Following the world oil price shock of the early 1970s, departments an
d agencies of the governments of Canada and of a number of provinces s
pent in excess of $1 billion on programs aimed at encouraging natural
gas utilities to expand their distribution systems. We describe these
programs and the associated public expenditures in each province, and
examine their effects on the construction activities of utilities. Usi
ng an annual series on access to gas service that we construct for eac
h province for the period 1961 to 1990, we also examine the effects of
these programs on changes in access and on how such access has evolve
d relative to changes in the pipeline distribution system.
