Harbour Ten10 at 1010 Dundas St E in Whitby is a 110-suite residential building completed in 2024 by Castle Group, currently showing two active listings out of 7 available units across the Whitby submarket, representing a 1.8 percent availability rate. Recent leasing activity includes one closed lease in the trailing 30 days at an average of $2,100 per month with a 10-day time on market, and two additional leases in the 90-day window averaging $2,500 per month with a 12-day DOM.

The two active listings carry an average asking rent of $2,525 per month at a blended rate of $3.42 per square foot across an average 771-square-foot footprint. By comparison, the three tracked historical leases realized an average of $2,467 per month at $3.52 per square foot over a smaller average 717-square-foot suite. The active inventory therefore offers more space at a lower rate per square foot than what previous tenants paid, while the submarket asking benchmark sits at $3.56 per square foot, placing Harbour Ten10 roughly 3.9 percent below the broader Whitby asking rate.

Marketing friction is moderate: the active listings have averaged 31 days on market, nearly double the Whitby submarket benchmark of 16 days, signaling a leasing deceleration despite the building's zero-termination record. One delisted unit sat for 175 days at an average asking rent of $2,550 per month, which was $450 above realized lease averages, indicating that overpriced inventory in this building tends to stall. Tenants who did close secured an average concession of $50 per month, or 1.96 percent below asking, across all tracked leases. Inventory depth is thin: one 1-Bedroom and one 2-Bedroom + Den are available, meaning renters face single-unit scarcity in both tiers with no multi-option choice within the building.

Active Market Insights & Questions

How has rental availability changed at Harbour Ten10 recently?

Harbour Ten10 has 2 active listings as of August 31, 2026, with asking rents ranging from $2,150 to $2,900 per month, an average of $2,525 and a median of $2,525. The two suites average 771 square feet at a blended asking rate of $3.42 per square foot. Inventory is split evenly between a compact 1-Bedroom entry suite and a spacious 2-Bedroom + Den executive layout, so there is no clear lean toward either end of the spectrum; each tier is represented by a single listing.

What floor plans and unit layouts are currently available at Harbour Ten10?

The dominant active layout at Harbour Ten10 is the 1-Bedroom, with one listing representing 50 percent of available inventory at an average asking rent of $2,150 per month over 550 square feet, or $3.91 per square foot. The remaining 50 percent is a single 2-Bedroom + Den unit asking $2,900 per month across 992 square feet at $2.92 per square foot. Both tiers are single-listing samples, so no tier offers a comparative spread within the building.

What is the average asking rent and $/SF by suite size at Harbour Ten10?

Harbour Ten10's active asking rents span from a minimum of $2,150 per month to a peak of $2,900 per month, a dollar spread of $750 or 34.9 percent. The median asking rent sits at $2,525 per month. The entry-level suite is a 1-Bedroom at 550 square feet priced at $3.91 per square foot, while the peak offering is a 2-Bedroom + Den at 992 square feet priced at $2.92 per square foot, reflecting the inverse relationship between suite size and unit rate.

How much extra do parking spaces and dens cost at Harbour Ten10?

Harbour Ten10's active den premium and square-footage delta are unquantified due to insufficient paired listings for a reliable comparison. Marginal cost per square foot for additional den space therefore cannot be isolated from the current two-unit sample. Active parking stall premiums also cannot be reliably isolated, as the paired data set contains anomalous outliers or an insufficient sample to produce a defensible figure.

How do asking rents at Harbour Ten10 compare to local and municipal benchmarks?

Harbour Ten10's average asking rent of $2,525 per month and $3.42 per square foot both sit below the Whitby submarket asking benchmarks of $2,657 per month and $3.56 per square foot, a 3.9 percent discount on the rate metric. The nominal rent gap narrows when accounting for suite size: the building's active average footprint of 771 square feet exceeds the submarket norm, so the lower per-square-foot rate partly reflects larger unit configurations rather than a pure price concession. Harbour Ten10 accounts for 2 out of 7 available listings in the Whitby submarket, or roughly 29 percent of current inventory.

