They were taken to the Queen Elizabeth Hospital in Charlottetown, where they were declared deceased. The P.E.I. coroner's office will determine the cause of death, Butler said.
Underhay is survived by his wife and another child.
Underhay was also a teacher at Birchwood Intermediate School in Charlottetown, a community volunteer and an avid trumpet player.
"Josh has been a dear friend and colleague of mine for many years, as a volunteer, musician, passionate cycling advocate and Green Party supporter," said P.E.I. Green Party Leader Bevan-Baker in a written statement.
"He has touched the lives of everyone who knew him, including the students he taught, fellow musicians and members of the party."
