Last frost date for Toronto?

Just wondering when is it safe to plant them outside.
Calendar says May 11-20 for Toronto.

Is it safe to start them now?

Probably, but there's never a guarantee. 14 day trend is all above 10C.

Cdn gardening recommendations / plant hardiness zones / frost dates
Will be updated in the next year or so
USA ... updated theirs recently

Saw this on the news about a week ago

Dates are based on a 20 year cycle / trend

Global Warming is definitely changing things here in the True North

May used to be quite a chilly month ... all over Canada
Hence the old adage... don’t plant until Victoria Day = May 24th to be safe

Now it looks like things are warming up & moving a tad earlier

And in big cities ... where Greenhouse Gases create a warm bubble
Impending Revised Dates are even earlier than ever before

In the meantime ...
General rule of thumb
Many plants can handle temps above 5 C = 40 F
But more “summery ones” ... be it Tomatoes, Peppers ... or tropical plants
Their minimum tends to be somewhere in the 10 C = 50 F ... to 15 C = 60 F range

So watch your weather forecast and nightly lows
And plan accordingly

My general rule of thumb is to wait until May 2-4 long weekend for planting. But looking at the forecast , I’d say now is fine.

Stopped reading after this and burst out laughing.
I would guess 80%+ of RFD isn't in the true north. Hell, there are a bunch of states that are further north than Toronto and Toronto has like what, 20% of our population?

It was snowing here 2 or 3 days ago for a little
bit. And it is -1 as I'm driving the truck (or according to the truck) and I wouldn't even consider this the true north

Why are you using your phone/posting on here if you're driving?

Hey ... glad I provided some humour in your otherwise bleak day.

Truth is the “True North” was a tongue in cheek comment for the Torontonian who posted this question
Guess you don’t follow Raptors basketball
Or know much about how many Cdns like to tease folks in Southern Ontario and tell them they live in Canada’s Banana Belt

Then again, a good lot of my reply
Was about climate change in Canada & global warming ...

Something based on your byline “ warming up the earth 1 gas fill-up at a time... You only live once, get a v8”
Tells me you care little about

Ah yes ... another science denier :facepalm:
