Drainage System

May 30, 2025


What are Drainage Systems?

A drainage system refers to the infrastructure and design features that remove excess water from a property to prevent flooding, water damage, and structural deterioration.

Why Do Drainage Systems Matter in Real Estate?

In Canadian real estate, proper drainage is essential for protecting a property’s foundation, basement, and surrounding land from water infiltration.



Drainage systems may include:
  • Eavestroughs and downspouts
  • French drains and weeping tiles
  • Grading and swales
  • Sump pumps and catch basins



Inadequate drainage can lead to basement flooding, mold, and expensive repairs. Many home inspections assess drainage effectiveness, especially in older homes or high-precipitation regions.



Understanding drainage systems helps homeowners maintain their property and identify potential red flags when buying real estate.

Example of Drainage Systems in Action

A home’s grading slopes away from the foundation and includes downspouts that extend two metres, forming part of an effective drainage system.

Key Takeaways

  • Prevents water damage and erosion.
  • Includes gutters, grading, and sump systems.
  • Essential for foundation integrity.
  • Evaluated during inspections.
  • Impacts home insurance and resale value.

Hale Muskoka Is Going All-Season With Multi-Pronged Expansion

Hale Muskoka Is Going All-Season With Multi-Pronged Expansion
Hale Muskoka at 1160 Bethune Drive North/Hale Corporation

On any given weekend from summer through early fall, Hale Muskoka has something unique to do, eat, and see. You might find yourself building a charcuterie board under the watch of Michelin-recognized chefs, grabbing a bite from a food truck to enjoy at the fireside lounge, or perusing the open-air market with live music as your soundtrack. And that’s only a small taste of what Hale currently is — and what Founder Eric Abugov wants it to be.

“It's built for you to experience,” says Abugov, a development sector veteran who soft-launched the market and events hub with his wife last summer. Today, locals, cottagers, and tourists can flock to their five-acre farm in Gravenhurst, home to a mix of food and retail vendors, a weekly open-air market, and a revolving door of events and activities. More than that, Hale offers the benefits of a “third space” — something Abugov and his wife felt was missing after moving to the area post-pandemic.

Throughout history there have been many famous portmanteaus. Combining breakfast and lunch into one meal? Brunch. Getting angry because you’re hungry? You’re hangry. Ben Affleck and Jennifer Lopez are back together? Congrats, Bennifer.

In British Columbia, our most famous portmanteau is Burquitlam, the neighbourhood located on the Coquitlam side of the Burnaby-Coquitlam boundary. The neighbourhood is situated south of the City of Port Moody, and has become its own burgeoning neighbourhood that stands alone from the bustling Lougheed neighbourhood located immediately to the south.

Minto Pivots To Purpose-Built Rental For Five-Tower Mimico Proposal

Minto Pivots To Purpose-Built Rental For Five-Tower Mimico Proposal

Rendering of Grand Park Village in Mimico/Wallman Architects

It’s been around a decade since plans were put in motion for Grand Park Village: a multi-block, mixed-use community proposed for 2 and 10 Audley Street and 29, 31, 39, 59, and 71 Portland Street. The series of addresses are a five-minute walk from Mimico GO, which has drawn plenty of development focus in recent years. (Think: Grand Central Mimico, which was at one point on track to be Ontario’s first transit-oriented community.)

The most recent iteration of the plans come from Minto Communities and call for 42-, 54-, 52-, 39-, and 34-storey towers that would sit in a triangular cluster around an interior courtyard, the GO Transit Rail Corridor running past the south side of the site. True to its name, the community is set to be a contemporary urban village that’s not only a hub for residents, but draws in the public with new retail, daycare, roads, and parkland dedication occupying around 10% of the site.

Montreal-based Cromwell Management appears to be on a development proposal streak after filing its third major application with the City of Toronto since the spring. The latest plans are for a 45-storey mixed-use building at 525 Eglinton Avenue East, where it would be a five-minute walk from the recently-opened Leaside Station of the Eglinton Crosstown LRT.

Because of the 10-storey rental building already on the site, Cromwell’s plans call for 53 replacement rentals, in addition to 473 net new rentals, for a total of 526 units. That also breaks down into 45 bachelor units, 342 one-bedrooms, 113 two-bedrooms, and 26 three-bedrooms, with all units slated for floors two through 45.
