text_A: The House of Commons currently has 338 members elected in single-member districts in a plurality voting system (first past the post), meaning that members must attain only a plurality (the most votes of any candidate), which is distinct from having to get a majority (50 percent plus one). The electoral districts are also known as ridings.

YES.
