TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

依勒特

During Canada’s “Housing Boom”, which ran roughly
" C( S4 T7 U- G3 H0 [from 2002 to 2008, unsustainable price increases drove
unsustainable levels of building. Our view is that house
prices exceeded the value of housing that was justified by
fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction
2 H7 {5 P* J  Nthat exceeded its fundamental-justified level by approximately
0 U1 E& p( C7 T2 U& Y$ K2 S; T12%, an excess that was exaggerated in the past
three years.

where homebuyers buy up too many houses and

where builders accumulate excessive inventories. Although
there is evidence of both types, we contend that Canada’s

homebuyers pushed homebuilding to an unsustainable pitch

While most markets won’t face U.S.-style overhangs,
; K4 q6 C" L% ?7 U: Tthe 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
dampened, owing to this structural weakness. Construction
is now undershooting fundamentals and we expect this

residential construction will fall further to around

in the fourth quarter.
To quantify the degree of overpricing and overbuilding,

fundamentals of house prices and housing starts in each

7 q$ I) B) |! h  ^) _9 |$ yregard 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
' u, l8 `0 ?1 V) o# Poptimally. We find that actual homebuilding exceeded this

already witnessing surges in their unsold new homes at the
very time that the resale market has swung into strong
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,
