Conference on Security and Co-operation in Europe (CSCE): Final Act of Helsinki | The Brian Mulroney Institute of Government

The Helsinki Final Act was signed on August 1st, 1975, by 35 nations including Canada, the United States, and every European country (aside from Albania).
The Act represents the concluding document of the Conference on Security and Co-operation in Europe (CSCE), which started at Helsinki in 1973, continued in Geneva, and concluded back in Helsinki in 1975.
Canada participated in the negotiations that led up to the Helsinki Accords with the Society Union
The Helsinki Accords were a vital part of the foreign policy element of Canada's rights revolution, which, among several things, committed the signatories to a set of human rights principles.
These international commitments provided an opportunity for parliamentarians to engage in foreign affairs that related to human rights by drawing upon the language within the Accords to introduce resolutions dealing with issues like family reunification, free movement of people, and religious freedoms (among other things) into Parliament.
These accords, alongside other international conferences on human rights issues, gave Members of Parliament valuable expertise to bring human rights knowledge into Parliament and to pressure the federal government into further instilling human rights into foreign policy decisions.
