Whose pool is it anyway

a Collingwood Phase 1 closing waited on an agreement between two corporations

A Collingwood buyer’s Phase 1 condo unit shares a pool, gym and parking structure with a still-unbuilt Phase 2 building. It is the reciprocal agreement dividing those costs between the two future corporations, not the developer’s own estimate, that will actually set this unit’s common expenses.

The problem

The Phase 1 condominium corporation is registered under Ontario’s Condominium Act, 1998 and the unit’s transfer can proceed, but the pool, gym and parking structure serve a Phase 2 building that has not yet been constructed or registered as its own corporation. It is the reciprocal shared-facilities agreement between the two future corporations — still being finalized between the developer and its counsel — that will actually set how those shared costs divide, not the developer’s own preliminary common-expense estimate quoted at the time of sale.

What the developer’s estimate could not settle

  • The preliminary common-expense figure quoted at sale assumed a specific cost split between Phase 1 and Phase 2 that was not yet contractually fixed anywhere
  • The reciprocal shared-facilities agreement, once registered, is what will actually bind both future corporations to a cost-sharing formula
  • Until that agreement registers, no one -- not the developer, not either corporation -- can certify the eventual split with certainty

The buyer was closing on a real, complete unit in a real, registered corporation. The uncertainty sat entirely in what the building next door would eventually cost this one, once it existed.

The numbers

The mortgage itself is sized to this unit alone, so the shared-facilities uncertainty next door never touched the qualifying arithmetic.

The insured purchase, Phase 1 unitAmount
Purchase price$398,000
Down payment (10%)$39,800
CMHC premium (3.10% at 90% LTV)+$11,104
Total insured mortgage$369,304
Ratio check at the qualifying rateFigure
Payment at the qualifying rate (6.90%), 25 years$2,564/mo
GDS (payment + $330 tax + $125 heat) ÷ $8,300 income36.4%
TDS (GDS numerator + $225 car loan) ÷ $8,300 income39.1%

36.4% and 39.1% sit comfortably inside CMHC’s 39% GDS and 44% TDS maximums, numbers that hold regardless of exactly how the eventual Phase 1/Phase 2 shared-facilities split lands, since this mortgage is sized to the unit alone -- a routine result set against a market where housing starts statistics show multi-phase condominium projects are an ordinary part of new supply.

The solution

A mortgage agent licensed under Ontario’s Mortgage Brokerages, Lenders and Administrators Act treated the shared-facilities uncertainty as a documentation condition to clear before closing, not a detail to take on faith.

First, obtained written confirmation from the developer’s counsel that the reciprocal shared-facilities agreement was in its final form. A verbal assurance that Phase 2 would “work itself out later” was not something a solicitor could rely on.

Second, confirmed the agreement would be entered into the land titles system against both corporations before or concurrent with final closing, rather than closing on a promise that registration would follow eventually.

Third, had the file’s own condo-fee estimate flagged as provisional pending that registration, so the buyer understood the quoted common-expense figure could still move once the agreement actually registered.

Written confirmation from developer’s counsel that the reciprocal shared-facilities agreement is in final form
Confirmation of the agreement’s registration timing relative to final closing
Condo-fee estimate flagged as provisional in the buyer’s own file notes
Standard insured final-closing documentation for income and down payment
Post-closing follow-up once the agreement actually registers
№ 05

The outcome

Final closing funded insured at 36.4% GDS and 39.1% TDS once the reciprocal shared-facilities agreement was confirmed registered against both corporations.

Both ratios sit comfortably inside CMHC’s 39% GDS and 44% TDS maximums. Ontario’s land transfer tax on the $398,000 purchase came to $4,445.

What to take from this file

  • 01A phased condominium’s shared amenities may be governed by an agreement between two corporations, not just the one you’re buying into. Confirm that agreement exists and is registered, not just the developer’s preliminary estimate.
  • 02A developer’s quoted common-expense figure at sale is not the same as a registered cost-sharing formula. Treat it as provisional until the reciprocal agreement is actually in place.
  • 03This is a final-closing file, not an interim-occupancy one. The unit and corporation are real and registered; only the shared-cost split with a future phase remains open.
  • 04The mortgage math itself does not need to wait on the shared-facilities question. A purchase sized to one unit qualifies on that unit’s own numbers, regardless of how a future phase’s costs eventually divide.

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

Illustrative in this file — lender-specific, not rules:

  • 4.90% contract rate — rates move daily; not a quote.
  • the developer’s preliminary common-expense estimate — the true split depends on the reciprocal shared-facilities agreement once both corporations exist; the estimate quoted at sale is not the final figure.
