And, "the higher number of multigenerational households may also be related to housing needs and the high cost of living in some regions of the country", said the report.
Those are the findings of the latest release of data from the 2016 census which looks at the number of people who share the same roof, the types of families Canadians are choosing and the range of languages they can speak.
The numbers show that fewer and fewer Canadians are living in traditional households - made up of a mom, dad and kids - and more people are living alone, as part of a couple without children, or as part of a multigenerational family.
Canadians' lives at home have evolved since Confederation, when large rural families consisting of a married couple and several children were common.
Among the Atlantic provinces, Nova Scotia has the highest percentage of one-person households at 29.5 per cent, higher than the national average. The agency suggests greater economic independence, an aging population, and a higher life-expectancy account for the increase in more seniors than ever living alone. The evolving living arrangements and families of Canadians can also have consequences, for example on the housing market, on caregiving and care receiving and on intergenerational relationships.
The number of people separated was also higher in New Brunswick and Nova Scotia a year ago, but down in Newfoundland and Labrador and P.E.I.
It's also the first time people living alone is the most common household, surpassing couples with children.
The share of adult children living with a parent was 34.7 percent previous year, up from 33.3 percent in 2011 and 33.1 percent in 2006, the report showed.
Still, one-person households were the most common type of household in the country a year ago for the first time in the country's history. (No, they're not thrilled about it, either.) The percentage of young people with families of their own has dropped to 42 per cent from 49.
For the first time in the country's history, the number of one-person households has surpassed all other types of living situation.
On the martial status front, Statistics Canada says while the majority of people get married, common law unions continue to increase.
Some 228,770 people reported speaking an Indigenous language at home, while only 213,230 reporting having an Indigenous mother tongue - evidence that more people are adopting them as a second language. Those living with children fell to 25.5 per cent from 32.9 per cent in 2001. As a result, the percentage of couples living with at least one child fell from 56.7 percent in 2001 to 51.1 percent in 2016. A vast 255,335 residents over the age of 15 are single (or at least not married to/living with their partner). The number of overall English speakers was up from 2011, while the number of French speakers declined across Canada and in Quebec. We have far more couples in households without kids (53,540) than with (37,410).
However, in 2011, the proportion of people that age living with their parents was 12.5, pointing to many young adults moving back in after a period spent outside the family home.
In addition, there has never been as little of couples living without children across the country, highlights Statistics Canada. But, between 2006 and 2016, that increased by 60.7 per cent, compared with an increase of just 9.6 per cent for heterosexual unions.
It points to the aging population for this shift.
Although there were slightly more male than female same-sex couples previous year, a slightly higher proportion of the female couples were married.
