About this property

A magnificent waterfront retreat on Lake Ontario, 263 Niagara Boulevard pairs timeless architectural design with effortless lakeside living and grand-scale entertaining. Step inside to an immediate sense of secluded tranquility. A graceful curved staircase introduces the main level, opening to the Great Room, framed by expansive floor-to-ceiling windows capturing panoramic views of lush grounds, sweeping waters, and the Toronto skyline on the horizon. Ten-foot ceilings enhance the scale of the main-floor spaces. In the dining room, a four-panel bi-fold glass system retracts completely to unite the interior with a 3 Season Patio to continue the sweeping waterfront views. Alongside, a chef-inspired kitchen-crowned by a central skylight-serves as an intimate family hub or a full-scale catering staging area. The main-floor primary retreat offers a private sanctuary overlooking the water, featuring a walkout to a covered lakeside patio, an expansive dressing room, and a spa-inspired ensuite. A second main-floor bedroom with ensuite, mudroom, and laundry complete the main level. Upstairs, nine-foot ceilings frame two secondary bedroom suites, each with water views and their own private balcony. A versatile studio or executive office opens to a balcony overlooking the adjacent parkette. Discretion and peace of mind are engineered into the layout, featuring a dedicated service entrance from the garage to bypass personal living quarters. Positioned on an expansive parcel, the property offers rare flexibility to retain the estate in its current majestic form or capitalize on an approved severance. The location, size, and architectural caliber rank this home as one of the premier lakefront legacy properties. in Niagara-on-theLake
