lowlands Region


The Great Lakes St. Lawrence Lowland, the smallest geographical
region in Canada, involves the triangle shape assembled by Lake Ontario,
Lake Erie and Lake Huron. It is located on the southern parts of Ontario and Quebec.
The St. Lawrence River gradually begins to rise into the Canadian Shield and the
Appalachians. It was formed when faulting (cracks in the Earth's crust) created a
rift valley (a valley created when the part of land between the cracks in the Earth's
crust drops down) Then later, around the end of the Ice Age, the faults lead to the
sinking of the area around the St. Lawrence, which was then flooded by part of the
Atlantic Ocean. During the flooding, the Atlantic Ocean laid down the sediments that
provided this area with it's fertile soils.

Great Lake St. Lawrence Lowland has a rolling landscape, meaning that there
are many small hills or slopes. The land is not flat or plain. The rolling
landscape had been created mainly by glaciation.


There is a variety of vegetation in Great Lake St. Lawrence Lowland. The
soil is very fertile, thus allowing many things to be grown. Many trees
(both deciduous and conifer), such as walnut, maple, hemlock and oak
can be grown in this area. As well as this, tobacco plants, peaches,
cherries, grapes, apples, hay and many vegetables, such as carrots
and beans are found here.


Great Lake St. Lawrence Lowland's climate is a humid, continental climate, meaning
that it is a dry climate with very cold winters and very hot summers. During
the summer, the Great Lakes tend to lower the temperature. The Great Lakes
also raise the temperature in the surrounding areas in winter by storing heat.

On average, the Great Lakes St. Lawrence (Quebec region) receives the highest temperature (20 degrees celcius)
in July, therefore making it the hottest month of the year. The coldest month of the year is January, typically being
at -13 degrees celcius. Along with that, precipitation is the highest in September (approximately 120mm) and the
lowest in February (approximately 70mm). Because of the high temperatures as well as the high precipitation levels
occuring around the same months of the year, it allows for mild weather and the ease for growing fruits and vegetables.

In the Toronto, Ontario region of the Great Lakes St. Lawrence, they receive the highest temperature in July, being
about 24 degrees celcius. Their coldest month of the year is January, having approximately -7 degrees celcius.
The most precipitation received is about 85mm in August, and the least received is 40mm in both January and February.
By having both the precipitation and temperature levels being the highest at approximately the same time of the year, it also
contributes to healthy farming and mild temperatures throughout the year.


The Great Lake St. Lawrence Lowland region has rich, fertile soil for agriculture which
makes it the second largest farming area in Canada. There are many resources
in this region, such as zinc, lead, cattle and grain. Also, clay can be found which
can then assist in brick and tile manufacturing. Though all these natural resources,
their number one resource is water.
