Ontario Insurance, Natural Disasters, and Vulnerability
The number of natural disasters related to weather has risen dramatically
in Canada as seen in the graph below. Floods and ice storms are only
two of the disasters that the Emergency Preparedness Centre has to consider.
Ontario has experienced natural disasters since 1999. One example is the flooding in
Peterborough in 2004.

ACTIVITY 1
- Name 3 of the largest disasters in last two decades in Canada. In
Ontario?
- What large natural disaster happened in Peterborough, Ontario in
2004? Approximate cost?
- How big a role does drought play in natural disasters? Hint: check
agriculture and lake levels.
ACTIVITY 2 Research
- List the top 10 natural disasters that have taken place in Canada
according Environment Canada.
- Conservation Ontario is the name of the organization
that includes all Conservation Authorities. What was the natural disaster
that prompted
the formation of this organization? What is the geographic area and
mandate of any Conservation Authority? How many are there in Ontario? www.trca.on.ca and www.conservationontario.org
The Institute for Catastrophic Loss Reduction was founded to provide
a forum for insurers and others to work together to reduce
the loss of life and property caused by severe weather and earthquakes.
The results of their assessment studies led the insurance industry to
conclude that a number of factors contributed to the rising disaster
losses. These include climate change, aging infrastructure, and an increase
in people and property at risk. See www.ICLR.org
Climate Change as a Factor
The climate projections for the end of this century (2100) are greater
than 20oC for the Canadian Arctic and from 3 to 10oC for the rest of the
country. (See IPCC QUICK TIME.) Climate change is projected to increase
weather extremes, both in frequency and in severity. For example, extremes
in weather such as heavy precipitation in short periods of time increase
the vulnerability of our infrastructure to flooding. Retrofitting existing
structures, and building for lower extremes to withstand the increase
in weather loads, for example, snow load, ice loads or flooding, should be done
with updated designs which consider the impacts and projections of climate
change. Considering the risk of return of known extreme weather events
should be part of planning for infrastructure renewal or expansion.
The risk of a return of the 1998 ice storms to areas in Ontario is shown
below.

ACTIVITY 3
- What kind of map is this based on? What does the line with the number
30 represent?
- State two geographic /meterological reasons why the area of highest
risk is located between Shelburne and Fergus? Check this against the
eastern Ontario data provided by www.mnr.on.ca around
Kemptville. What could be the reason for the severity of the 1998 ice
storm there?
- What was the most significant
change in people's lives
during this ice storm?
ACTIVITY 4 Research
- Answer questions 3 and 4 with respect to the flood in Peterborough,
Ontario, 2004.
- What other Ontario cities might be susceptible to such flooding?
To understand how a small change in temperature can be responsible for
more temperature extremes, find the bell curves for the changes in frequency of extreme weather.
See Section 2.4 Graphs and Analysis in Section 2 Overarching Concepts.
An increase of 1.6oC in the mean air temperature would cause the change
in frequency of extreme maxmium temperatures to be much greater. Extremely
warm summers at this location, normally expected every 25 years, would
have a return period of only one year in the warmer climate. Small temperature
changes can thus result in significant changes in the extremes.
Aging Infrastructure as a Factor
In the past few decades Ontario, as the rest of Canada, has spent less
of its GDP on infrastructure. The age of existing infrastructure is at
least an average of 25 years. Upgrading and/or designing new infrastructure
means building more than roads, bridges or mass transit. It includes
sewage and water treatment, delivery systems, and public buildings.
ACTIVITY 5 Research
- How old is the sewer system, the water treatment and delivery system,
the power system or the public buildings, such as schools, in your
local municipality?
- What emergency measures are in place for natural disasters in this
municipality?
- Where are the plans for these emergency measures? Are they available
to the public?
Societal factors
The size and wealth of human populations are also factors in the increasing
cost of natural catastrophic losses. The size and density of the population,
especially in urban areas, is reflected in the cost of these losses. The urbanization
of the province, indeed of Canada, is also reflected in the number of
motor vehicles registered.
ACTIVITY 6 Research
- What is the relationship between increase in the urban population
and the number of motor vehicles registered in Ontario from 1901 to
1999?
- Check the development of Ontario roads in Section 5.2.2c. How many
kilometers of roads are there in Ontario in 2005?
- Carry out the same research for the number of kilometers of railroad
in the Ontario
Responses of society to extremes of weather and to climate change will
have to take into account the increase in vulnerabililty and value of
resulting losses. It is projected by the insurers that the cost of losses
is likely to continue to increase even if the changing climate does not
to bring an increase in weather extremes. Climate change simply increases
the risk of damage.
The insurance industry emphasizes the need to develop and plan strategies
of mitigation and adaptation to respond to the challenge of reducing
risk or vulnerability to these losses. More loss reduction research is
needed.
