The allegations are detailed in a notice of hearing filed by the Ontario College of Teachers.  They describe the accounts of five students, dating back to 2015. All five were on a school team coached by Imgrund.
He resigned from the college on June 8.  She previously worked for the York Catholic District School Board as a division head in Newmarket.
It should be noted that no criminal charges have been brought against Imgrund.
A self-described “biostatist,” Imgrund has been posting daily COVID-19 analysis throughout the pandemic, amassing more than 90,000 Twitter followers.
He did not respond to requests for comment.  The charges have not been proven in court and no disciplinary hearing has yet been scheduled.
During an out-of-town tournament, charges say Imgrund messaged four students in a group message, linked to their personal phone numbers, late at night and into the early hours of the morning.  In the messages, he allegedly invited the students to accompany him to the resort pool.
“Get in the pool,” said one message.  “Grab your floaties and meet me at the pool” or words to that effect.
While in the room below the students, the college claimed that Imgrund “hit his ceiling/their floor” and called them late at night/early morning when they didn’t answer.
In another instance, Imgrund is accused of using a “technique that requires students to push their buttocks against him” with three of the athletes during a practice session.
The notice also describes separate accounts of Imgrund engaging in “inappropriate electronic communications” with students on an individual level.  On one occasion, he allegedly sent a picture of himself shirtless, saying, “If you don’t say I’m handsome, I’m going to cry,” or alert for that matter.
In another, the college accuses Imgrund of “soliciting and/or receiving photographs” of a female student showing her in a swimsuit.
Imgrund “yelled and/or berated” the student when she stopped responding to his messages, according to the notice, along with emailing the school’s guidance counselor asking to change her schedule when she was not placed in his class.
On one or more occasions, Imgrund is accused of taking the same student on “long drives” alone in his car.
He sent another student “numerous” messages stating he “wanted to get to know her as a coach and a player, not just a teacher and a student,” or words to that effect, the college said.  Imgrund is also accused of trying to Facetime the student and follow her on Instagram.
The college alleges that Imgrund asked a separate student “how things were going with her boyfriend,” along with offering to drive her to work and pick her up.
He is also accused of driving students in his car “at high speeds,” stating, “This is a cool zone.  You may swear,” the hearing announcement reads.
The York Catholic District School Board said it could not comment on the allegations when reached by CTV News Toronto on Saturday.
“Ryan Imgrund is not an employee of the York Catholic District School Board,” they said.  “The YCDSB cannot comment on a matter before the Ontario College of Teachers.”
