505 - 300B Fourth Avenue, St. Catharines, ON is yours on closing day. The conditions are gone, which means the deposit is committed and the deadlines from here are the kind that cost money rather than the kind that let you walk away. This is everything between now and a settled house, dated backwards from your closing rather than forwards from today.

Why this list is not the one your agent emailed you
Exactly 7 of these tasks can stop the closing. They are marked, and they are the only ones where being late means the transfer does not register and the lender does not advance.
The list is filtered to this house. A septic tank, a pool, an oil tank, a wood stove and a private well each add work that no generic checklist mentions, and a condo removes most of the outdoor half.
Around 70% of Ontario closings land on the last business day of a month, so movers, lawyers and utility appointments all bottleneck at once. A month-end closing needs the mover booked 35 days out rather than 18, and the plan says so when yours is one.
The cash calendar shows which week the money leaves. Down payment and land transfer tax are the two numbers every calculator gives you. The deposits, retainers and first-month charges that land in the same fortnight are the ones people borrow for.
Everything between here and settled
0 of 41 complete, 0% weighted
Weighted, not counted: a task that can stop your closing is worth 5 of the optional ones, so ticking off the doormat does not fill the bar.
41 outstanding, of which 0 are past a start date that has gone by and 20 are waiting on an earlier task. A date that has passed is usually a telephone call this afternoon. A task waiting on another one is not yours to start tonight.
Every date below is computed from this one. It is the only fixed point in a purchase, which is why the plan is scheduled backwards from it rather than forwards from today.
7 outstanding tasks can stop your closing
Not inconvenience. If any of these is not done, the transfer does not register, the lender does not advance, and your deposit is exposed.

The next fortnight, in order
Aug 28, 2026Have the seller serve the own-use notice before closing, if you are moving in
Firm to keys, in the order it happens
30 steps between now and Oct 27, 2026, by date rather than by category.
Why this list is ordered by date, not by categoryIn this stretch the only question is what is due next and whose job it is.
The sections further down carry the same steps with what each one costs and why this house calls for it.
Next outstanding: Have the seller serve the own-use notice before closing, if you are moving in, owed by your the seller, by Aug 28, 2026.
If it slips: You own a house you are not allowed to live in. A tenant who disputes the notice is heard at the Landlord and Tenant Board months later, and you carry the mortgage on it in the meantime.
If it slips: Nobody else can register the transfer, and a firm taking the file two weeks out has to search title, raise requisitions and get lender instructions inside whatever days are left.
If it slips: A hold that expires before closing means the rate is whatever is current on the day funds are advanced. On a long closing that is the difference between the payment you qualified on and one you have not seen, and a large enough move fails the lender's own ratios and reopens the approval.
If it slips: An unsigned commitment or one outstanding condition means no instructions reach your lawyer, and no instructions means no money on closing day.
If it slips: An insurer that discovers knob-and-tube or a 60 amp panel after binding can cancel mid-term, and a cancelled policy is a mortgage default clause.
If it slips: No lender advances mortgage funds without a binder on file, so the closing does not complete on the day and you are in breach of your own agreement.
If it slips: The last business day of the month is the busiest moving day in Ontario, and what is left when the good companies are full is a truck with no insurance and a cash price.
If it slips: A lawyer cannot register a transfer for someone they have not identified. The file stops until you are in the office, whatever day that is.
If it slips: Funds in trust are what your lawyer registers against. Without them there is nothing to close with, and a late closing carries interest and the seller's costs.
If it slips: After the keys change hands a missing fridge or a flooded basement is your repair. Before them it is a holdback your lawyer can negotiate.
If it slips: Registration queues on the last business day of the month. A mover booked for the morning is a mover charging waiting time on the driveway.
If it slips: The first time you need the water main is at 2am with water coming through a ceiling, which is the worst possible time to be learning the basement.
3 dates that come from your agreement, not from your closing date
Everything above is counted back from the closing date. These are not, because the agreement of purchase and sale sets them and every deal sets them differently. They are here without dates rather than with guessed ones. Your lawyer has all three on file, and the agreement is where the days are written.
You, through your agentDate set by the agreement
The deposit, delivered to the listing brokerage in trust
Certified funds or a wire to the listing brokerage's real estate trust account, not to a person. It is held there until closing and then credited to you on the statement of adjustments, so it is part of your down payment rather than on top of it.
Where the date is: The deposit clause of your agreement. Commonly within 24 hours of acceptance, sometimes on waiver of conditions, occasionally in two instalments.
If it slips: Late delivery is a breach of the agreement on its own terms, and the seller can treat it as one while the market is still moving.
Your lender, through an appraiser you do not chooseDate set by the agreement
The lender's appraisal, ordered and returned
The lender lends against the lower of the purchase price and the appraised value. An appraisal below the price does not cancel the deal, it reduces the mortgage, and the difference becomes cash you owe on closing day.
Where the date is: Inside your financing condition period, or immediately after firm on a deal financed without one.
If it slips: An appraisal that comes back late is the most common reason a mortgage commitment arrives days before closing, and a shortfall found that late has to be funded from savings or a second loan.
Your lawyerDate set by the agreement
The title search, and the requisition date
Your lawyer searches title and raises anything found: an open building permit, a work order, an easement across the driveway, an unregistered survey line, a lien from a renovation. After the requisition date, objections to title are out of time and become yours to deal with as the owner.
Where the date is: The requisition date is a stated date in the agreement, usually a set number of days before closing.
If it slips: A defect found after that date is not a reason to refuse to close. It is a title insurance claim if the policy covers it, and an owner's problem if it does not.