Leased Transaction Insights & Questions

How many suites were leased at Harbour Ten10 last month, and how fast did they rent?

Harbour Ten10 at 1010 Dundas St E in Whitby closed one lease in the trailing 30 days with a 10-day DOM, compared to a 12-day DOM across the 90-day window and a 16-day submarket benchmark. The 90-day window captured two closed leases, while the full lifetime record shows three total transactions since the Castle Group project registered in August 2024. Leasing cadence has moderated from the initial post-delivery burst into a steady one-unit-per-month pace, consistent with a building that is still working through its first full year of occupancy.

What is the negotiation spread between asking rents and closed lease prices at Harbour Ten10?

Harbour Ten10 tenants negotiated an average discount of $50 per month (1.96% below asking), translating to $600 in annual savings per unit across the three tracked leases. One out of three leases—33.3%—closed at a price below the landlord's listed rate, confirming measurable tenant leverage in this Whitby submarket. The remaining two transactions settled at or near asking, indicating that the discount pattern is real but not yet universal across the building's lease pipeline.

What are typical executed lease prices across different layouts at Harbour Ten10?

Harbour Ten10's three closed leases split evenly across three distinct layouts, each representing an individual single transaction rather than a broad statistical benchmark. The 1-Bedroom tier (550 sq ft) leased at $2,100 per month with a 10-day DOM and a rate of $3.82 per square foot. The 1-Bedroom + Den tier (650 sq ft) closed at $2,400 per month after 51 days on market, pricing at $3.69 per square foot. The 2-Bedroom + Den tier (950 sq ft) leased at $2,900 per month with a 13-day DOM and a rate of $3.05 per square foot. Because every tier reflects a single deal, these figures should be treated as directional data points rather than reliable market averages.

What measurable rent premium did suites with parking achieve in closed leases at Harbour Ten10?

Harbour Ten10's leased parking premium cannot be reliably isolated from the available transaction data, as the paired sample is insufficient to separate a standalone parking charge from bundled suite rents. Active listings at the building also show an unreliable or outlier parking figure that does not support a defensible premium estimate. Prospective tenants should confirm whether parking is included in the quoted rent or billed separately before signing a lease.

How does the lease-to-listing ratio at Harbour Ten10 reflect current tenant demand?

Harbour Ten10's three tracked leases show a non-linear rent trajectory from May through August 2026, with the highest nominal rate landing in June and the lowest in August. In May, one 1-Bedroom + Den unit (650 sq ft) closed at $2,400 per month, $3.69 per square foot, after 51 days on market. In June, one 2-Bedroom + Den unit (950 sq ft) leased at $2,900 per month, $3.05 per square foot, with a 13-day DOM. In August, one 1-Bedroom unit (550 sq ft) closed at $2,100 per month, $3.82 per square foot, after just 10 days. The August drop in nominal rent reflects the compact 550 sq ft footprint rather than any devaluation of the building; the per-square-foot rate actually rose to the highest level of the three months.

De-Listed Market Analysis & Questions

How many listings de-listed at Harbour Ten10, and what was their re-listing price compared to previous asking?

Harbour Ten10 logged one delisted listing against one trailing-30-day lease, producing a delisted-to-leased ratio of 100% for that window (33.3% against the lifetime total of three leases). The single delisted unit expired rather than being terminated or suspended, suggesting the landlord allowed the listing to lapse rather than actively pulling it. At a 110-suite scale, one expired listing is a minor friction signal, but the 1:1 ratio in the 30-day window warrants monitoring to confirm it does not harden into a recurring pattern.

How do asking prices on de-listed suites compare to executed leases and active listings at Harbour Ten10?

Harbour Ten10's single delisted unit asked an average of $2,550 per month, which is $450 per month above the $2,100 realized lease average in the trailing 30 days. The delisted listing also carried a rate of $3.92 per square foot versus the 30-day realized rate of $3.82 per square foot, confirming direct overpricing relative to what tenants actually paid. This spread indicates the landlord's asking price exceeded market-clearing levels by roughly 21%, a gap that ultimately drove the listing to expire unrented.

