Yes, I do think specific rules need to be adopted respecting expenditures. That said, there is no question that Canadians do love Quebeckers. And why not? I'm from Ontario. Ontario was carved out of a part of Quebec. At one time, the two provinces were like sisters. When an issue is so deeply linked to the future of the country and Canadians' sense of belonging to one country, it affects everyone, from coast to coast. Therefore, I can understand why, under the circumstances, Canadians living outside Quebec felt compelled to travel to Montreal or other communities.
Nevertheless, I do think that some rules should apply to the referendum process.
