In Vancouver the major share of the responsibility falls upon the BC NDP junior varsity team Vision(less) Vancouver led by former NDP MLA Gregor Robertson (aka Mayor Moonbeam).

Moonbeam ran several elections on the promise the he would end homelessness in Vancouver by 2015 and that he was the only politician who could get a handle on the DTES drug problems.

Per the CBC:

"The City of Vancouver's most recent homeless count shows the highest number of people without a home in 10 years — despite the governing municipal party's promise to end street homelessness by 2015."

Homelessness was a major part of Moonbeam's Vision(less) Vancouver campaign when he ran for his position in 2008. At the time, he promised there would be no homeless people on city streets by the end of 2015.
