Proponents of fourplexes, which include the Canadian government, hope they will spread out across the country. They want them to provide the “missing-middle” between large apartment buildings and single residency houses.
It comes as fourplexes made headlines this year in Canada after Prime Minister Justin Trudeau announced that the federal government would be making $CAN 6bn ($4.4bn; £3.4bn) in new money available to help provinces tackle the national housing crisis – a lack of affordable properties.
Federal Housing Minister Sean Fraser has required allowing fourplexes as a condition for municipalities to collect their share of this federal housing money.
This has been welcomed by some provinces, such as British Columbia (BC). The BC government has passed legislation to require fourplexes, and even five and sixplexes, to be permitted in any city with a population of more than 5,000.
