This year is the 60th anniversary of United Nations High Commissioner for Refugees (the UNHCR) and it is marking the occasion with a new campaign called One is too many.There are currently 15 million refugees and internally displaced persons in the world - that is 15 million stories of upheaval, dislocation, want and misery.Filmmaker Lynn Raineault has documented the stories of four of the luckier ones - those who found a way out of danger and despair and who have demonstrated incredible courage in rebuilding their lives. Here is her account of the making of the fourth story in her series - that of the Tayem family's journey from Iraq to Vancouver in Canada.
