Good points being raised, great discussion so far.

There was an attempt to get SSM banned, which failed and Stephan Harper promised to not raise the issue again.

However that would imply that the Federal Government does have the ability legislate a ban on polygamy.

And it seems like a common view in this thread is that polygamy as a concept between consenting adults is fine, but in practice this isn't what occurs. Aren't there many laws in place that, if you were to think about them, are exactly in this same class? Speeding - if you were the only car that could possible be on the road, and you would personally pay for medical care/accident costs (i.e. no societal costs), would anyone really care? If you buy your own property and build your own road you can go as fast as you want, but if you want to go on public roads you need to abide by the public laws regardless of if there is another car on the road. If you want to shack up with as many of the opposite sex as you want, you are free to do so. But as soon as you look for government sanctioning you are now "driving on a public road" and must abide withint the rules of the road.

So I think government is fully within its rights to prohibit this arrangement.
