How do you quickly filter land deals in Ontario before doing full due diligence?

Question

Based in the GTA and trying to understand how people approach this in practice.

When you come across a potential land deal in Ontario, what’s the first thing you check to decide if it’s even worth spending more time on?

Do you have a quick way to filter deals, or do you end up digging into zoning, flood risk, conservation authority constraints, etc. each time?

Curious what your early screening process looks like — especially how you do it quickly before going too deep.

Great question Karthik, and the follow-up about quick checks is really the key issue here.

I've been investing in land for 5+ years (mostly in Texas and Utah) and here's the quick-filter workflow I use before spending any real time on a deal:

1. Zoning check first — Is the parcel zoned for what you want to build? This eliminates 40-50% of deals instantly. In Ontario you'll want to check the municipal zoning bylaw for the specific township.

2. Lot dimensions & setbacks — Even if zoning works, setbacks can kill your buildable area. A 50x100 lot with 25ft front/10ft side setbacks leaves way less buildable area than you'd think.

3. Environmental flags — Flood zones, conservation authority restrictions, wetlands. In Ontario, your local Conservation Authority (TRCA for the GTA) has mapping tools that show regulated areas. Any of these = walk away or budget for significant extra costs and delays.

4. Utilities — No municipal sewer/water access = massive cost add for wells and septic. Check with the municipality.

5. Road access & frontage — Landlocked parcels or insufficient frontage can be dealbreakers.

To answer your question about whether these can be done in a few minutes: for US deals, I actually built a platform (ReadyPermit.ai) that pulls zoning, setbacks, lot coverage, flood risk, and buildability data instantly for any US address. It started because I was spending 3-4 hours per deal doing this manually.

For Ontario specifically, you'll want to check the municipal zoning maps online, plus the Conservation Authority's mapping tools. Many Ontario municipalities have their zoning bylaws and maps available online now, which helps speed things up.

Happy to share more details on the workflow if helpful!

Hey Stephen, this is a great way to think about it. Treating those constraints as the first filter really resonates.

In your own deals, how do you usually approach that early check?

Do you treat things like zoning or permit eligibility as a hard yes or no right away, or are there cases where you still look further even if something looks off initially?

Also curious what your first couple of checks tend to be when a deal comes in. Is it usually zoning first, or does it vary by situation?

And roughly how many deals get ruled out at that stage before you spend more time on them?

That breakdown is really helpful.

Have you seen cases where something passed Tier 1 and 2 but still turned into a bad deal later?

Trying to get better at catching those early.

Hai — appreciate the shoutout. Your point about Greenbelt is exactly the kind of thing that kills deals silently. One overlay restriction can turn a "great deal" into unbuildable land overnight.

Karthik — to your question about handling unknowns early: don't wait until everything is verified. That's a trap.

My approach is a 3-tier filter:

Tier 1 (60 seconds): Zoning designation, conservation/Greenbelt overlay, and basic permitted uses. If the zoning doesn't allow what you want to do, stop here. Don't even pull comps.

Tier 2 (10 minutes): Setbacks, height limits, lot coverage maximums, environmental flags (flood zone, wetlands). This tells you what you CAN physically build on the site.

Tier 3 (deep dive, only if Tiers 1-2 pass): Full municipal pre-consultation, servicing availability, development charges, site-specific constraints.

90% of bad deals die in Tier 1 or 2. The key is being disciplined enough to actually kill them there instead of thinking "maybe I can get a variance." Those are $5K-$15K rabbit holes.

Move forward with assumptions on stuff that's verifiable later (exact development charges, timeline), but never assume on zoning or overlays. Those are binary — you either can or you can't.

That’s a really good point, especially with things like Greenbelt where one constraint can completely change what’s possible.

Out of curiosity, how do you usually handle those unknowns early on when looking at a deal? Do you wait until everything is fully verified, or move forward with some assumptions and refine as you go?

Karthik Ganesan Pillai · Answer

This is super helpful, especially the way you laid out the workflow.

The zoning eliminating 40–50% of deals really stood out to me.

Out of those steps, which one used to take you the most time before you built your platform?

Was it pulling data from different sources, or interpreting things like setbacks and zoning rules?

@Landon Reid  made a lot of great points

There are still some unknowns that you need to know that only local experts know..

Ontario has Green and White Belt.. You have to be 100% sure if it is or not.. GreenBelt you cannot build a single thing and have limitations on what to do with that land

Depending on what you plan on doing with that piece of land there are many angles you need to research..

Make sure the zoning matches what you are looking for..  and if you thinking of building a subdivision  you need to be extremely careful

Karthik Ganesan Pillai · Answer

That’s really helpful, especially the order you follow.

When you check flood zones, roads, and utilities, are those quick checks you can do in a few minutes, or do they still take a bit of digging across different sites?

Also curious, have you ever had a case where something looked fine in this early pass but turned out to be a problem later?

I used to wholesale land in Florida for home builders here. Since I filtered my leads on land size, I really dont need to worry about zoning. Most lots of that size are residental. I would check for flood zones, busy roads first. Then check the neighborhood on google maps. Then I would check for utilities and send to builder to make sure they like it. Once I get go ahead and price point, I would engage with seller.
