Thank you for the question.
The names of electoral districts are determined by the independent electoral commissions at each decennial exercise. During that process, members can propose names and put forward objections, but ultimately those decisions are made by the independent commissions.
However, members of Parliament can, between those decennial exercises, propose name changes to the ridings for Parliament's approval. In previous decennial exercises, that has been the case, whether through government bills or private members' bills. In 2014 and, before that, in 2004, there have been bills that have changed the names of ridings. That is within the purview of members of Parliament to propose and for Parliament to approve.
