The 1993 Canadian General Election was an extraordinary one. The elect
ion featured the collapse of a once stable two-party-plus party system
and the emergence of a less stable one-party dominant system. The gov
erning Progressive Conservative party went down to the most crushing d
efeat of any governing party in Canadian electoral history, and two ne
w parties displaced two old ones. This article places this dramatic fr
acturing in the context of Canadian post-war electoral history. It dra
ws upon well-known perspectives on spatial theory to illustrate how on
e new party, the Reform Party, captured the political right. It then d
emonstrates how the strategic interests of both of the two new parties
, Reform and the independent Bloc Quebecois, combined to undermine the
integrative role that Canadian political parties have traditionally s
erved. We argue that the present one-party dominant system is unstable
and, after speculating about how the Canadian party system may return
to a stable alignment, we consider the broader implications of the el
ection outcome.
