The 664 Spadina — Rental Market Data

The 664 Spadina has two active listings as of August 31, 2026, spanning a price range of $2,695 to $3,545 per month with an average and median asking rent of $3,120. The average active suite measures 622 square feet at an asking rate of $5.03 per square foot. Inventory is split evenly between one one-bedroom and one two-bedroom unit, placing the building squarely in the compact entry-level to mid-tier segment rather than the multi-bedroom executive tier.

The dominant active layout at The 664 Spadina is the one-bedroom tier, with one unit representing 50 percent of available inventory at an average asking rent of $2,695 per month across 527 square feet and a rate of $5.11 per square foot. The two-bedroom tier mirrors this share with one listing at $3,545 per month, 716 square feet, and $4.95 per square foot. Both tiers are single-listing samples, so no tier offers renters a meaningful selection of comparable units.

The 664 Spadina's active asking rents range from a minimum of $2,695 to a peak of $3,545 per month, producing an $850 spread or 31.5 percent differential. The median asking rent sits at $3,120 per month. The entry-level suite is a one-bedroom at 527 square feet priced at $5.11 per square foot, while the peak listing is a two-bedroom at 716 square feet carrying a rate of $4.95 per square foot.

Den premiums and square-footage deltas for The 664 Spadina cannot be quantified from the current active sample, as no paired den versus non-den listings exist in the two available units. Active parking stall costs also cannot be reliably isolated; the tracking data flags the parking premium as an unreliable outlier or insufficient sample, so no specific monthly figure can be quoted with confidence.

The 664 Spadina's active asking rate of $5.03 per square foot exceeds the The Annex submarket asking benchmark of $4.63 per square foot by 8.6 percent, while the average monthly ask of $3,120 sits marginally below the submarket average of $3,140. This nominal rent gap is fully explained by suite size: active units average 622 square feet, which is 56 square feet smaller than the submarket implied average of 678 square feet. The building accounts for two out of 14 available listings in The Annex, or roughly 14 percent of current submarket inventory.

The 664 Spadina's average realized lease rent of $5,263 per month sits $2,663 above the overall comp benchmark of $2,600 and $1,150 above the Annex submarket average of $3,113. Among active competitors, 720 Spadina Co-Ownership at 720 Spadina Avenue (0.23 km, one closed lease) averaged $2,500 per month at $2.94 per square foot across 850 square feet, placing the subject $2,763 higher in nominal rent. Mosaic at 736 Spadina Avenue (0.26 km, five closed leases) averaged $2,699 per month at $4.16 per square foot across 655 square feet, making the subject $2,564 higher in realized rent. Sussex Square at 666 Spadina Avenue (0.06 km) and Brunswick Lofts at 225 Brunswick Avenue (0.31 km) each recorded zero closed leases over the trailing 180 days, so neither provides a realized rent benchmark against which to measure the subject's pricing.

The 664 Spadina commands a premium of $4.77 per square foot on its 1,075-square-foot leased suites, exceeding both active nearby alternatives and the $3.55 per-square-foot comp average. Against 720 Spadina Co-Ownership, the subject trades at a $1.83-per-square-foot (62.2 percent) premium while providing 225 more interior square feet, so the higher monthly rent of $2,763 is amplified by a materially larger footprint rather than a pure rate increase. Against Mosaic, the subject commands a $0.61-per-square-foot (14.7 percent) premium and delivers 420 more square feet, meaning the $2,564 nominal rent gap is largely a function of the subject's expanded interior envelope. In both cases the renter trade-off is clear: paying more per month buys significantly more living area, and the per-square-foot premium over Mosaic—Toronto's closest active competitor in this pocket—remains moderate at under 15 percent.

The 664 Spadina offers a ten-feature lifestyle package including concierge and security, an EV charging station, a gym and fitness centre, a party and lounge room, a dedicated meeting room, a media and theatre room, a games and billiards room, an outdoor children's playground, a bistro, and a shared laundry room. Compared with Mosaic (0.26 km), the subject adds EV charging, an outdoor children's playground, and a bistro, while Mosaic counters with a yoga studio, rooftop terrace, BBQ area, garden and courtyard, and a dining room and kitchen that the subject does not include. Against 720 Spadina Co-Ownership (0.23 km), the subject provides concierge security, EV charging, a meeting room, a media room, a games room, an outdoor playground, and a bistro—features absent from that 1972 tower—which in turn offers an outdoor pool, sauna and steam room, rooftop terrace, and library that the 664 Spadina does not. Sussex Square (0.06 km) and Brunswick Lofts (0.31 km) recorded zero closed leases and serve only as amenity references; Sussex Square adds a library and indoor kids' play room, while Brunswick Lofts provides just a BBQ area and garden courtyard. The 664 Spadina's package—professional meeting space, EV infrastructure, a bistro, and outdoor family play—best serves dual-income professionals and young families in The Annex who prioritize work-from-home flexibility, vehicle electrification, and on-site social programming over resort-style aquatic or rooftop amenities.
