Weather in Toronto in May
May in Toronto is cool outdoor weather: usable if you dress for it, not a beach brief.
In Canada, this is how Toronto actually wears May, not how a country centroid would. Compared with July and January, May sits in the middle of Toronto's year.

What to expect
Daytime
Cool days in Toronto: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.
Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.
Rain
May is a wetter month in Toronto. Showers are part of the deal, not a spoiled surprise.
Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
Sun protection
Rain jacket
A layer for cooler evenings
