Prime Minister Stephen Harper announced byelections for four vacant ridings Sunday – two in the Toronto area and two in Alberta – but not, however, for the Tory riding vacated by the death of former finance minister Jim Flaherty.

The Prime Minister’s Office has said it’s waiting to hold a byelection in Flaherty’s Whitby-Oshawa riding east of Toronto out of respect for his family.

Scarborough-Agincourt could be closer than the Liberals would like: Their grip on the popular vote has been slipping as Tories gained ground in this riding.

Trinity-Spadina, too, could be more competitive than expected, pitting veteran councillor Adam Vaughan (Liberal) against relative political newbie Joe Cressy in Olivia Chow’s old riding.
