Innisfil holds the west shore of Lake Simcoe from Gilford at the bottom of Cook’s Bay north through Lefroy, Belle Ewart, Alcona and Sandy Cove to Big Bay Point, the headland that separates Cook’s Bay from Kempenfelt Bay. It is the one Lake Simcoe municipality that writes waterfront rules into its own zoning: lakefront lots carry a W suffix requiring a 15-metre setback from the shoreline, 30 metres where the lot is deeper than 60 metres, with half the waterfront yard kept naturalised and boathouses capped at 10 metres of projection. The Lake Simcoe Protection Plan’s 100-metre septic rules apply and the Town inspects septics every five years for $142. Innisfil chose not to license short-term rentals in 2022 and instead allows only owner-occupied bed and breakfasts. Friday Harbour is a resort with a 1,000-slip marina whose occupancy restrictions were lifted in 2020. The promised Innisfil GO station has no construction date. TRREB’s August 2026 table shows an average sale of $741,394 and 7.4 months of inventory.
The shore from Gilford to Big Bay Point
Innisfil’s 2021 population was 43,326 across 262 square kilometres, with Highway 400 through its west side and Lake Simcoe along its east. The shoreline communities run south to north: Gilford at the head of Cook’s Bay, then Lefroy and Belle Ewart, Alcona, the Town’s largest lakeside community with Innisfil Beach Park, Sandy Cove, and finally Big Bay Point, the peninsula where the Friday Harbour resort sits. Cook’s Bay is shallow and plant-rich, which affects the southern communities most; Big Bay Point looks across to Kempenfelt Bay, the deepest part of the lake. The conservation authority flags Innisfil’s shore for storm surge under sustained easterly winds and lower Cook’s Bay for high-water flooding. Innisfil Beach Park covers 27.6 hectares with a boat launch, dock and beach zones, and the health unit tests three beaches, Innisfil Beach Park, 9th Line and Leonard’s Beach, weekly from June to Labour Day.
Waterfront rules written into the zoning
Most municipalities leave the shoreline to the conservation authority. Innisfil’s Comprehensive Zoning By-law 080-13, adopted in 2013 and consolidated to January 2025, adds its own layer with a W suffix on waterfront lots under section 3.51. The minimum waterfront yard setback is 15 metres or the existing setback, whichever is greater, and where the lot is deeper than 60 metres it becomes 30 metres from Lake Simcoe. At least half of the waterfront yard must stay as naturalised vegetation, the front yard is capped between 4.5 and 7 metres so houses sit toward the road, the principal building may be no longer than 19 metres, and only one accessory building related to shoreline recreation, a boathouse, sleeping cabin or shed, may sit in the waterfront yard.
Section 3.10 governs boathouses and docks: no human habitation, a five-metre height limit, a total width of no more than 25 percent of the frontage or 12 metres, whichever is less, and no more than 10 metres of length or of projection into the water. Layer the conservation authority’s 30-metre setback for new development on top and the buildable envelope on a shallow lot can be smaller than the house standing on it. Read teardown or renovate on a lakefront lot; the order of asking is the same here.
Septic, sewer and the Lakeshore plant
The Lake Simcoe Protection Plan’s 100-metre rules apply across Innisfil’s shore: no new septic within 100 metres of the lake and a mandatory re-inspection zone. Innisfil’s program inspects every property within 100 metres of the shoreline, a municipal well or a watershed river, stream or pond once every five years, and charges $142 for the standard visual inspection, waivable for advanced treatment units on a maintenance contract. The zoning by-law also bars an accessory dwelling unit on any septic lot within 100 metres of the lake.
Municipal sewer is available where the Lakeshore Wastewater Treatment Plant reaches: its 2025 annual report lists Sandy Cove, Alcona, Belle Ewart, Friday Harbour and Lefroy, with a rated capacity of 17,000 cubic metres a day and an expansion to 25,000 that began construction in 2025 specifically to meet the phosphorus limits for discharge into Lake Simcoe. Whether Gilford and the Big Bay Point lots outside the resort are on sewer or septic is not something the public documents settle; ask the Town for the specific address. Drinking water for the lakeshore communities comes from the Alcona-Lakeshore surface water plant.
Friday Harbour: a resort inside a town
Big Bay Point has been a resort destination since the Peninsular Park Hotel opened in July 1887, built in four months with sixty rooms and reached by steamer from Barrie; it burned in 1955, and the Big Bay Point Golf Club dates from 1924. Friday Harbour is the modern version: first proposed in 2002, approved by the Ontario Municipal Board in 2007, under construction from 2011, with first residents in 2017 and phase one complete in 2018. It covers about 600 acres with a 1,000-slip inland marina described as the largest of its kind in Canada, a plan for 2,600 residential units and a 400-room hotel, an 18-hole course and a nature preserve.
Two facts matter to a buyer. In October 2020 the Town amended the Big Bay Point Resort Secondary Plan to remove occupancy restrictions, so units can be lived in year-round. And the hotel has been moving: a 2021 application sought a six-storey, minimum 200-room hotel on the Big Bay Point Road lands, and in August 2022 the developer asked to delay the hotel in favour of a retirement residence. The most recent proposals were reported in local news I could not verify, so treat the hotel’s status as open. A Friday Harbour condominium is a resort condominium with resort fees and rules, and it is not the same asset as a freehold lot on the Innisfil shore.
