When Marie Morrison first started her career in the homelessness sector,ÌýnoÌýoneÌýhad heard ofÌýBy-Name Data or Coordinated Access — twoÌýfundamentalÌýelements now considered essential in the work to end homelessness.Ìý
Housing FirstÌýwasn’tÌýa term yet coined.Ìý
To say theÌýsectorº£½ÇÉçÇøÌýapproach has shiftedÌýsince thenÌýwould be a remarkable understatement.Ìý
“WeÌýcan fairly say MarieÌýhas helpedÌýrevolutionizeÌýCanadaº£½ÇÉçÇø response to homelessness.ÌýWe’veÌýgrownÌýa movementÌýfromÌýwhat sheÌýdevelopedÌýwith BuiltÌýForÌýZero-Canada, and she has set in motion a legacy that is going to continue far beyond her time,â€� said Tim Richter, President and CEO of the Canadian Alliance to End Homelessness (CAEH).Ìý
“Sheº£½ÇÉçÇøÌýjust been this force of nature for so long. She threw her heart and soul into this work, and you can see it,â€�ÌýTimÌýsaid.Ìý
Career started in WaterlooÌý
Marieº£½ÇÉçÇø career in the sector began in 2001. At the time, as the system manager for homelessnessÌýwithÌýthe Region of Waterloo, sheÌýwas responsible forÌýcoordinating federal,ÌýprovincialÌýand local funding to respond to homelessness.Ìý
She built local relationships, mapped existing services, gatheredÌýdataÌýand wrote plans — gradually shifting from a mindset of managing homelessness to ending it.Ìý
“We were overwhelmed and pulled in so many directions. There was not a clear path on how we could support the community to get there. We were very “connected,â€� and thought we were collaborating and coordinating our efforts, but really,Ìýwe were still offering services to people in silos,â€� Marie said.Ìý
That changed in late 2014, when Waterloo became the first community in Canada to implement aÌýConnection and ActionÌýWeek as one of a few pilot communitiesÌýfor theÌýthen-fledgling CAEHº£½ÇÉçÇø 20,000 Homes Campaign.Ìý

Marie Morrison gives a speech about the 20,000 Homes Campaign.
Better than a static Point-in-Time Count, whichÌýcollected data that wasÌýimmediatelyÌýoutdated andÌýdidn’tÌýallow for follow-up, the Region of WaterlooÌýgathered actionable data asking for the consent of people experiencing homelessness to collect their names and information on housing and health needs.Ìý
“This was the beginning of our By-Name Data, a comprehensive, real-time list of everyone experiencing homelessness in the community, from which we could work together to offer people support. It allowed us toÌýhave a shared, ongoing count of the number of people experiencing homelessness and how people were flowing into and out of the system. We never had thisÌýbefore. We reallyÌýdidn’tÌýknow how many people were experiencing homelessness and what their needs were,â€� said Marie.Ìý
This was theÌýfoundation of theÌýBuilt for Zero approach. It focused on making system improvements to generate an immediate impact. It allowed the community to work collectively to house people from a shared list, tracking progress each month and in real time.Ìý
“It gave us a pathway to focus our efforts, along with tools, individualized support, and continued opportunities for peer exchange in the work toward zero,â€� she said.Ìý
In 2017, Marie left the Region of Waterloo to become just the fifth staff member of CAEH — which now has more than 40 staff members — to lead the 20,000 Homes CampaignÌýand ultimately, BuiltÌýForÌýZero-Canada.Ìý
Building a movementÌý

Today, BuiltÌýForÌýZero-CanadaÌýhasÌýsupportedÌýmore thanÌý80 communitiesÌýacross the countryÌýin theirÌýwork to end homelessness.Ìý
More than 50 communities have high quality, real-time data. Many are reducing homelessness, and some had even reached functional zeroÌýfor a populationÌý— when local community systems are able to rapidly rehouse people when they fall into homelessness.Ìý
Since the 20,000 Homes Campaign launched, the communities supported through BuiltÌýForÌýZero-Canada have housed people more than 100,000 times.Ìý
None of that was true when Marie started with CAEH.
