TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

During Canada’s “Housing Boom”, which ran roughly
' ~  @; L2 p4 g/ j0 pfrom 2002 to 2008, unsustainable price increases drove
+ G+ @8 o0 ^% }$ G# B- g8 I" [+ t' eunsustainable levels of building. Our view is that house
prices exceeded the value of housing that was justified by
% a( f- b& w9 P$ g1 m( v7 L0 \fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction
% I  |! s* t3 i) c7 X/ lthat exceeded its fundamental-justified level by approximately
12%, an excess that was exaggerated in the past
three years.
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
8 U/ J6 f4 l4 ?) ?9 Hboth a cyclical downturn and a return of house prices
to fundamentally justified levels.
We consider “overbuilding” of two forms: “demanddriven”
where homebuyers buy up too many houses and
4 B) K9 T+ W+ V6 k  k* M; @- ]that this demand cannot be sustained; and “supply-driven”
# r% ]8 e) f: r! P" v! B  kwhere builders accumulate excessive inventories. Although
, T. ^0 j9 M# u: nthere is evidence of both types, we contend that Canada’s
: ]- r/ Q; m( o. S) N' d“overbuilding” was mainly of the first type, where
  [- c, T6 Q7 h: C; d# zhomebuyers pushed homebuilding to an unsustainable pitch
# R8 i4 p4 H. bthat is now being rapidly reined in.
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
# R( b4 A# G; d8 A) B3 r* Wfrom the cyclical downturn, house price growth will
remain choppy and new residential construction will be
dampened, owing to this structural weakness. Construction

to persist over 2009 to 2011. We anticipate that nationwide
" w5 _) ?: D% s- X$ sresidential construction will fall further to around
125,000 starts over 2009 with a trough around 115,000 units
in the fourth quarter.
5 E; V3 o& A2 P9 y# {' F( oTo quantify the degree of overpricing and overbuilding,
& U! J  ]4 y2 O9 _; d$ l& Fwe first develop an empirical model, based on long-run
fundamentals of house prices and housing starts in each
province. Affordability is the key concept behind home
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
5 x( c; L, G. Yof 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
units were being absorbed, homebuyers simply bought too

Regionally, we see the greatest strains on the Prairies,
where housing demand will further contract under waning
; p) D9 B" [4 qpopulation inflows. Saskatoon, Calgary and Edmonton are
" f5 q! v' S/ galready 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
6 o0 e+ N/ w" v& ~6 V( _9 Fweakness, 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,
given the province’s history of under-building and low ownership
rates. While Ontario homebuilding will reel from a
cyclical downturn, the degree of structural weakness appears
" @* F$ F0 f+ ^  Z( ?, climited – with the important exception of the Toronto
. e1 L8 q) N! e+ w8 j! |condo market. Both in Toronto and Vancouver, historically
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
$ R, a( U9 n% f2 Q! vcyclical 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
7 s) ]9 O& F$ {inter-provincial and international migration over the coming

will alleviate some of the pressure from overbuilding.
