Key takeaways
  • An environmental site assessment is a staged review of a property's history and condition, and it is separate from a price appraisal.
  • Alberta's Corporate Registry searches can show a corporation's registration date, owners, directors and legal addresses, and Personal Property Registry searches cover items such as vehicles, trailers, aircraft and boats, but neither is described as showing whether land is contaminated, so how to check that depends on your situation and is worth confirming with a lawyer.
  • Who bears contamination risk depends on the facts and on what the purchase agreement says, so get legal advice before you sign.

If the business you want to buy owns or leases land, you are not only buying customers, equipment and a name. You may also be taking on whatever has happened on that land over the years, including spills, storage tanks, or past industrial use.

This article explains, in general terms, what environmental checks buyers usually consider in Alberta, which official records searches can help, and why contamination risk is worth raising with a lawyer before you commit.

This article covers the law of Alberta.

Why land changes the risk

Problems with soil or groundwater are often hidden. A tidy-looking shop, yard or farm site can still have a history that only shows up in records or testing. Cleanup can be costly, and it can also affect whether you can finance, insure or later resell the property.

Whether you could be responsible for contamination under Alberta law depends on the facts, including your role (owner, tenant or operator), when the problem occurred, and how the deal is structured. A lawyer can explain how that applies to your purchase.

What an environmental site assessment involves

An environmental site assessment is a review done by a qualified environmental consultant. It is usually done in stages, and each stage goes further only if the earlier one raises concerns.

An assessment is not the same as an appraisal. A valuation looks at what the property is worth. It does not tell you whether the site is clean.

Registry searches that support your checks

Registry searches do not replace an environmental assessment, but they help you confirm who you are dealing with and what interests may be attached to the business.

SearchWhat it can show
Corporate Registry current or historical searchRegistration date, owners, directors and legal addresses of current or formerly registered Alberta and extra-provincial corporations, partnerships, trade names and incorporated non-profits
Certificate of statusStatus as of a given date only; a historical certificate confirms status as of a past date
Personal Property Registry searchRegistered interests searched by business debtor name, serial number (vehicles, trailers, aircraft, boats and similar items) or registration number

Corporate Registry searches are requested through a registry agent, who charges a government fee plus a service fee. Certificates of status are not available for trade names and partnerships. Personal Property Registry searches are requested on a Search Request form at any registry agent office in Alberta.

Money and structure issues tied to land

If you plan to borrow, note that Canada Small Business Financing Program term loans can cover commercial real property. Financing is capped at the lower of the purchase price or the appraised value of the eligible assets. That appraisal figure is about value, so it is not a substitute for environmental due diligence.

Tax can also matter. Even with a valid GST election for the sale of a business, tax is still payable on a taxable sale of real property where the buyer is not a registrant. An accountant can confirm how this applies to your deal.

Contract protection is the other piece. Buyers often ask for promises from the seller about the condition of the land and for a way to recover costs if a problem appears later. Our article on holdbacks and indemnities explains how those tools generally work.

What to do next

Frequently asked questions

Do I need an environmental site assessment if the business only leases its land?

It can still be worth considering, because a tenant may have obligations under the lease and may be affected by what happens on the site. What applies depends on the lease and the facts, so have a lawyer review both before you buy.

Can a registry search tell me if land is contaminated?

No. Corporate Registry searches show details such as registration date, owners, directors and legal addresses, and Personal Property Registry searches show registered interests. Contamination is assessed through environmental records review and, where needed, testing.

Does a property appraisal cover environmental risk?

An appraisal speaks to value and is a separate exercise from an environmental assessment. Lender financing under the small business program is capped at the lower of purchase price or appraised value of the eligible assets, which does not address contamination.

Who pays for the environmental assessment?

That is usually negotiated between buyer and seller, and the buyer often arranges it. Settle it in writing early, ideally before you sign the purchase agreement.
