A historic mill stay in Carleton Place.
Tri Century Mill Suites occupies a limestone mill built along the Mississippi River in the 1800s, on McArthur Island in the middle of Carleton Place, Ontario. It expanded throughout the 1900s and was restored in the 2000s. Now, the family-owned mill welcomes you for both short- and long-term stays.
Your serene retreat along the banks of the Mississippi River.
The walls tell you which century you're standing in. Limestone from the original mill runs through some suites, brick from the industrial years through others, and the timber beams overhead have outlasted both. River light streams through windows that were rebuilt to match what was there before. No two suites are alike since each was fitted into the mill as it stood.
A landmark shaped across three eras.
Luxurious bedding, premium linens, and modern bathrooms come standard across the suites. Layouts run from studios to one-bedroom suites, several with high ceilings and a comfortable sleeper sofa in the living area. All suites are intentionally TV-free, giving you a quieter place to unwind, though the front desk can help arrange a TV during your stay if available. Tri Century Mill Suites also keeps the practical details simple, with coin-operated laundry, convenient onsite parking, and dog-friendly suites that make it easy to bring your four-legged family members along.
Each suite has a fully equipped kitchen or kitchenette, giving you the option to stay in and whip up your own meals when you don't feel like venturing out. An onsite coffee bar and lounge is also coming soon, giving you a welcoming place to relax, connect, and enjoy a great cup of coffee. Beyond the property, downtown Carleton Place sits a few minutes' walk off the island and offers sit-down restaurants, cozy cafés, and locally sourced menus. Ottawa is also a short drive away when the occasion calls for a bigger night out.
Located on McArthur Island in Carleton Place, Ontario, within walking distance of downtown and a short drive from Ottawa.
