Final answer:
The Canadian legislation beaded by Nadia Myre to make a political statement is not specified in the data provided. Her work typically addresses themes of indigenous rights and women's suffrage, drawing attention to political participation and representation in Canada.
Step-by-step explanation:
The piece of Canadian legislation that artist Nadia Myre beaded to make a political statement is not explicitly mentioned in the provided references. However, given the references to self-government for the Métis peoples, the rights of women such as the Alberta Military Representation Act, which allowed nurses like Roberta MacAdams to vote and be elected, and the famous Supreme Court case that recognized women as 'persons' under the British North America Act, it is likely that Nadia Myre's work comments on similar themes of indigenous rights and women's suffrage to engage in a critical dialogue about political participation and representation in Canada.
An examination of these legislative milestones and the historical context may point towards pieces like the Indian Act, which has had significant implications for indigenous peoples in Canada and has been the subject of artistic critique including that of Nadia Myre's beadwork.
