TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

依勒特

During Canada’s “Housing Boom”, which ran roughly
from 2002 to 2008, unsustainable price increases drove
unsustainable levels of building. Our view is that house
& r! U! g& w0 g" Jprices exceeded the value of housing that was justified by
fundamentals by approximately 9% nationwide. This

that exceeded its fundamental-justified level by approximately
12%, an excess that was exaggerated in the past

By “overpricing” we mean that prices detached from
their fundamentals, as witnessed by a steep erosion of
affordability. The current unwinding of house prices reflects
both a cyclical downturn and a return of house prices

We consider “overbuilding” of two forms: “demanddriven”
where homebuyers buy up too many houses and

there is evidence of both types, we contend that Canada’s

that is now being rapidly reined in.

the construction of too many new homes over the boom
means a deepened slump. This overbuilding will likely weigh
on markets over the next few years. Even as Canada recovers

remain choppy and new residential construction will be

is now undershooting fundamentals and we expect this
to persist over 2009 to 2011. We anticipate that nationwide

To quantify the degree of overpricing and overbuilding,
we first develop an empirical model, based on long-run

province. Affordability is the key concept behind home
values since house prices should track incomes over the
" e! c" k. u, _% ]long-run. Since homebuilders build to meet demand, we
regard housing prices and household formation as the drivers
of residential construction.
To examine the degree of overbuilding, we employ a
“counter-factual,” asking what level of residential construction
would have occurred if housing had been priced

fundamental-justified level by about 12%. Although new
units were being absorbed, homebuyers simply bought too

buyers’ territory. Homebuilding in the Atlantic provinces
has been relatively balanced but, while not plagued by structural
weakness, will be singed by the downturn nonetheless.
Québec shows signs of strain – especially given the
strange accumulation of unabsorbed multiples on l’Île de
Montréal – but recent building has been relatively balanced,

high levels of apartment-style units presently under
construction mean that record numbers of condos will
reach completion during 2009. If absorption rates fall, as

spike severely – particularly in Vancouver. However, while

anticipate that the West Coast will continue to benefit from
inter-provincial and international migration over the coming

will alleviate some of the pressure from overbuilding.
