A Toronto man who flew to surprise his youngest sister in Paris was en route to visit his in-laws in Cairo when he died aboard an EgyptAir flight that crashed into the Mediterranean Sea Thursday.

Medhat Tanious, 54, was one of two Canadians among 66 victims of the mysterious crash.

Hundreds of mourners attended his funeral in Markham, Ont. Monday.

The victim's daughter, Merna Tanious, said her family needs answers.

“It’s been very tough not knowing what happened to my father in his last couple of minutes,” she told CTV News.

Tanious said she, her mother Gehan Erian and sisters Marina and Mariem are seeking solace for his death by remembering his impact on others.

"He had a heart of a child," Merna Tanious said in a telephone interview from Toronto. "He loved unconditionally, and he had an unbelievable ability to forgive all people that did him wrong."

Medhat Tanious spent much of his life in Egypt before immigrating to Canada with his wife and three daughters in 2004.

He had a gift for connecting with people, said his daughter, who declined to discuss what he did for a living.

He would cheer everyone around him. He fit into every single generation from the seniors to the teenagers," Merna Tanious said. "He can sit with anybody and make them laugh."

Officials from EgyptAir offices in Canada attended the funeral service, where a message from Egypt's Consul General for Canada was recited to the mourners.

The other Canadian on Flight 804 was Marwa Hamdy, who lived in Saskatoon before moving to Cairo for post-secondary studies. She married an Egyptian and raised her three sons there.

The cause of the crash still has not been determined. Ships and planes from Egypt, Greece, France, the United States and other nations are searching the Mediterranean Sea for the jet’s voice and flight data recorders.

Body parts recovered showed signs of burns and were so small that they suggested the jet was brought down by an explosion, a member of the team examining the remains said Tuesday. But the idea of a blast was promptly dismissed by the head of Egypt's forensic agency as "baseless" speculation.
