I
The Ceremony Garden
180 seated · May to October
A walled perennial garden beneath the twin alders the estate is named for.
Caledon, Ontario · A restored 1872 estate
One wedding a day,
at the house on the millpond
Forty acres, three spaces, and a promise most venues won't put in writing: our prices are on this website, our Saturdays are on a public calendar, and the rain plan is a room you can stand in, not a sentence in a brochure.

How we do business
I
Prices, published
Every package fee and per-guest catering range is on the packages page. No vague "starting at," and no phone number needed to see them.
II
Saturdays, visible
Twelve months of Saturdays, marked open, held, or booked, on the availability ledger. It's what we'd want if we were the ones planning.
III
Rain plan, standing
The Conservatory is reserved with every garden ceremony, dressed and waiting. The call is made with you at 10 a.m., never for you.
The estate
Three spaces, one day, yours
II
The Great Hall
160 dining · 200 cocktail · Year-round, heated
The 1872 bank barn, rebuilt beam by beam under its original timber frame.
III
The Conservatory
60 dinner · 90 standing · Year-round
A glass-and-timber garden house at the edge of the kitchen garden, strung with warm bulbs.

From our couples
“We chose Alder House because it was the only venue that would tell us the price before we gave them a phone number.”
Caledon, ON · One wedding a day
Come stand in the garden
Photographs are honest here, but the garden at four o'clock makes its own argument. Tours run Wednesday to Sunday and take forty-five unhurried minutes.
