A cycling advocate who was killed while biking in Toronto last month is being remembered with a memorial ride on Friday.

Gary Sim was biking in the Rockcliffe-Smythe area on June 30, going westbound along a sidewalk on Alliance Avenue. He was approaching Jane Street when he was struck by a van attempting to turn right into the driveway of a home.

Sim was rushed to hospital in life-threatening condition, according to police. On July 2, he succumbed to his injuries.

His daughter, Kristen Campbell, said she often joined her father on bike rides.

"He even rode in the winter. As long as the road was clear he'd be on his bike. So he was, as far as my memory of him is, always cycling."

A group of riders are expected to gather around 6 p.m. at Matt Cohen Park, located at the corner of Spadina Avenue and Bloor Street West. They plan to start riding at 6:30 p.m. and take a route to the crash site to honour Sim.

The 70-year-old often posted on Twitter about cycling and was an advocate for bike safety. The latest tweet from his account was posted the day he died by his family, and has been retweeted more than 100 times.

“#BikeTO This is my last tweet as I pedal my ghost bike with you all,” the post reads.

“I was struck down 06/30 while riding and did not survive #sharetheroad.”

Campbell said her family made the tweet “short and simple, just to get it out there so people know what happened.”

“Remember that there is a life at the other end of that. It’s not just a bicycle. There’s a person on that and they have a life and you’re affecting not just them,” said Campbell.

“You’re affecting everyone around them.”

The 62-year-old man who was driving the van was later charged with making an unsafe turn.

He is scheduled to appear in court on August 17.
