TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

During Canada’s “Housing Boom”, which ran roughly
; Y( [4 e7 {- f2 Y. {from 2002 to 2008, unsustainable price increases drove
unsustainable levels of building. Our view is that house
2 ^8 Z" O) e: z3 s6 ]prices exceeded the value of housing that was justified by
fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction

# P3 ~2 t2 ~8 |/ X; J# [- G12%, an excess that was exaggerated in the past
three years.
- n1 w$ `' T% gBy “overpricing” we mean that prices detached from
their fundamentals, as witnessed by a steep erosion of

$ e. o; P3 u7 Z% `both a cyclical downturn and a return of house prices
to fundamentally justified levels.
) }& [/ y' ~+ i9 F$ Q1 q5 pWe 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
$ h% U8 f# [- }( S; ]- }there is evidence of both types, we contend that Canada’s
“overbuilding” was mainly of the first type, where
homebuyers pushed homebuilding to an unsustainable pitch
that is now being rapidly reined in.
4 a3 m6 K/ p; U7 fWhile most markets won’t face U.S.-style overhangs,
( I( U9 B: t2 Q8 J# P* qthe construction of too many new homes over the boom
means a deepened slump. This overbuilding will likely weigh
+ Y3 D$ E7 W/ s1 h. x! Ion markets over the next few years. Even as Canada recovers
7 e% f; |0 ~, h. G2 Rfrom 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
to persist over 2009 to 2011. We anticipate that nationwide
residential construction will fall further to around
125,000 starts over 2009 with a trough around 115,000 units
in the fourth quarter.
& Y# u3 Z& e6 {7 o/ g* b6 FTo quantify the degree of overpricing and overbuilding,
we first develop an empirical model, based on long-run
; E7 e  ]; w6 T4 Hfundamentals of house prices and housing starts in each

! f' L( J1 o. C: Jlong-run. Since homebuilders build to meet demand, we
  W( _! U; |, Fregard 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
9 O8 X7 l& p) _0 nfundamental-justified level by about 12%. Although new
units were being absorbed, homebuyers simply bought too
many houses at prices that exceeded fundamentals.
Regionally, we see the greatest strains on the Prairies,
where housing demand will further contract under waning
population inflows. Saskatoon, Calgary and Edmonton are
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
( n- `+ ~0 H$ c$ C" Zhas been relatively balanced but, while not plagued by structural
weakness, will be singed by the downturn nonetheless.
* k7 n5 N' R# V( s0 a1 K5 v: jQuébec shows signs of strain – especially given the
strange accumulation of unabsorbed multiples on l’Île de
Montréal – but recent building has been relatively balanced,
given the province’s history of under-building and low ownership

cyclical downturn, the degree of structural weakness appears

condo market. Both in Toronto and Vancouver, historically

cyclical factors would indicate, condo inventories could
spike severely – particularly in Vancouver. However, while
residential construction in B.C. will definitely droop, we
anticipate that the West Coast will continue to benefit from
inter-provincial and international migration over the coming
