On November 22, 2010, Chief Justice Robert Bauman began hearing arguments on the constitutionality of Canada’s existing polygamy laws in British Columbia’s Supreme Court. Section 293 in the criminal code currently outlaws polygamy, or “any kind of conjugal union with more than one person at the same time.” 
While the case raises passions both for and against polygamy, there is certainly a third segment of Canadian society: Those who don’t understand why it matters. A columnist in the Vancouver Sun, Pete McMartin wrote that if we are going to criticize polygamy, perhaps we should also look at monogamy, since abuse occurs in that context as well. A letter writer wrote in agreement, saying, “Who gives a whit about polygamy as practiced by adults and why should the argument about marital arrangements and/or religion distract from the real potential criminal or social issues?” 
While it is important that polygamy remain illegal, it is equally important that Canadians understand why. What the nation needs, then, is to hear a thorough defence of why marriage matters in Canadian society. Marriage has substantial public functions, and as a result public discussion of the purpose of marriage is very much warranted.
Marriage is the bulwark of our economy. Without strong and lasting marriages, we cannot count on the ongoing strength of our economy. This is a truism we have forgotten, such that today, it is a statement that needs defending. Recently, Dainius Kreivys, the Lithuanian Minister of the Economy, made this very point publicly. “If traditional family values were stronger in our society, we would have a much stronger economy, not to mention a more mature society... Nobody can deny that successful families more often produce responsible citizens who later also become outstanding professionals. Economically, that means better qualified specialists, people who create added value in the economy, people who support themselves, create jobs, maintain a family and pay taxes; people who do not live off welfare benefits.” 
Intact marriages are likewise a social safety net. Single parent families are more likely to be dependent on welfare, and are far more likely to fall below the Low Income Cut-Off (LICO). 
Marriage is inclusive. It allows men to engage in the creation of a family, and be affiliated with any resulting children. Research shows married men are more engaged in civic society, less likely to be engaged in criminal activity, drugs or gangs, and more likely to be healthy. 
Marriage (the two-person, male/female variety—we have no studies as of yet on same-sex marriage) is a positive indicator for improved health, longer life and decreased depression. 
Marriage creates a healthy foundation for new families. Cohabitation is on the rise, but this should be correctly identified as an ominous trend because these relationships are far more likely to break up than marriage. Research shows living together does not offer the same stability as marriage. 
This evidence shows that marriage is not exclusively a personal relationship. If it were, it would be irrelevant to public policy. Some scholars go even further than that, stating that without a public dimension, marriage falls from irrelevance into non-existence. “If marriage does not have a valid, comprehensive public dimension, then marriage for all intents and purposes does not exist,” writes David Blankenhorn, author of The Future of Marriage and a non-religious, nonpartisan marriage scholar. 
Blankenhorn defines marriage this way: “In all or nearly all human societies, marriage is socially approved sexual intercourse between a woman and a man, conceived both as a personal relationship and as an institution, primarily such that any children resulting from the union are— and are understood by the society to be—emotionally, morally, practically, and legally affiliated with both of the parents.” During Canada’s same-sex marriage debate, an exclusive definition of marriage was deemed to be judgmental. But in order for marriage to survive and thrive, it must be exclusive. Marriage cannot logically include every relationship form. Without exclusivity, whether defined by number, gender or preferably both, there is no meaning left to marriage.
In our politically correct world, it is unpopular to discuss the idea that heterosexual, two-person marriage is unique. The reality is that children fare best when raised by their married, biological parents and contrary to what the mainstream media would lead you to believe, we don’t have reliable research on whether same-sex parenting offers the same.  We do have some evidence of harm resulting from polygamy, but given that harm or the lack thereof has not been a factor in deciding constitutionality in the past, it remains to be seen what the courts will decide.
Certainly it is not wise to shrug and assume that whatever the outcome, it doesn’t matter. For one, polygamy is not limited to Bountiful, British Columbia, given reports of polygamous Muslim families living in Toronto, collecting multiple benefits.  Arguably, this court reference on polygamy could have much broader implications than those associated with same-sex marriage.
The bottom line for family advocates is that we should welcome each and every opportunity to discuss the research on how and why family form matters. For it is this information that will give Canadians the ability to decide for themselves what sort of relationships will enhance their own lives and strengthen our culture, our communities and our economy at the same time.
