You're right to question the 51% figure.  I don't have access to the GTA vote share, but here's how the Ontario vote share broke down on election night, from CBC.com on our election live thread:
 

ONTARIO
Party	Elected	Leading	Vote Count	Vote Share
LIB	75	0	2259987	44.67%
CON	24	0	1592368	31.47%
NDP	7	0	915291	18.09%
Last Update:  June 29, 3:05:32 AM EDT				106 seats

I think that 51% is for the entire GTA, including some outlying ridings on the rural fringe that don't really count. For the urban and suburban ridings, it was probably more like 56%, and for the City of Toronto, about 60%.