What market friction causes rental listings to stall or de-list at Harbour Ten10?

Harbour Ten10's delisted unit sat on market for an average of 175 days, compared to a 25-day realized lease DOM across the building's lifetime record. That 150-day excess represents five months of lost rent at the $2,550 asking rate—$12,750 in foregone revenue—plus ongoing condo maintenance fees for the duration. Even measured against the tighter 30-day realized DOM of 10 days, the excess stretches to 165 days, underscoring that the overpriced listing consumed well over four months of carrying cost before expiring.

12-Month Market Dynamics & Trend Trajectory

Harbour Ten10's lifetime average realized rent of $2,467 per month sits 2.5% below the Whitby submarket average of $2,531, while its $3.52 per square foot rate runs roughly in line with the submarket's $3.50 per square foot benchmark. The building's active asking inventory averages $2,525 per month at $3.42 per square foot, placing it 3.9% below the submarket's average asking rate of $3.56 per square foot and signaling a modestly competitive pricing posture relative to neighbouring Whitby rentals. On pricing discipline, one of three tracked leases—33.3%—closed below the landlord's asking price, with tenants securing an average $50 per month (1.96%) discount that equates to $600 in annual savings per unit. The remaining two leases settled at or near asking, so the concession pattern is present but not yet dominant. This tenant-favorable negotiation dynamic suggests landlords at Harbour Ten10 are still calibrating their asking prices against what Whitby renters will actually sign, and prospective tenants should expect room to push back on price, particularly on the smaller 1-Bedroom suites.

Nearby Building Rental Comparables & Price Spreads

Direct rental rate comparisons against residential properties in the immediate vicinity.

Harbour Ten10 at 1010 Dundas St E sits in a tight Whitby pocket where its only active pricing competitor is Station No. 3 at 201 Brock St S, 1.36 kilometres away, also completed in 2024 and recording three closed leases over the trailing 180 days. The remaining three comparables—210 Gilbert at 210 Gilbert St (1.33 km, built 1991), The Waldorf at 711 Rossland Rd E (2.03 km, built 1992), and Connoisseur at 712 Rossland Rd E (2.24 km, built 1992)—each logged zero lease transactions in the same window, functioning as architectural and amenity references rather than live pricing benchmarks. This splits the local field into a single modern-generation peer with realized volume and three legacy mid-1990s buildings that carry no current rental data. The immediate micro-market benchmark, drawn from the sole active competitor, sets an average realized rent of $2,600 per month at $3.62 per square foot across 717 square feet of interior space. Harbour Ten10's three closed leases averaged $2,467 per month at $3.52 per square foot over the same 717-square-foot footprint, placing the subject $133 below the comp benchmark and $0.10 per square foot under the peer rate. Against the broader Whitby submarket average of $2,531 per month and $3.50 per square foot, the subject's realized pricing sits modestly above the submarket rent but marginally below the submarket rate per square foot, reflecting a 2024 build with a full amenity suite that justifies a small premium over the legacy stock while remaining competitively priced against its same-generation rival.

Comparable Analysis & Questions

How do rental rates at Harbour Ten10 compare to neighbouring buildings within Whitby?

Harbour Ten10's average realized lease rent of $2,467 per month runs $133 below the overall comp benchmark of $2,600, a gap driven entirely by its sole active competitor, Station No. 3 at 201 Brock St S (1.36 km, three closed leases, $2,600 average rent, $3.62 per square foot, 717 square feet). The three remaining comparables—210 Gilbert (1.33 km, built 1991), The Waldorf (2.03 km, built 1992), and Connoisseur (2.24 km, built 1992)—each recorded zero closed leases over the trailing 180 days and therefore carry no realized rent or per-square-foot benchmark to reference. In practical terms, Harbour Ten10 is the only 2024-completed building in this cluster with a second data point for direct rent comparison, and it trades at a 5.1 percent discount to Station No. 3 on a month-to-month basis.