Short-term rentals: no licence, and no whole-home rentals
On 22 June 2022, after two years of consultation, Innisfil Council decided not to pass a short-term rental licensing by-law and instead tightened its land-use rules. Zoning defines a short-term accommodation as a whole dwelling unit rented for fewer than 28 consecutive days, permits only bed and breakfasts of up to three guest rooms owned and operated by a person living on the premises, and the noise by-law was amended so staff can charge operators for guests’ conduct. A cottage marketed as an investment rental in Innisfil is being marketed against the by-law. Ask the Town before you rely on rental income.
The station that is not there
Highway 400 runs through the west of the Town and the Bradford Bypass, under major construction since 14 May 2026 with no opening date, will start at the 400 just south of Innisfil. Rail is the harder story. Innisfil has been promised a GO station at 6th Line, the centre of the Orbit development, since Council picked the site in 2016; a Minister’s Zoning Order was issued in 2020, the developers submitted a 90 percent design to Metrolinx in 2025, and Metrolinx has given no construction timing because the station depends on private financing. The Town says the transit hub will be funded by the development community and not by taxpayers. Until it exists, Innisfil commuters use Barrie South GO, open since 2007 with 623 parking spaces, or Bradford GO, 67 kilometres from Union. Price the lot on today’s station, not the promised one.
Taxes, beaches and algae
The Town’s combined 2026 residential rate is 1.239628 percent, covering Town, Simcoe County and education, after Council adopted 5.5 percent increases for both 2025 and 2026. Assessments remain on January 2016 values. The health unit’s beach season runs from late June to Labour Day with weekly sampling and a 200 E. coli per 100 millilitres threshold; the conservation authority notes blue-green algae blooms are commonly found near docks and shorelines in late summer, and the Town has posted confirmed-bloom notices in past years. Swimming in front of your own dock is a question for the health unit’s postings, not the listing.
What TRREB shows
TRREB reports Innisfil within its Simcoe County tables. August 2026: 54 sales at an average of $741,394 and a median of $751,500, 189 new listings, 431 active listings and 7.4 months of inventory on the trend, the deepest inventory of any market in this series. Detached houses accounted for 44 of the sales at an average of $795,975 and a median of $806,500; six condominium apartments averaged $452,165. The HPI composite benchmark was $666,400, down 7.51 percent year over year. The quarterly community report for April to June 2026 shows Alcona with 77 sales at $780,379 average and $800,000 median, Lefroy 15 at $765,207, Gilford 7 at $846,714, and Rural Innisfil, the row that contains Big Bay Point and Friday Harbour because TRREB has no separate community for them, 71 sales at $893,746 average and $850,000 median with detached houses averaging about $976,000.
As everywhere in this series, these are whole-community numbers. Innisfil’s waterfront lots and the resort condominiums sit inside averages dominated by the subdivisions behind them. Deep inventory and a falling benchmark mean a buyer here has time and leverage; a seller needs the file described in what buyers will ask for more than ever.
The takeaway
Innisfil is the Lake Simcoe shore with the most explicit rules: a 15-to-30-metre waterfront setback and boathouse limits in the zoning itself, the Protection Plan’s 100-metre septic regime with a $142 five-year inspection, no rental licence and no whole-home short-term rentals, a resort at Big Bay Point that is its own market, and a GO station that remains a drawing. Inventory is deep. Buy the lot for what it is today and get the setback, the sewer status and the dock permits in writing.

Frequently asked questions
How far from Lake Simcoe must a new house be in Innisfil?
The zoning by-law’s W suffix requires a waterfront yard setback of at least 15 metres, or 30 metres where the lot is deeper than 60 metres, and the conservation authority requires 30 metres from the normal high-water mark for new development. The greater governs.
Can I build a boathouse in Innisfil?
Yes, within limits: no human habitation, five metres high at most, total width no more than 25 percent of the frontage or 12 metres, and no more than 10 metres of length or projection into the water. Conservation authority and Public Lands Act rules also apply.
Does Innisfil license short-term rentals?
No. Council decided on 22 June 2022 not to license them. Zoning permits only owner-occupied bed and breakfasts of up to three rooms, and whole-home rentals under 28 days are not a permitted use.
Is Friday Harbour a year-round community?
Since October 2020, yes; the Town removed the resort’s occupancy restrictions. It remains a resort condominium community with its own fees and rules, and the planned hotel’s status has changed several times.
Is there a GO station in Innisfil?
Not yet. The Innisfil GO station at 6th Line has a zoning order from 2020 and a 90 percent design from 2025 but no construction date, because it depends on private financing. Barrie South and Bradford are the nearest stations.
What does the septic inspection cost in Innisfil?
$142 for the standard five-year inspection of any property within 100 metres of the lake, a municipal well or a watershed watercourse. The fee can be waived for advanced treatment units on a maintenance contract.
What is the average house price in Innisfil?
TRREB’s August 2026 table shows 54 sales at an average of $741,394 and a median of $751,500, with 7.4 months of inventory and an HPI benchmark of $666,400. Waterfront lots trade above these community-wide figures.
