What Do You Need Permission For?

The landscape

Aquaculture in Ontario is regulated at three levels - federal, provincial, and municipal - each with its own agencies and requirements ^[1]. The good news: for a small indoor operation selling direct-to-consumer within Ontario, several of the heavier regulatory requirements don't apply.

Here's every approval you need, sorted by level and whether it's required, likely required, or exempt for our scenario (small-scale indoor biofloc, selling fresh shrimp DTC and to restaurants within Ontario).

Provincial - Farming

Aquaculture Licence Required

Issued by the Ministry of Natural Resources (MNR) under the Fish and Wildlife Conservation Act. Required for anyone culturing fish (including crustaceans) in Ontario ^{[1] [2]}.

This licence authorizes you to culture, purchase, sell, and transport eligible aquatic species. The licence conditions focus on preventing ecological damage - unauthorized introduction of species, spread of invasive species, parasites, and diseases ^[2].

Application process:

1. Review applicable aquaculture policies on ontario.ca
2. Submit application via the Natural Resources Information Portal, or download form and mail to your local MNR work centre
3. Include supporting documentation (facility plans, species to be cultured, water source details)

The application form is available from the Central Forms Repository ^[3].

Permit to Take Water Likely exempt

Issued by the Ministry of Environment, Conservation and Parks (MECP). Required for operations taking more than 50,000 litres per day from any water source ^[4].

A small biofloc/RAS system recirculates water extensively - that's the whole point. An 8-pool system holds roughly 128,000 litres total, but daily water replacement in a well-managed RAS is typically 5-10% of system volume. At 10%, that's 12,800 litres/day - well under the 50,000L threshold.

Environmental Compliance Approval (ECA) Likely required

Required for any "sewage works" including industrial wastewater treatment and discharge, under the Ontario Water Resources Act ^[5].

Your operation will generate wastewater from periodic water changes, biofloc solids removal, and pool cleaning. If this goes into municipal sewer, the municipality's sewer use bylaw applies. If it discharges to the environment (even via septic or drainage), an ECA is likely required.

The ECA process includes submitting facility plans, demonstrating effluent quality, and ongoing monitoring/reporting ^[5].

Nutrient Management May apply

Land-based aquaculture facilities may require a nutrient management strategy (NMS) or plan (NMP), depending on the operation's nutrient output and location ^[4]. Relevance depends on how you handle waste solids - if they go to sewer or licensed waste hauler, this likely doesn't apply.

Provincial - Selling

Provincial Fish Processing Licence Exempt for DTC

Issued by OMAFRA under the Food Safety and Quality Act. Required for anyone processing or packaging fish products for other than direct distribution to consumers ^[6].

Key exemption: "No provincial licence needed if all your fish products are processed or packaged for direct distribution to consumers" ^[6].

"Processing" includes: boning, coating, cooking, freezing, smoking, and other preparation activities ^[6].

If the licence is eventually needed, the application process involves 5 steps: email inquiry, submit package (business profile, product list, facility layout, water testing, food safety training docs), technical review, pre-licensing inspection, and final inspection. Contact: [email protected] ^[6].

Federal

CFIA Safe Food for Canadians Licence Exempt for intra-provincial

Required for manufacturing, processing, or packaging food for export or interprovincial trade ^[7].

Key exemption: "You do not need a licence to manufacture, process, treat, preserve, grade, package or label food that will be sold and consumed within your province" ^[7].

Additional exemption: "You do not need a licence to manufacture, process, treat, preserve, grade, package, or label food at retail if you sell the food directly to consumers" ^[7].

Fisheries Act Compliance Required

Fisheries and Oceans Canada (DFO) administers the Fisheries Act, including Aquaculture Activities Regulations. These set federal baseline requirements for aquaculture operations, including reporting of escapes (within 12 hours of discovery) and protection of fish habitat ^[8].

For a fully enclosed indoor operation with no connection to natural waterways, the practical burden is low - but compliance is mandatory.

Municipal

Zoning and Land Use Location-dependent

This is the biggest unknown and the most likely blocker.

In Ontario's prime agricultural areas, aquaculture is explicitly classified as an agricultural use ^[9]. In an agricultural zone (rural property, farm building), you're likely permitted by right.

In urban/industrial zones (Toronto, GTA), it depends entirely on the specific municipality's zoning bylaw. Indoor aquaculture could potentially fit under:

• Light industrial / employment zones - as food production or manufacturing
• Commercial zones - if combined with retail (farm gate sales)
• Agricultural zones - if available in the municipality

Toronto's Zoning By-law 569-2013 governs most properties ^[10]. Indoor aquaculture is not explicitly listed as a permitted use in any zone category. This means you'd likely need either:

• A location zoned for food manufacturing or processing
• A minor variance or rezoning application
• A location outside Toronto (Brampton, Mississauga, Hamilton) with more permissive industrial zoning

Building Permit Required

Required for constructing or renovating a building for aquaculture. Must comply with Ontario's Building Code and Electrical Safety Code ^[11].

For farm buildings under 600 m2 (~6,500 sq ft) with low human occupancy, simplified design rules apply (MMAH Supplementary Standard SB-11) ^[11]. An 8-pool operation needs ~3,700 sq ft, so it qualifies.

If converting an existing commercial/industrial space, the permit covers the change of use and any required upgrades (ventilation, drainage, electrical capacity).

Business Licence Likely required

Most municipalities require a business licence for food-related operations. Requirements and fees vary by municipality.

Food Premises Inspection Required

If you're processing or packaging shrimp on-site (even for DTC sales), your facility is a "food premises" under Ontario Regulation 493/17 ^[12]. Your local Public Health Unit will inspect for sanitation, equipment, food handling, and record keeping. At least one person on-site must have completed food handler certification (valid 5 years) ^[12].

Most food premises are inspected 1-2 times per year on a routine basis ^[12].

Summary checklist

The path of least resistance

For a small pilot (3 pools, DTC/restaurant sales within Ontario):

1. Find a location first. Zoning is the gatekeeping decision. An agricultural-zoned property in a rural municipality near the GTA (Aylmer worked for Planet Shrimp) avoids the urban zoning question entirely. An industrial unit in Brampton or Hamilton may work with the right zone. Toronto itself is harder.
2. Apply for the aquaculture licence early. Timeline is unknown, so don't wait. Contact your local MNR work centre to understand the process and expected wait.
3. Confirm water/sewer with the municipality. If your location is on municipal services, check the sewer use bylaw for discharge limits. This determines whether you need a full ECA.
4. Get food handler certification. Quick and low-cost. Do this early.
5. Register with your local Public Health Unit as a food premises before selling.
6. Skip the OMAFRA fish processing licence and CFIA licence as long as you sell direct-to-consumer and to restaurants (not through retail distribution).
