OTTAWA, Ont. – Canadian families don’t look like they used to.

Statistics Canada has just released a new round of data from the 2011 census.

It finds the share of married couples is on the decline. There are nearly 9.4-million families in Canada with 67 per cent of them made up of married couples.

“I think it’s related to the fact that we saw a large increase in common law couples, so people are shifting from married to common law. It’s not a new trend, we’ve seen this coming for years,” Laurent Martel with Statistics Canada said.

According to the data, the number of common-law couples rose by 13.9 per cent between 2006 and 2011, more than four times the growth of married couples.

And for the first time, the number of common-law families surpassed the number of single-parent households.

The province with the highest number of common-law relationships is Quebec with 31.5 per cent, followed closely by the Northwest Territories and Yukon.

The number of same-sex couples has increased by by 42.4 per cent and are mostly living in Toronto, Montreal and Vancouver.

The number of same-sex couples who have gotten married has tripled since it became legal in 2005.

Even still, the majority of them were choosing common-law arrangements.

The census also charts the growing number of empty-nesters.

The number of couples with children at home continued to fall from 44.5 per cent in 2006 to 39.2 per cent in the latest survey.

“Probably largely to population aging, the baby boomers have their kids in the 60s, 70s and 80s, and now the kids are leaving,” Martel said.

And for the first time, the census counted stepfamilies, registering 464-thousand 335 of them — or 12.6 per cent of couples with children.
