Two Mounties in ceremonial dress flanked Flaherty's casket as dignitaries began filing into the Abilities Centre in Whitby, Ont., for the visitation today.
First among them was Ontario Lt.-Gov. David Onley. Former Bank of Canada governor Mark Carney was also among the VIPs greeting Flaherty's widow and three children.
The former federal finance minister and his wife, provincial Tory legislature member Christine Elliott, were supporters of the centre, located in Flaherty's riding.
A state funeral will be held Wednesday afternoon at St. James Cathedral in downtown Toronto.
Prime Minister Stephen Harper, NDP Leader Tom Mulcair and Liberal Leader Justin Trudeau plan to attend, along with several members of the Conservative cabinet.
Flaherty died suddenly at age 64 last Thursday of a suspected heart attack, less than a month after he resigned from cabinet.
Flags have been flying at half-mast on Parliament Hill and Canadians can sign an online book of condolences.
Note to readers: This is a corrected story. An earlier version had an incorrect spelling of Christine Elliott's surname and Mark Carney's first name.
