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
prices exceeded the value of housing that was justified by
fundamentals by approximately 9% nationwide. This

that exceeded its fundamental-justified level by approximately
12%, an excess that was exaggerated in the past

; U! ?' u; J! {* W* GBy “overpricing” we mean that prices detached from
their fundamentals, as witnessed by a steep erosion of
affordability. The current unwinding of house prices reflects

We consider “overbuilding” of two forms: “demanddriven”
" `+ U% h6 [/ T& wwhere homebuyers buy up too many houses and
that this demand cannot be sustained; and “supply-driven”
0 a' J0 c9 M1 vwhere builders accumulate excessive inventories. Although
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.
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

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.

already witnessing surges in their unsold new homes at the
