Statistics Canada has released a detailed analysis of the composition of families and living arrangements in the country according to the 2021 census.
57% of adults in Canada were part of a couple (married or common law) and this is similar to the proportion exactly 100 years earlier, in 1921 (58%).
Among couples, marriage remains the predominant type of union as more than three-quarters (77%) of couples were married, with the remaining 23% living common law.
As per the report, 4.4 million people aged 15 and above lived alone in 2021. Canada has the second lowest proportion of one-person households at 3 in 10 households (29.3%) among the G7. Only the United States had a slightly smaller share (28.5% in 2021).
In 2021, most (98.5%) of Canada’s 8.6 million couples were different-gender couples, meaning they included one woman and one man and 1.5% of couples (127,640) were either same-gender couples, transgender couples or non-binary couples.
Same-gender couples, that is, a couple in which there were either two women or two men, and both members were cisgender, represented 1.1% of all couples.
Transgender or non-binary couples, in which at least one member was transgender or non-binary, represented about 1 in every 250 couples (0.4%).

Highlights – Marriage & Living Alone:
- Most adults have a spouse or partner.
- In 2021, more than three-quarters (77%) of couples were married, with the remaining 23% living common law.
- Younger adults are less likely to be living as part of a couple—as alternatives like living alone, with roommates or with parents have become more common.
- From 1981 to 2021, the number of common-law couples increased by 447%, this is a much faster growth than that of married couples over the same period (+26%).
- The prevalence of common-law unions in Nunavut (52%), Quebec (43%) and the Northwest Territories (36%) are higher than in Sweden, which is the country with the highest rate of common-law unions at the national level (with one-third of couples living common law).
- More couples live common law in rural parts of the country, compared with urban areas. 21% of couples lived common law in Canada’s large urban centres, just below the national average of 23% due to relatively larger populations of immigrant and racialized groups where marriage is more prevalent.

Households composed of roommates— two or more people living together and not part of a census family—are the fastest-growing household type ( increased by 54% from 2001) in Canada But this still represented a small share of all of Canada’s households in 2021 (4%).
