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

4 L: D: i5 u3 _+ }) ?overpricing compelled a level of residential construction
that exceeded its fundamental-justified level by approximately
12%, an excess that was exaggerated in the past
three years.
# L* z& ^: q3 j. K) U5 hBy “overpricing” we mean that prices detached from
their fundamentals, as witnessed by a steep erosion of

to fundamentally justified levels.
! t# i% ], H8 _$ e; e) V9 ZWe consider “overbuilding” of two forms: “demanddriven”
where homebuyers buy up too many houses and
that this demand cannot be sustained; and “supply-driven”
where builders accumulate excessive inventories. Although
there is evidence of both types, we contend that Canada’s
“overbuilding” was mainly of the first type, where

While most markets won’t face U.S.-style overhangs,
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
from the cyclical downturn, house price growth will
remain choppy and new residential construction will be

to persist over 2009 to 2011. We anticipate that nationwide

5 V- P" r7 l4 u; `we first develop an empirical model, based on long-run
fundamentals of house prices and housing starts in each

values since house prices should track incomes over the
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
optimally. We find that actual homebuilding exceeded this
fundamental-justified level by about 12%. Although new

many houses at prices that exceeded fundamentals.
Regionally, we see the greatest strains on the Prairies,

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

given the province’s history of under-building and low ownership

reach completion during 2009. If absorption rates fall, as
cyclical factors would indicate, condo inventories could
spike severely – particularly in Vancouver. However, while
