This study addresses three questions: to what extent lobbying efforts under
taken by associations vary across different types of associations; what are
the different lobbying instruments used by Canadian associations; what fac
tors explain the intensity of the lobbying efforts deployed by the Canadian
associations? These questions are dealt with through a sample of 438 assoc
iations operating in 12 different policy domains and at three possible leve
ls of government (Canadian, provincial and municipal). The results show tha
t leisure associations deploy less intense efforts in lobbying than public
and private goods associations. Likewise, public and private goods associat
ions do not appear to differ significantly with respect to efforts deployed
in lobbying. Furthermore, the results show that the lobbying instruments u
sed by associations differ across the different types of associations. Fina
lly, the results indicate that competition between associations, participat
ion in coalitions of associations and the number of policy domains in which
associations have intense interests are significantly related to efforts d
eployed in lobbying by associations in many different policy domains. Howev
er, the variables related to the material resources of the associations hav
e been shown to exert no significant impact on the lobbying efforts of Cana
dian associations.