“If you think about the impact one person has had … MarieÌýhas easily touched the livesÌýof all those 100,000 people in one way or another,â€� saidÌýTim.Ìý
“She carried the whole thing onÌýher back by herself for a while and then built the team that became BuiltÌýForÌýZero-Canada. None of thisÌýwould’veÌýhappened without her,â€� he said.Ìý
The movement nowÌýhas access toÌýresources,Ìýfrom checklists and scorecardsÌýtoÌýa methodologyÌýofÌýcontinuous improvementÌýand failing forward:Ìýthings that MarieÌýpilotedÌýand introduced.Ìý
“Her approach is kind, solid, head down, do the work. And she is deeply, deeply committed to it,â€�ÌýTimÌýsaid.Ìý
Impact felt around the worldÌý
Amanda DiFalco, now the senior director of strategy and people with CAEH,Ìýhas worked closely with Marie for more than a decade, starting in the homelessness sector with the City of Hamilton.Ìý
At the time, Hamilton was also one of the first communities in Canada to conduct aÌýPoint-in-TimeÌýCount, andÌýlater joinedÌýMarie and the Region of Waterloo as one of the pilot communities withÌýCAEHº£½ÇÉçÇøÌýConnection and ActionÌýWeek and the 20,000 Homes Campaign.Ìý
As part of their groundbreaking work in the shift from managing to ending homelessness, Amanda and Marie were both selected toÌýrepresentÌýCanada at an Institute of Global Homelessness leadership program in India.Ìý
“We found ourselves in a room with homelessness leaders from across the globe, in a country and culture that was new to both of us. What struck meÌýwasn’tÌýany single moment — it was watching Marie move through that entire experience,â€� AmandaÌýsaid.Ìý
“Whether she was learning from a local leader, navigating a cross-cultural conversation, or simply exploring what was around us, she brought the same qualitiesÌýto every interaction: genuine curiosity, no pretence, and a real desire to understand before she spoke. SheÌýdidn’tÌýarrive with answers. She arrived with questions. And because ofÌýthat, peopleÌýopened upÌýto her,â€� she said.Ìý
When David Pearson first met Marie, he says there were just four Built for Zero/Advance to Zero communities in Australia.Ìý
“Honestly,ÌýIÌýdidn’tÌýreally know what I was doing.ÌýI was just so impressed with what had been achieved by Built for Zero-Canada,â€� said David, the CEO of the Australian Alliance to End Homelessness (AAEH).Ìý
“Now we have more than 30 communities and weÌýareÌýclear-eyed about our strategy, based on learning and our practice rooted in improvement. All of this is in no small part thanks to Marie. She has been an unwavering colleague, collaborator,ÌýmentorÌýand friend – always willing to share a resource, a checklist, anÌýinsightÌýor a supportive ear. She will be deeply missed from the international community of practice,â€� he said.Ìý
Melanie Lewis Dickerson, the chief programs officer with Field Impact in the United States, worked with Marie on the 20,000 Homes Campaign, and later to create Built for Zero-Canada.Ìý
“I’mÌýgrateful for her friendship, leadership, and support. She should beÌývery proudÌýof the lasting impact she has made in Canada and around the world,â€� Melanie added.Ìý
At the end of her career, Marie shares a note of gratitudeÌý
Looking back at her career, Marie says it has been an honour to work with so many mentors, friends, and leadersÌýwho have inspired and supported this work.Ìý
Marie says she wants to thank the people at the heart of this movement.Ìý
“Community leaders in Built for Zero are remarkable — not because the work is easy, but because they choose to lead where the work is hardest. They take systems that most people findÌýoverwhelming, andÌýturn them into coordinated action. They bring humanity into every room they enter, building trust across agencies, across sectors, and across lived experience. They insist on clarity, on real-time data, on seeing every person by name — because they know that precision is what makes progress possible,â€� said Marie.Ìý
“TheyÌýdon’tÌýwait for perfect conditions. They test, they learn, they adapt, and they try again. They build relationships that changeÌýwhatº£½ÇÉçÇøÌýpossible. They hold a bold vision and make it feel achievable. AndÌýperhaps mostÌýimportantly, they create cultures where hopeÌýisn’tÌýjust a feeling,Ìýitº£½ÇÉçÇøÌýa practice. These leaders are proving, community by community, that ending homelessness is not only necessary, but absolutely within reach.â€�Ìý
Marie saysÌýover the years, she has often thought of a quote by Jim Rohn: ‘Don’tÌýwish it were easier. Wish you were better.’Ìý
“I hope we have helped in a small way to make this work a bit easier, less lonely, and made us all better in working to achieve our mission to end homelessness,â€� said Marie.Ìý
Marie retires from CAEH on March 31, 2026.
