Hillside I — Rental Market Data

Hillside I at 18 William Carson Cres has one active listing as of August 31, 2026, with an asking rent of $3,650 per month (minimum, median, and maximum all identical given the single unit). The available suite spans 1,100 square feet at an asking rate of $3.32 per square foot. This 100 percent share of active inventory is a 2-Bedroom + Den layout, placing the building's current availability squarely in the multi-bedroom executive tier rather than compact entry-level one-bedroom stock.

The sole active layout at Hillside I is the 2-Bedroom + Den, representing 100 percent of available inventory with one listing at $3,650 per month. That single unit offers 1,100 square feet at $3.32 per square foot, and no other bedroom tier—whether one-bedroom, standard two-bedroom, or three-bedroom—currently has an active listing. Renters seeking a different configuration must source from the remaining four active listings in the York Mills submarket.

Hillside I's active pricing spread is $0, as the single available unit lists at $3,650 per month with no range to measure. The entry-level and peak suite are the same 2-Bedroom + Den layout at 1,100 square feet and $3.32 per square foot, so there is no internal tier differentiation to evaluate. With only one unit on the market, the median asking rent equals both the minimum and maximum at $3,650 per month.

Hillside I's active den premium cannot be quantified because the single available listing is itself a 2-Bedroom + Den configuration, leaving no paired 2-Bedroom unit to isolate the marginal cost of den space. Parking stall premiums are likewise unquantifiable; the data sample is insufficient or contains anomalous outliers, so no reliable per-month parking add-on can be stated for this building's active inventory.

Hillside I's active asking rent of $3,650 per month and $3.32 per square foot both trail the York Mills submarket asking benchmarks of $4,000 per month and $3.60 per square foot, a 7.8 percent discount on the rate per square foot. The nominal rent gap of $350 per month is partly explained by suite sizing: Hillside I's 1,100-square-foot listing is modestly smaller than what the submarket average implies at the higher benchmark rate. The building holds one out of five total active listings in the York Mills submarket, representing 20 percent of current neighborhood inventory.

Hillside I's average realized lease rent of $3,620 per month sits $334 below the four-comp benchmark of $3,954, with the gap driven primarily by the outlier pricing at 10 Old York Mills. The Antiquary of York Mills (11 William Carson Cres, 0.1 km, one closed lease) averaged $3,450 per month at $3.93 per square foot across 878 square feet, meaning Hillside I's realized rent runs $170 higher than that comp. Hillside II (28 William Carson Cres, 0.15 km, three closed leases) averaged $3,633 per month at $3.50 per square foot over 1,040 square feet, placing Hillside I's rent just $13 lower. Hillside III (38 William Carson Cres, 0.15 km, three closed leases) averaged $3,533 per month at $3.21 per square foot across 1,100 square feet, so Hillside I's rent is $87 higher. 10 Old York Mills (10 Old York Mills Rd, 0.62 km, one closed lease) averaged $5,200 per month at $3.94 per square foot over 1,320 square feet, a segment where Hillside I's rent is $1,580 lower.

Hillside I leases at $3.29 per square foot across an average 1,113-square-foot suite, trading below the four-comp average of $3.65 per square foot while offering more interior space than three of the four nearby alternatives. Against The Antiquary of York Mills, Hillside I trades at a $0.64 per square foot (16.3 percent) discount while providing 235 more interior square feet; the $170 higher nominal rent is entirely a function of the larger footprint, not a rate premium. Versus Hillside II, the subject offers a $0.21 per square foot (6.0 percent) discount and 73 additional square feet, with the $13 lower monthly rent reflecting both the lower per-square-foot rate and the slightly larger unit. Against Hillside III, Hillside I commands a $0.08 per square foot (2.5 percent) premium and provides 13 more square feet, so the $87 higher rent is supported by both a modest rate advantage and marginally greater space. Compared with 10 Old York Mills, the subject trades at a $0.65 per square foot (16.5 percent) discount and provides 207 fewer interior square feet; the $1,580 lower rent is driven by both the smaller suite and the lower rate per square foot, making it a fundamentally different product tier rather than a direct like-for-like alternative.

Hillside I offers a nine-item amenity package anchored by an indoor pool, sauna and steam room, gym, media and theatre room, games and billiards room, meeting room, party and lounge room, concierge and security, and a garden courtyard—positioning it as a full-service lifestyle building within its immediate peer set. The subject's indoor pool is a genuine differentiator against 10 Old York Mills, which substitutes an outdoor pool, and its media and theatre room is absent from The Antiquary of York Mills, Hillside II, and Hillside III, none of which list that facility. Conversely, three of the four competitors (The Antiquary, Hillside II, and Hillside III) include a hot tub and jacuzzi that Hillside I does not offer, and Hillside II adds EV charging, a dining room and kitchen, a rooftop terrace, and package service. The Antiquary of York Mills differentiates with a pet wash station and rooftop terrace, while Hillside III provides an outdoor putting green and dining room. This amenity mix—indoor aquatic facilities paired with a dedicated media and theatre room but without hot tub, rooftop terrace, or pet-specific infrastructure—best serves mid-career professionals and small households in the York Mills submarket who prioritize private indoor recreation and social gathering space over outdoor leisure or pet-oriented amenities.
