TD Bank:OVERPRICED AND OVERBUILT: CANADIAN HOUSING

During Canada’s “Housing Boom”, which ran roughly
5 ^! M* a' G! _8 lfrom 2002 to 2008, unsustainable price increases drove
4 Q5 W& v7 y* u( H) sunsustainable levels of building. Our view is that house
! G* L& V* v5 v+ j7 [( f6 \prices exceeded the value of housing that was justified by
: G; h( V: N. V" _fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction

12%, an excess that was exaggerated in the past

By “overpricing” we mean that prices detached from

* W5 P8 J  m; ~6 Q6 r! Y) Qwhere 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

homebuyers pushed homebuilding to an unsustainable pitch

on markets over the next few years. Even as Canada recovers
8 b7 }, U( K2 e" G9 Ufrom 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.
To quantify the degree of overpricing and overbuilding,
we first develop an empirical model, based on long-run
' E# L( I- G% Y6 Qfundamentals of house prices and housing starts in each
) O) \$ Z1 K% l( O; Aprovince. Affordability is the key concept behind home
values since house prices should track incomes over the
" K7 m/ j0 A6 S; t* ulong-run. Since homebuilders build to meet demand, we
regard housing prices and household formation as the drivers
of residential construction.
  g' I0 h( e. _5 t5 e% NTo examine the degree of overbuilding, we employ a

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

where housing demand will further contract under waning
& K- F7 I* E7 g5 Y* B0 W# [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
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
# ~% {+ I* x- I* l$ y' Pstrange 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
high levels of apartment-style units presently under
construction mean that record numbers of condos will

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

will alleviate some of the pressure from overbuilding.