A buyer who wants the unit for themselves has to ask the seller to serve an N12 on their behalf before closing: sixty days notice ending on the last day of a rental period, plus one month's rent as compensation. Instruct your lawyer the day you go firm, because the notice period runs on the calendar and not on your closing date.
Why this house: The listing says the house is tenanted, so you inherit the tenancy on closing.
You own a house you are not allowed to live in. A tenant who disputes the notice is heard at the Landlord and Tenant Board months later, and you carry the mortgage on it in the meantime.

A transfer in Ontario is registered by a lawyer, so this is the appointment the rest of the file hangs off. Get the retainer confirmed and the fee quote in writing, including the disbursements and the title insurance premium, and send the firm the signed agreement of purchase and sale the day you retain them.
Why this house: Every buyer has to do this one.
Nobody else can register the transfer, and a firm taking the file two weeks out has to search title, raise requisitions and get lender instructions inside whatever days are left.
CriticalYour broker
By Sep 27, 2026 (30 days before closing)
A pre-approval or a commitment holds the rate for a fixed number of days from a date on the paperwork, commonly 90 or 120. We do not hold that date: it is on your commitment letter, and it is the one number in your financing that expires on its own. Read it, compare it with your closing date, and if the hold runs out first ask your broker in writing what happens to the rate and to the payment.
Why this house: Every buyer has to do this one.
Do first: Sign the mortgage commitment and return every condition
A hold that expires before closing means the rate is whatever is current on the day funds are advanced. On a long closing that is the difference between the payment you qualified on and one you have not seen, and a large enough move fails the lender's own ratios and reopens the approval.

Sign the commitment letter and clear the conditions attached to it: income confirmation, down payment source, appraisal, and anything the lender added after the fact.

Roof age, electrical panel and wiring type, plumbing material, heating source, and whether anyone will be living there. Wrong answers here are what void a claim later.

Get a bound policy, not a quote, effective 12:01am on the closing date, and have the binder sent to your lawyer. A quote is a price; a binder is coverage. The date on this row is not the closing date and is not a preference: the lender's instructions require the binder in your lawyer's file before it will release funds, and an insurer that comes back asking for a roof age, an electrical panel photograph or a WETT report turns a one-afternoon task into a three-week one.
Why this house: Every buyer has to do this one.
No lender advances mortgage funds without a binder on file, so the closing does not complete on the day and you are in breach of your own agreement.
ImportantYour lawyer

The lease or the terms of an oral tenancy, the current rent and the date of the last legal increase, the last month's rent deposit, and the interest owed on it. You become the landlord holding that deposit on closing, so it belongs on the statement of adjustments as a credit to you.
Why this house: The listing says the house is tenanted, so you inherit the tenancy on closing.
You inherit the obligation to return a deposit you were never given, and a rent you cannot prove is the lawful one, which caps what you can charge for years.

Exterior and property
None of it is yours to arrange. The corporation holds the roof, the grounds, the parking structure and the snow clearing, and bills you for them through the common expenses instead of asking you to book them. The part that is yours is its insurance deductible, which your own policy has to cover and which is in the immediate group.
The corporation owns the roof, the grounds and the parking structure, so most of this group is not yours to arrange. What remains is anything attached to your own unit.
Every trade on this list, with what the record says about its licence
A directory is only worth having if it answers three things: whether this person is allowed to do the work, whether they are insured if they wreck your house, and what the job costs. Ours answers all three per business, and says plainly that nothing on it was checked against a register.
What a credential state means here, exactly.
One credential at a time rather than one badge per business, with the issuer, the number and the date the record carries on the business's own page, so the register is yours to put the number to.
A date on a record older than 120 days reads as unchecked rather than as passed.
An expiry in the past overrides the state stored beside it, so a licence a record marks verified that ran out last month shows as lapsed.
Where a trade has no register to check against, the page says that instead of implying one.
Reading this over a homeowner's shoulder because you are the one doing the work? Join the provider network. A request for licensed work reaches at most 3 businesses whose records list the certificate that trade requires, you read the whole job before you commit to it, and what a lead costs is printed on that page rather than quoted on a call.
