Platt, who marks 60 years as a Catholic priest this year, is now enjoying a quiet retirement in the same Lockwood Road home he lived in as a young man.
He even attends and helps out with daily mass at the neighbouring Corpus Christi Catholic Church, the same parish he attended as a teen with his parents and nine siblings many moons ago.
"What goes around comes around. It's a complete circle. This was our parish 80 years ago," said Platt, who was also baptized at the local church.
"I feel at home. I feel comfortable here."
Platt is the eldest of 12 children, two of whom died in infancy. His brother Philip, who goes by his second name Wallace, also chose to become a priest and is celebrating 58 years of service this year.
Recently over 400 friends, former parishioners, colleagues and more than 150 family members gathered at Corpus Christi Parish to celebrate Platt's diamond jubilee anniversary.
Wallace even made his way home from his missionary work in Colombia to preach at the special mass.
Scores of Catholic dignitaries, namely reverends Peter J. Hundt, Henry Menses, Bernanrd Canning, Paul Casullo, Wilfred Firth, Edward Law, Walter Werbylo and George Zurek and Msgr. Edward Boehler and Ken Robitaille also celebrated Platt's day with him.
It was his strong and supportive Catholic family "where prayer was a daily activity" that led Platt to the priesthood.
"It was the good example of my parents. They were very devoted and very dutiful," he said, adding the family's faith in God helped them get through the tough times.
"We went through some very difficult times, especially during the Depression from 1929 to 1939, but somehow we got by."
Throughout his 60 years as a Catholic priest Platt has served at several churches starting with St. Paul's Parish on Queen Street East from 1948 to 1952. He was then at Holy Name Parish at Pape and Danforth avenues for five years. Next was an appointment at St. Cecilia's Parish in the city's west end for just under five years.
In 1962, Platt was sent to St. Mary's Parish in Victoria Habour, a small northern Ontario community near Midland.
"I thought it was the end of the world. The place is desolate but it's a great summer place," he said.
"It was a very supportive congregation."
About a year later in 1963, Archbishop Pocock invited him to serve as the founding pastor of the new St. John Fisher Parish in Bramalea.
A short time later, Platt was again asked to serve as a new parish's founding pastor. This time it was for Scarborough's St. Thomas More Parish, near Ellesmere Avenue and Markham Road. He served there for 16 years.
His last parish prior to his retirement was St. Luke's in Thornhill.
Platt said the thing that keeps him strong is his faith, perseverance as well as daily prayer.
"Society is all about me, right here, right now but human nature doesn't change. God doesn't change and our relationship with Him doesn't change. We have to realize that we're spiritual as well as rational," he said, pointing to the reason he chose to become a priest.
"Helping people is its own reward. It's gratifying."
Platt will continue his love of charity and giving long after he's left this earth through an endowment fund for diocesan priests called The Father Edwin J. Platt Professorship in Theology Fund at St. Augustine's Seminary. This special scholarship was established in honour of his 50th anniversary as a priest in 1998.
In lieu of gifts for his 60th anniversary, Platt invited his loved ones to donate to that fund.
