Thought for 31s
Short answer up front — partial yes for the U.S., unclear / likely no for Ontario:

U.S.: there is a public SEC Form 1-A / Regulation A offering statement for Legacy Teak, LLC (ties the offering to the Gran Pacifica teak plantation). That filing is concrete evidence the sponsor at least engaged the U.S. securities process for a Regulation A offering.

Ontario (Canada): I could not find any public OSC (Ontario Securities Commission) registration or prospectus filing for ECI Development / Gran Pacifica (nor did I find them listed as an Ontario registrant or on SEDAR+ in my searches). That means there is no obvious public record that the issuer or any Ontario selling agent was registered as an Exempt Market Dealer or filed a Canadian prospectus — which, if true in fact, suggests sales to Ontarians may have been made without the Canadian filings/registrations that provincial law normally requires.

Why those two conclusions:

Evidence of a U.S. filing (Regulation A / Form 1-A).
Legacy Teak, LLC filed an Offering Statement on EDGAR (Form 1-A) dated April 2020 describing the sale of “Interests” in a teak plantation at Gran Pacifica — with offering terms, risk factors, manager disclosure, etc. A Regulation A qualification (or a filed 1-A) is an accepted U.S. path for raising capital from U.S. investors. That filing therefore supports the proposition that the teak-as-investment product was at least presented as a U.S. securities offering and the issuer used a U.S. securities registration/exemption route.

Canadian/Ontario law that would apply (and what I looked for).

In Ontario, to sell securities to Ontario residents you generally need either a prospectus filed and receipted OR to rely on a statutory prospectus exemption (e.g., accredited-investor, offering memorandum, etc.). Dealers who sell exempt securities must typically be registered (Exempt Market Dealer) under NI 31-103. See the OSC pages on the exempt market and NI 31-103. If none of those steps were taken, the trades can breach the Securities Act (Ontario) and registration rules.

What it would mean if sales were made into Ontario without Canadian compliance

Possible breaches / actionable issues:

Distribution of securities without a receipted prospectus or valid exemption (contravention of the Securities Act and NI 45-106/31-103 framework).

Trading as an unregistered dealer (acting as an Exempt Market Dealer or dealer without registration under NI 31-103).

Misleading or fraudulent disclosure if materials omitted material facts or misrepresented returns/risk (basis for civil claims and regulator enforcement).

Solicitation across borders without complying with local rules (U.S. Reg A compliance does not exempt compliance with Canadian provincial law).
These are standard legal risks that Canadian regulators (OSC, other provincial regulators) and civil plaintiffs rely on.

Caveats / limits of my search

I found a clear U.S. SEC 1-A filing for Legacy Teak, LLC (evidence of U.S. securities paperwork). 
SEC

I did not find a public OSC enforcement action, prospectus, or registrant listing for ECI / Gran Pacifica / “Teak” offerings in Ontario via the OSC registrant pages and SEDAR+ searches I ran. That is not proof there was no compliance (the issuer may have used a private Canadian exemption, small-scale in-province filings, or there may be non-public regulatory files), but it is a red flag that warrants follow-up because selling to Ontarians usually requires either registration or a prospectus/exemption.

What I recommend (practical next steps)

If you (or others) bought these interests, collect all documents — emails, PDFs, contracts, wire receipts, the exact marketing materials used, dates, names of sales agents, and the jurisdiction where you were solicited. (This evidence is decisive.)

Compare the U.S. offering materials (Legacy Teak, LLC Form 1-A) to what you were shown — look for differences in fees, risk disclosures, minimums, related-party arrangements. I can pull specific sections from the Form 1-A on request. 
SEC

Ask an Ontario securities lawyer (or file a complaint with the OSC) if you believe you were sold securities in Ontario without proper registration/exemption — the OSC enforces registration and prospectus rules. If you’re in the U.S., you can also contact the SEC
