Borys was born in 1953 in Fort William, Thunder Bay, north of Ontario. Thunder Bay at that time, was a very interesting place, a lot of Ukrainians moved there after World War II, because they could find a job. When he was three, the Sirskyj family moved to Toronto, and in 1962 to Waterloo.

  One of the unforgettable memories: in the Winter of 1971, 7 members of Canada's Plast Youth Association - Borys Sirskyj, Zirka Rad, Mykhajlo Hansh, Darka Sharanevych, Vasyl Pavlenko, Oleh Kandyba, Omelan Tarnavsky and one member of Plast from the USA, Paul Dorozhynsky, flew to Australia for the celebration of the 60th anniversary of Plast. It was the first Plast delegation to visit Australia. They spend 22 hours in an airplane and were welcomed by about 300 people. In Australia, the mornings were really hot 110°F, and in the night the temperature dropped down to 54°F. In the camp place lived many kangaroos and koala bears. It was the chance to meet members of Plast from all around the world and become closer to Plast in Australia.

In the 70's, the Soviet Union started the violations of the human rights and repressions. Many political activists were arrested and one of them was Valentyn Moroz. At that time Borys Sirskyj was the head of the University of Waterloo Ukrainian Students Club which also included members of Plast and other Ukrainian youth organizations. In 1974 the Club actively organized and participated in demonstrations against the violation of human rights. To start their protest they announced a hunger strike to free Valentyn Moroz and others. Students told everyone about Ukraine, its history and political sitation, wrote protests, were on TV and in the newspapers. Priests and many people came to celebrate masses. About 500 students from St. Mary's and members of Plast from Toronto came to sign the petitions for the protest and took part in the hunger strike. This action spread throughout Canada, there were 15 hunger strikes in different places. After 10 days the hunger strikes ended and some students were taken to the hospital.

The most memorable things for Borys Sirskyj are samples of soil from Chornobyl and from the grave of Taras Shevchenko in Kaniv, Ukraine. Borys Sirskyj worked as a Canadian diplomat in Europe and during his visit to Ukraine, he was allowed to go into the Chornobyl Zone, close to the reactors, where he got the sample of soil. He also visited Kaniv and other places in Ukraine. This soil samples reminds him of Ukraine and the tragedy of Chornobyl, and how many effort has to be done to build Ukraine as a prosperous independent country.

Borys is a member of Ottawa Plast organisation for many years, he was a representative to the High Plast Command (HPC) in 1975-1980 and was a counsellor for younger members of Plast. He belongs to the "Hajdamaky" group.
