A 29-year-old man accused of drunk driving in a Toronto-area crash that claimed the lives of three children and their grandfather has been remanded in custody until his bail hearing on Oct. 19.

Marco Muzzo, glancing at his fiancee -- whom he was scheduled to marry on Oct. 17 -- was in handcuffs for his appearance.

Outside the courthouse, Muzzo's high-powered defence lawyer, Brian Greenspan, said his client wants to express his condolences to the family of the victims following the crash in Vaughan, Ont., on Sunday.

Muzzo, of King Township, Ont., is facing a dozen impaired-driving offences and six charges related to the dangerous operation of a motor vehicle after he allegedly smashed into the family's minivan.

Candlelight vigils were held Thursday for Daniel Neville-Lake, 9, his brother Harrison, 5, their sister Milly, 2, and the kids' 65-year-old grandfather who died following the crash.

The Muzzo family owns the construction company Marel Contractors and is worth nearly $1.8 billion, according to Canadian Business magazine.
