Understand Saint-Eustache before you commit to an address
Saint-Eustache is forty-seven thousand people north-west of Laval on the Rivière des Mille Îles, an old parish best known for the 1837 rebellion battle fought in and around its church, which still carries the cannonball damage. It charges 0.4404% on a median detached house assessed at $472,100, which produces the second-lowest municipal bill of any city over forty thousand people on this list, after Mirabel's. Figures come from the province's assessment roll and municipal budget file, measured the same way in all 28 municipalities here.
The cost of living in Saint-Eustache, and what a home costs
Two calculators on Quebec's own rules: semi-annual compounding and the real minimum down payment tiers, and the closing costs this province actually charges.
Rent or buy in Saint-Eustache
Whether buying here beats renting, and the year it turns over. Both households start with the same cash, so the comparison is not rigged either way.
Mortgage calculator
Semi-annual compounding, the CMHC premium under twenty percent down, and the 9% Quebec sales tax charged on it in cash at closing, the highest in the country.

What buying in Saint-Eustache actually involves
About $2,100 a year. Saint-Eustache combines a moderate rate with modest assessments and a decent industrial and agricultural base, and the result is genuinely inexpensive ownership within half an hour of Laval and forty minutes of downtown outside peak. The old core around the church and the river is attractive and walkable in a way most Rive-Nord suburbs are not.
The transit question is specific here: the REM's Deux-Montagnes branch terminates in the next municipality, not this one, so the fast run downtown is a bus or a drive away rather than a walk. That is still a large improvement on what existed before 2023, and it is the main reason this sector has been repricing. The road commute is Highway 640 and the 13 or 15, and the crossing points onto Laval are the constraint.
The old core around the church and the river is genuinely historic and quite separate from the subdivisions and the industrial areas that make up most of the city. Prices, housing age and character all differ across that line, and the municipal figure sits between them.
The river and the lake are the flood consideration here, and the recent spring floods in this part of the region were serious enough that mapping and protection works have been revised since. Any property near the water should be checked against the current mapping rather than an older one.
Moving to Saint-Eustache: check these before you commit
- How you would actually reach the Deux-Montagnes REM terminus, and the parking situation there.
- Flood mapping along the Rivière des Mille Îles, which affected this municipality in both 2017 and 2019.
- Agricultural zone boundaries, which cover a large share of the territory and are permanent.
- Current flood mapping near the river and the lake, which has been revised in recent years.
- Whether the address is in the historic core or the subdivisions, which are different markets.
The 9,543 detached one-dwelling houses on Saint-Eustache's 2026 roll are what the median above describes. The roll was built against market conditions on 1 July 2023 and is fixed for three years, so it is a market value rather than a current one.
Sourced, dated, and separated from the guesswork
Every Saint-Eustache figure below is cited, stamped with the period it describes, and editable, because a number for the whole city rarely describes your purchase. Appreciation and investment returns are assumptions rather than facts, and they are labelled that way. Read the methodology for how the line is drawn.
- Prices, rents and tax rates: published statistics and the official schedules.
- Nothing here is a lender quote, a pre-approval or financial advice.
