MULRONEY: On March 26 [1985] the United States invited Canada and other friendly countries to participate directly in research under the Strategic Defense Initiative. After careful and detailed consideration the government of Canada has concluded that Canada's own policies and priorities do not warrant a government to government effort in support of SDI research. Although Canada does not intend to participate on a government to government basis on the SDI research program, private companies and institutions interested in participating in the program will continue to be free to do so.
