The North has historically voted orange, smaller cities and Toronto flip orange/red, and the suburbs/exurbs around Toronto are solid blue. There is one green MPP in Guelph who's pretty tight.

Edit: It's kind of all over the place. Decades of Progressive Conservative governments until the 80s, then Liberals and NDP each formed a government. The PCs with Mike Harris got in twice in the 90s and fucked it up spectacularly enough to usher in nearly 20 years of Liberals, until people decided they didn't like Katherine Wynne and voted in the dumbest asshole imaginable with the current government. The working class/ libertarian dudes up in the North tend to vote NDP, while the urban gentry and downtown pinkos tend to vote center-right Libs or succdem NDP. The key to the Tories last election is the 905 belt of suburbs around Toronto, which is populated by petty boug, recent immigrants from socially conservative countries, real-estate developers, and dudes who drive trucks (inclusive), who's only priorities are a) low taxes, b) more roads, and c) owning "downtown elitists". This is also the most rapidly-growing demographic/ area in the province, so it's vote-rich and necessary for anyone hoping to form government. Doug Ford was born directly out of their self-interested malice, the fetish for shitbird small-business tyrants everywhere, and also happens to be deep in the pockets of every slumlord developer who wants to pave the province with cardboard houses and 20-lane highways from Lake Ontario to Thunder Bay.
