Docks, boathouses and shore walls on Lake Simcoe: permits

A dock on Lake Simcoe faces long stretches of open water, wind-driven waves and spring ice. Sooner or later, every dock, boathouse and shore wall needs repair or replacement, and every project runs into the same question. Who has to sign off?

The short version: on most of the Simcoe shore in Barrie, Oro-Medonte and Ramara, it's the LSRCA, then your township, with federal fisheries and navigation conditions you meet yourself. In Orillia, the Ministry of Natural Resources takes the LSRCA's place for erosion control work. The land-side rules behind all this are on Lake Simcoe shoreline rules.

Does Parks Canada issue permits on Lake Simcoe?

This is where a lot of people get tripped up, because Lake Simcoe is part of the Trent-Severn system and Parks Canada manages its water level. But Parks Canada's in-water and shoreline works policy lists the waterbodies under its jurisdiction, and Lake Simcoe and Lake Couchiching are not on it. What is on it: the channel between Talbot Dam and Lake Simcoe, and the channel between Lake Couchiching and the Severn River.

So for an open-lake property in Shanty Bay, Hawkestone or Brechin, Parks Canada isn't the permitting agency. If you are on or near one of those connecting channels, call Parks Canada's Trent-Severn permits office before you assume anything. Where Parks Canada does have jurisdiction, its rules are strict (no grandfathering, set dock lengths), and rossmanteam.com covers that process in its Parks Canada permits guide.

Who approves what, by municipality?

Your property is in	Land-side and shoreline approval	Building permit	Federal steps
Barrie (Kempenfelt Bay)	LSRCA permit in regulated areas	City of Barrie	DFO code or review; Transport Canada minor works criteria
Oro-Medonte (Shanty Bay to Hawkestone)	LSRCA permit in regulated areas	Township of Oro-Medonte	Same
Ramara (Lake Simcoe shore)	LSRCA permit; Ramara also says MNR issues shoreline work permits along the shore	Township of Ramara	Same
Ramara (Lagoon City canals)	LSRCA; canal shorewalls also follow a Township shorewall by-law (see Lagoon City)	Township of Ramara	Same
Orillia (Atherley end)	No LSRCA; MNR work permit for erosion control structures	City of Orillia	Same

Ramara's building page puts it plainly: in the LSRCA regulated area you must get the LSRCA permit before applying for a building permit, and if your shoreline work meets the ministry's criteria, the MNR shore land work permit also comes first.

What does the township want?

Each municipality sets its own zoning limits for structures at the water. Some concrete examples:

• Ramara lists building a deck, shed, boathouse or retaining wall, and shorewalls, as work that needs a building permit. Docks aren't named on that page, so ask building services at 705-484-5374 ext. 296.
• Oro-Medonte's current zoning by-law caps a boathouse and deck at 70 square metres combined in the Shoreline Residential zone. A 2025 minor variance application on Woodland Drive asked for 80.2 square metres, which shows how those limits get tested. The township is rewriting its zoning by-law, so check the current text.
• Barrie and Orillia apply their own zoning by-laws. Call the building department with the address before you design anything.

When does the Ministry of Natural Resources come in?

The ministry's work permits apply to shore lands that are Crown land or close to it. The key thresholds from Ontario's guidance:

• A dock or boathouse may need a permit if it is in physical contact with more than 15 square metres of shore lands. Floating sections don't count as contact.
• Building a new breakwall, revetment or groyne, or changing an existing one's dimensions, may need a permit. Repairing or replacing one usually doesn't, as long as you notify the ministry first.
• The Lake Simcoe exception: if the property is in the Lake Simcoe watershed but outside LSRCA jurisdiction (the City of Orillia), a work permit is required to build, change, maintain, repair or replace an erosion control structure.
• Dredging or filling shore lands may need a permit.

The ministry issues approved work permits free of charge, though you pay for any studies.

What do the federal rules require?

You usually don't apply to Ottawa for a private dock, but you do have to meet conditions.

Fisheries and Oceans Canada. DFO's code of practice for residential docks, boathouses and moorings covers structures that float or sit on pipes, piles, poles, anchors, blocks or cantilevers. It excludes new crib docks, foam floats, fill, dredging and excavation below the high-water mark. If you follow the code, you send DFO a notification at least 10 working days before starting. If your project doesn't fit the code, you request a DFO review instead.

Transport Canada. Lake Simcoe is a scheduled water under the Canadian Navigable Waters Act. A dock or boathouse that meets the Minor Works Order criteria can proceed without applying for approval:

Criterion	Requirement
Distance from property lines and their extensions	5 m or more
Distance from other people's works in the water	More than 10 m
Distance from a navigation channel	30 m or more
Length into the water	No longer than similar docks within 100 m on the same shore (max 50 m), otherwise 30 m
Width of waterway occupied	No more than one-third
Float planes	Not allowed

Lake Simcoe is a charted water (Canadian Hydrographic Service chart 2028 covers Lakes Simcoe and Couchiching), so you must notify the Canadian Coast Guard's Marine Communications and Traffic Services in writing at least 48 hours before work begins. Erosion protection that juts more than 5 metres into the water isn't a minor work, and minor erosion protection also needs a registry deposit and public notice.

When can the work happen?

In-water work has to avoid fish spawning periods. DFO's Southern Ontario windows (dates to avoid) include March 15 to May 31 for walleye and northern pike, May 1 to July 15 for bass, and October 1 to May 31 for lake trout. The windows that apply depend on the species at your site, and the ministry sets timing guidance case by case, so your LSRCA or MNR permit is where you'll find the dates that bind you.

What should a buyer ask about existing docks and boathouses?

• Is there an LSRCA permit, township building permit, or MNR work permit for each structure? Get copies, not descriptions.
• Was the boathouse ever used as sleeping space? The Plan doesn't allow structures in the lake intended as dwellings.
• Is the dock or boathouse on the owner's land, or on an unclosed shore road allowance? rossmanteam.com's shore road allowance guide explains how to tell.
• How has it handled ice? Ask about repairs after recent winters. See ice fishing and winter.

An unpermitted structure isn't automatically a deal-breaker, but the LSRCA's 2026 fee schedule lists retroactive permits at "25% of original fee; up to 3× fee with non-compliance," and approval isn't guaranteed. Price that in.

How Jordan can help

Jordan can help you gather the permit history for every structure on a Lake Simcoe listing before you commit, and flag the ones that need answers from the LSRCA, the township or the ministry. If you are selling, he can help you pull those records together early so they support your price.
