Amid renewed world tensions over immigration, a former Bosnian refugee wants to track down the father and son who welcomed her family to Canada with a random act of kindness 21 years ago.

Tamara Ramusovic and her family came to Canada as refugees when she was nine, in 1995, partly because her father's Muslim background put them at risk back home. They didn't know the language, but they soon found themselves welcomed to the country by a friendly man and his son, who invited the family out for dinner after a chance encounter in the park.

"It's really one of our fondest memories of the first few weeks in Canada," Ramusovic, who is now a lawyer in Vancouver, told CTV News Channel on Thursday.

Ramusovic said she's concerned that welcoming attitude might be a thing of the past, amid rising anti-Muslim and anti-immigrant sentiment stoked by the Syrian refugee crisis of 2015, and the inflammatory rhetoric of Donald Trump's successful U.S. presidential election campaign.

"The attacks on various communities including refugees and immigrants… felt very personal in nature," Ramusovic said. She said she's bothered that she once had to flee Bosnia because of her father's Muslim background, only to see other barriers against Muslims potentially on the way in the West.

"Now to be in a world where there's a suggestion that Muslims wouldn't be allowed into the United States, that really hit home," she said.

Ramusovic hopes she can track down the individuals who welcomed her family to Canada 21 years ago, so she can thank them properly for their kindness.

The chance encounter took place at a park in Vancouver in 1995, at a time when Ramusovic's family was still acclimatizing themselves to their new country. Ramusovic, who was nine years old at the time, was at a park with her father and her brother, 7, when a Canadian man and his son invited them to play soccer. "At that point in time we only spoke about 10 words or phrases in English between the three of us," Ramusovic said.

Nevertheless, the father and son were eager to play with the three refugees, and afterward, they suggested going to dinner together.

Unfortunately, her father lost the man's contact info in the months after the dinner, so the Ramusovic family never got the chance to reconnect.

"We never had an opportunity to get back in touch and communicate the things that we couldn't back then," she said.
