Book your venue 12 to 18 months before the wedding, your photographer and music 9 to 12 months out, your florist and attire 6 to 9 months out, and hair and makeup 3 to 6 months out. Those are the windows Bridebook's Canadian planning checklist gives, and they hold up well in Northumberland County, Ontario. The one thing I would add: if your date is a Saturday in August or September, start at the early end of every range.
Key Takeaways
- Most couples in Canada plan their wedding over 12 to 18 months, according to Bridebook's Canadian checklist (updated July 15, 2026).
- August and September held 14.6% and 14.3% of Ontario's 216,118 marriages from 2023 to 2025, the two busiest months, in the Registrar General's monthly data.
- An Ontario marriage licence is valid for 3 months from the date it is issued, so it is the one item you cannot book early.
- The Town of Cobourg's Friday civil ceremonies are fully booked for 2026, and 2027 dates open on January 4, 2027 (checked September 26, 2026).
- The Knot's 2026 Real Weddings Study found US couples hired an average of 13 vendors, which is 13 contracts to line up in the right order.
The vendor booking timeline, month by month
Order first, months second. Each booking fixes something the next vendor needs to know: the date, the room, the headcount, the look.
| Months before | Book | Why at this point |
|---|---|---|
| 18 to 12 | Venue, planner, civil ceremony or officiant | The venue sets the date, the guest count and often the caterer |
| 12 to 9 | Photographer, videographer, band or DJ, caterer if the venue has none | Each can take one wedding a day |
| 9 to 6 | Florist, attire, rentals and tent, cake, a guest room block | These quote against your venue and season |
| 6 to 3 | Hair and makeup, stationery, transportation | Trial dates and printing need lead time |
| 3 months to 10 days | Marriage licence, final numbers to the caterer | The licence expires 3 months after issue |
Invitations go out 8 to 12 weeks before the wedding, per the same Bridebook checklist, so order them at the start of the 6 to 3 month window. Rentals and tents are my addition to that list. An outdoor reception without a tent is a bet on the weather, and tents have a date calendar like everyone else.
Why summer and fall dates go first in Northumberland County, Ontario
Demand piles into a few weekends. The Ontario vital events data counts 216,118 marriages registered across 2023, 2024 and 2025. June to October held 62.4% of them, and August and September alone held almost 29%. The 2024 and 2025 figures are still marked preliminary. In each of the three years, August and September were the two busiest months.
Every popular vendor in the county is selling the same handful of Saturdays, and a photographer, a band or a coordinator can work only one wedding on any of them. The second couple to ask hears no.
Civil ceremonies show it plainly. The Town of Cobourg's marriages page offers Friday ceremonies at 1, 2 or 3 p.m. for $400, and it reads "Civil marriage ceremonies are fully booked for 2026!" Spring, summer and fall 2027 dates open on Monday, January 4, 2027. If you want one of those Fridays next year, put that morning in your calendar now.
What to book first, and why it is the venue
Settle two numbers before you call anyone: a guest count within about ten people, and a total budget. Then the venue.
The venue decides more than the room. It often decides your caterer, your bar service, your music curfew and whether you need a tent. A golf club with in-house catering and a barn rented bare are two different weddings with two different vendor lists, so sign the venue before you ask anyone else for a quote.
The photographer comes next. Choosing one is a matter of taste, so give yourself time to compare portfolios while dates are still open.

When you have less than a year
A six-month plan works in Northumberland County, Ontario. It works best when the date moves instead of the plan.
Look at the off-season. From 2023 to 2025, no month from November to April held more than 6.1% of Ontario marriages, and January held 3.8%. Venues and vendors have far more open dates in those months, and a Friday or Sunday opens even more.
Then compress. Book the venue and the photographer in the same fortnight, send save-the-dates the week the venue signs, and choose vendors who publish their availability so you are not waiting on replies. What a long engagement mostly buys is choice of date.
Holding a date: deposits and contracts
A date is held when the contract is signed and the deposit is paid, not when a vendor says "that should be fine" in an email. Cobourg says it outright for its ceremonies: a date is not confirmed until the town has the signed agreement and payment in full.
Before you pay a deposit, ask three things. Is it refundable, and until when? What happens if the vendor cannot attend? When is the balance due? Put the answers in the contract. The questions to ask your wedding vendors post has the full list.
Write down every deposit and balance date. One list. Those dates are the backbone of a realistic wedding budget, because the money leaves your account in stages, starting months before the wedding.
The last three months
This is when the marriage licence comes in. The Government of Ontario says a licence "is valid for 3 months from the date it was issued", and the provincial fee is $75 before any municipal fee. Apply too early and it expires before the wedding.
It is also when a day of coordinator starts working with you, even if you booked them a year ago. Studio bookings follow the same logic: the Ali Rose Events Co. services page suggests six to twelve months' notice for a wedding or a large event, and two to three months for a smaller celebration.
For what happens in those final weeks, and on the day itself, the wedding timeline guide walks through it in order. Your next step today is the venue. If you tell me your date, your town and your guest count, I will tell you which bookings to make this month.
