Nope but my in-laws are. My family makes a regular trip up to Toronto about twice a year.
The common law relationships in Canada came up when I mentioned some of my stepfamily here in the states. One pair had four kids together (never married) and then the lady skipped off and is now having another kid with the in-law of the first baby daddy. It's a regular Maury Povich show.
Thankfully, they're not blood relation.
I probably have more friends on the other side of the border than this side - most of them small town, rural type folk. I'll have to remember to ask them what they think about that sort of thing when I see them next. They'll probably say it's a city thing. :chuckle:
