Our principal sources of Canadian data are national cross-sectional and panel surveys conducted in 1983, 1984, and immediately before and after the 1988 federal election. The 1983 survey also contains a panel component composed of persons interviewed in the 1979 and 1980 national election surveys. The 1983, 1984, and 1988 surveys are the centerpieces of two research projects: “Sources, Distribution and Consequences of Political Support in Canada” and “Support for Democratic Polities: The Case of Canada” (co-principal investigators Harold D. Clarke and Allan Kornberg). The studies were funded by the National Science Foundation (grants SES 831-1077 and SES 882-1628). Fieldwork for the surveys was conducted by Canadian Facts Ltd., Toronto, Ontario under the supervision of Canadian Facts’ Senior Project Director, Mary Auvinen. Additional Canadian data were gathered in national cross-sectional surveys conducted in 1985, 1986, 1987, and 1989, with the fieldwork for these studies being conducted by Canadian Facts Ltd. as part of their monthly “Monitor” survey. Funding for these latter studies was provided by research grants from the Canadian Embassy, Washington, D. C, the Canadian Studies Center, Duke University, the International Political Economy Program, Duke University, and the Duke University Research Council and Provosts' Funds. All of these survey data and related technical information are available from the authors upon request.

We also employed Canadian data gathered in the 1974, 1979, and 1980 national election and panel surveys and two surveys carried out at the time of the Quebec sovereignty-association referendum. The principal investigators for the election studies were Harold D. Clarke, Jane Jenson, Lawrence LeDuc, and Jon Pammett, using research funds provided by the Canada Council and the Social Sciences and Humanities Research Council of Canada. One of the referendum surveys was conducted as part of a project “The Quebec Referendum, the Media, and the Maintenance of the National Integrity of Canada” (principal investigators: Allan Kornberg and Joel Smith) funded by the National Science Foundation (grants SOC- 7915420). A second was the “Quebec Referendum Study” carried out by Clarke, Jenson, Leduc, and Pammett in conjunction with their 1974-80 national election surveys. The latter research was supported by the Social Sciences and Humanities Research Council of Canada. The 1974 election study is described in Clarke et al. (1979:397-400), and information regarding the other surveys can be obtained from the principal investigators.
