Alberta, Canada's oil-producing province, is holding a vote that could define its relationship with the rest of the country. Electors have been asked whether they want to remain in Canada or take a step toward holding another referendum on breaking away. The question follows an earlier referendum that ended with neither side of the debate satisfied. Separatists and supporters of staying in the federation both walked away unhappy from that outcome. The new vote keeps open the possibility that a renewed secession push could gain ground depending on how Albertans respond. The province's oil wealth gives its complaints about its place in the federation national consequence. Whatever the ballot produces, the result is expected to reverberate in the argument between Alberta and Ottawa.