Does Harbour Ten10 offer a competitive price-per-square-foot ($/SF) against local comparables?

Harbour Ten10 offers 717 square feet of interior space at $3.52 per square foot, a rate that sits $0.10 per square foot (2.8 percent) below Station No. 3's $3.62 per square foot while delivering an identical average suite footprint. Because the subject and Station No. 3 share the same 717-square-foot average, the $133 monthly rent gap is not a function of a smaller interior; it reflects a genuinely lower rate per square foot at the subject, making Harbour Ten10 the more cost-efficient option on a space-adjusted basis. Against the Whitby submarket average of $3.50 per square foot, the subject's realized $3.52 per square foot is essentially at parity, confirming that the building's 2024 construction and full amenity package are priced in line with the broader market rather than commanding a structural premium over its same-generation peer.

How do building age, amenities, and developer reputation impact rent spreads?

Harbour Ten10 fields a nine-item amenity suite—Concierge & Security, Gym & Fitness Centre, Yoga Studio, Games & Billiards Room, Party & Lounge Room, Meeting Room, BBQ Area, Children's Playground (Outdoor), and Zen Space—that differentiates it from Station No. 3 through community and wellness programming while lacking the aquatic and outdoor-living features that define the legacy Rossland Rd E buildings. Specifically, the subject's Children's Playground and Zen Space appear in no nearby competitor, and its Games & Billiards Room and dedicated Meeting Room are absent from Station No. 3, which instead offers a Pet Wash Station, Rooftop Terrace, Garden & Courtyard, and Business Centre. The Waldorf and Connoisseur both feature Indoor Pools, Hot Tubs & Jacuzzis, and Sauna & Steam Rooms—aquatic and spa facilities Harbour Ten10 does not provide—positioning the subject as a modern, family- and wellness-oriented community building that best serves young professionals and small families seeking a 2024-built residence with structured social and fitness programming rather than resort-style aquatic amenities.

Data Methodology & Analytical Standards

How FastScreen aggregates public listing records, tracks active inventory, and calculates rental market metrics for Harbour Ten10.

Snapshot Dates & Benchmark Cadence

  • Standardized Snapshot: Market metrics reflect a standardized monthly snapshot locked as of August 31, 2026.
  • Benchmark Comparison Cadence: Month-over-month comparisons evaluate changes across standardized month-end reporting windows (August 2026 vs July 2026), ensuring consistent baseline periods and eliminating intra-month reporting volatility.
  • Point-in-Time Daily History: Daily charts capture point-in-time active listings available on any given calendar day.

Public Data Aggregation & Thresholds

  • Public Data Aggregation: FastScreen aggregates residential rental listing and completed lease transaction records from publicly available sources.
  • Threshold Filtering: All listings are subject to a minimum monthly rental threshold of $1,000 to filter out standalone storage lockers, private parking spaces, and misclassified commercial entries from condominium statistics.

Calculation Formulations

  • Average Asking Rent: Weighted average of active asking prices across available suites in the reporting period.
  • Price Per Square Foot ($/SF): Calculated by dividing rent by square footage only for listings that provide unit dimensions (suites without stated square footage are excluded from $/SF calculations).
  • Days on Market (DOM): Measures elapsed calendar days between the date a suite is first listed and either the benchmark snapshot date (for active listings) or the finalized date leased.
  • Parking & Den Differentials: Average asking rent differences between suites with vs. without parking, and suites with vs. without a den.

Data Limitations & Scope

  • Exclusively Public Records: Statistics are derived exclusively from publicly available rental listings and completed lease records. Private direct-to-landlord arrangements, unadvertised tenant renewals, and off-market rental agreements are not captured.
  • Agreed Contract Amounts: Reported lease amounts reflect agreed contract rents and do not account for private move-in allowances or individual unit renovations that may influence pricing spreads.
