Yes, market prices certainly play a very important role. In some cities, the market makes it very difficult to find affordable housing. However, it is also a matter of the concentration of people of indigenous origin in some cities. Winnipeg and Vancouver are the two cities with the highest number of people of indigenous origin in need of affordable and adequate housing. In Winnipeg, this is not necessarily because of the high cost of housing, but rather because of the size of the population. In Vancouver, it is clearly because of the extremely high cost of housing.
On the other hand, in some areas where the cost of housing is historically somewhat lower, the need is somewhat less acute. The proportion of people of indigenous origin living in unaffordable or inadequate housing is indeed lower.
It is therefore clear that market prices have a significant impact on housing.
