homeless are a symptom of many things. healthcare. lack of rentals. lack of employment. lack of social services.
but what is known is that there has been a huge increase in the rate of population growth in Canada in the last several years, along with a decrease in natural population increases (lowering birth rate) and a massive increase in immigration. While housing is an issue, there were never enough spare beds for the increase, and never could be, in the time frame they were required.
