Liberal MPP Greg Sorbara will reportedly announce Wednesday morning he's stepping down.
The Star reports he is retiring from politics to spend more time with his family.
That means a by-election will be called in Vaughan, marking the second fall by-election in Ontario. The other will be in Kitchener-Waterloo.
Sorbara has been at Queen's Park for over 20 years, both as an MPP and a cabinet minister.
