U.S. constitution > Canada's constitution. Lawsuit over this is harder to win in Canada.

Voting is an American principle and a basic democratic right that should be protected, promoted, and practiced, which is why many people are surprised to learn that the U.S. Constitution provides no explicit right to vote. This leaves voting rights vulnerable to the whims of politicians, and some citizens with fewer rights than others.
More than a decade ago, FairVote became the leading institutional voice calling for the establishment of an explicit individual right to vote in the U.S. Constitution. We believe that a grassroots movement to establish such an amendment would go a long way in ending the "voting wars" that plague us today. FairVote continues to serve as a trusted resource in support of activists, organizations, and elected officials working toward a right to vote amendment. Through our Promote Our Vote project, we work to build widespread support for a right to vote amendment, while advocating for pro-suffrage innovations at the local level.

Eligibility to vote in the United States is governed by the United States Constitution and by federal and state laws. Several constitutional amendments (the Fifteenth, Nineteenth, and Twenty-sixth specifically) require that voting rights of U.S. citizens cannot be abridged on account of race, color, previous condition of servitude, sex, or age (18 and older); the constitution as originally written did not establish any such rights during 1787–1870, except that if a state permitted a person to vote for the "most numerous branch" of its state legislature, it was required to permit that person to vote in elections for members of the United States House of Representatives.[1] In the absence of a specific federal law or constitutional provision, each state is given considerable discretion to establish qualifications for suffrage and candidacy within its own respective jurisdiction; in addition, states and lower level jurisdictions establish election systems, such as at-large or single member district elections for county councils or school boards. Beyond qualifications for suffrage, rules and regulations concerning voting (such as the poll tax) have been contested since the advent of Jim Crow laws and related provisions that indirectly disenfranchised racial minorities.
A historic turning point was the 1964 Supreme Court case Reynolds v. Sims that ruled both houses of all state legislatures had to be based on electoral districts that were approximately equal in population size, under the "one man, one vote" principle.[2][3][4] The Warren Court's decisions on two previous landmark cases—Baker v. Carr (1962) and Wesberry v. Sanders (1964)—also played a fundamental role in establishing the nationwide "one man, one vote" electoral system.[5][6] Since the Voting Rights Act of 1965, the Twenty-fourth Amendment, and related laws, voting rights have been legally considered an issue related to election systems. In 1972, the Burger Court ruled that state legislatures had to redistrict every ten years based on census results; at that point, many had not redistricted for decades, often leading to a rural bias.
