If we use the international definition of metro areas (the FUA), which is now used by the Brazilian statistical office:
At the 2022 Brazilian census:
- Sao Paulo metro area: 20,673,280
- Rio de Janeiro metro area: 11,760,550
So Rio is only 57% of Sao Paulo.
For Canada, in 2021, also the FUAs:
- Toronto: 7,236,120
- Montréal: 4,575,140
So Montréal is 63% of Toronto. The gap is not as large as between Sao Paulo and Rio (especially economy wise), but it is larger than between Madrid and Barcelona (Barcelona FUA is at 77% of Madrid FUA's population).
