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
! `0 y. E8 S# @7 ~unsustainable levels of building. Our view is that house
prices exceeded the value of housing that was justified by
# T4 r$ y9 C! _: m& ]fundamentals by approximately 9% nationwide. This
overpricing compelled a level of residential construction
/ @. @& p4 P3 Ithat exceeded its fundamental-justified level by approximately
4 h0 a( l) r# ^2 v7 _' U; L12%, 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 k2 Q& y. p0 D/ c6 |6 FWe consider “overbuilding” of two forms: “demanddriven”
2 M, Y' F1 F8 s+ jwhere 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
“overbuilding” was mainly of the first type, where

that is now being rapidly reined in.
While most markets won’t face U.S.-style overhangs,
* q1 a: P6 ~+ {/ E" h: }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
remain choppy and new residential construction will be
dampened, owing to this structural weakness. Construction
is now undershooting fundamentals and we expect this

condo market. Both in Toronto and Vancouver, historically
high levels of apartment-style units presently under
