As World Refugee Day approaches on June 20, advocates and health experts are calling on the Canadian government to urgently address prolonged family separation for refugees. With wait times for family reunification now averaging more than four years, critics say the delays are causing irreparable harm to refugee families and imposing long-term costs on the health-care system and the Canadian economy.

The significant health, social and economic costs of prolonged family separation merit urgent action. These costs are borne by refugees and their families as well as municipal, provincial and federal governments.

People seeking refugee protection whose claims are accepted in Canada receive protected person status and are allowed to apply for permanent residence. They are permitted to include dependent children and spouses who are outside Canada on their permanent residence applications.

While accepted refugees and their family members are legally eligible for permanent residence in Canada, they must be admitted under the immigration levels for Protected Persons in Canada and Dependants Abroad. Because the number of people applying under these levels exceeds the number of spaces available, family separation currently lasts 50 months.

In 2024, the government of Canada announced major reductions in immigration levels starting in 2025. These reductions will further delay family reunification, prolonging refugees' bureaucratic limbo.

Studies document the several mental health consequences of the separation of children from their parent(s), and of spouses from their partner. These challenges intensify as the duration of the separation increases.

Medical associations around the world say family separation is a traumatic event that can cause developmental regression and higher rates of unexplained illness in children.

This trauma may stem from the sense of abandonment that children experience while being separated from their parents. In one study from 2005, an interviewee said:

"It was hard at first ... .The children thought that I had abandoned them. They considered me a traitor."

Despite the time and efforts invested in long-distance relationships, family breakdown may result from prolonged family separation, necessitating counselling or child protection services.

These mental health consequences not only have human costs. They also represent a financial burden for the Canadian government through the Interim Federal Health Care (IFHC) Program. After protected people transition away from IFHC, provincial and territorial governments pay for health costs associated with family separation.

Some children may also require school-based interventions, mental health services and counselling, the costs of which are also borne by provincial governments.

Protected people separated from their families also pay to maintain two households: one in Canada and one overseas. In a 2019 study, a refugee said that "sending remittances was more expensive than if they lived together in Canada."

Remittances not only represent a financial challenge to refugee families, they also result in indirect economic losses to Canada as funds leave the country instead of being invested in Canada.

Research shows that family separation also inhibits integration. The inability to find affordable child care in a single-parent household, for example, limits the ability to learn official languages, participate in community groups and find work opportunities.

For example, one woman from Afghanistan who had been waiting more than six years for reunification with her husband told researchers:

"In night I sometimes cannot sleep and I just walk and walk around the lobby of my apartment building. [...] I can no longer take care of my children when they're missing all the time their father. They need their father. Even sometimes my family asking 'where is he?' and other kids at my children's schools are asking."

This stress caused severe mental and physical health issues for this woman and her family, further limiting her ability to work.

These integration challenges mean fewer people can work to their full capacity, limiting participation in the Canadian economy. Delayed economic integration due to family separation results in lower tax revenues for all levels of the Canadian government.

Family unity provides refugees with the necessary support to manage the stresses of resettlement. Family reunification increases flexibility to adjust to a new country and culture without additional challenges.

As refugees and their families integrate, Canada benefits. They find work, pay taxes and contribute to their communities.

The United Nations declared June 20 to be World Refugee Day almost 25 years ago. Although it's just one day, it reminds us to honour refugees from around the world.

It is a good time for the Canadian government to work towards issuing temporary visas to eligible family members, allowing them to live in Canada while they await permanent residence.

The right to family unity is protected by international law. Canada's reputation as a leader in refugee protection is at risk if family reunification continues to be delayed.

The social, health and economic costs of family separation are both inhumane and unnecessary.
