Roger du Toit, Toronto architect, dead after cycling accident

A prominent Toronto architect has died a month after being struck by an SUV while cycling in Rosedale.

Roger du Toit, 75, died of his injuries on Sunday, his architecture firm DTAH confirmed on its website. Du Toit was a founding partner of the firm which, among many other projects, helped design the CN Tower.

"Roger's leadership in the realms of community and campus master planning, urban intensification, and innovative transportation planning is second to none," DTAH said in its statement.

Du Toit was struck at 8:23 a.m. at the intersection of Wrentham Place and Roxborough Street East. Toronto police said the cyclist was northbound and had entered the intersection when he was struck by a 43-year-old woman driving a Toyota 4Runner.

He suffered life-threatening injuries in the collision.

DTAH said du Toit died peacefully and surrounded by family. 

Police say the investigation is ongoing and asked anyone with information to contact traffic services at 416-808-1900 or Crime Stoppers anonymously.
