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
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.
The south wall in late May: wisteria week

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
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
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 people
A small, steady team: one director, two coordinators, a chef, a grounds crew, and a steward who stays near you all evening.
June Okafor
Venue director
Runs the calendar, the contracts, and the 10 a.m. rain call.
Theo Marchetti
Lead venue coordinator
Builds your timeline and floor plan, and is your main contact from signing to send-off.
Ines Kowalczyk
Weekend and winter coordinator
Runs every Estate Weekend and every Winter House wedding.
“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
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.
