Environmental, equipment and union issues in a manufacturing sale

A manufacturing sale carries three legal issues that catch people off guard more than any other: environmental conditions tied to the property’s industrial history, the tax consequence of selling depreciated equipment, and whether a union agreement continues to bind the business under new ownership. Each depends on deal structure and provincial rules, and each is worth resolving before a purchase agreement is signed.

Reviewed

Manufacturing sales carry legal complexity that most small business sales do not, because the physical plant itself — the land, the equipment, sometimes a unionized workforce — brings obligations that follow the business rather than staying with whoever owned it when the problem was created. Two issues in particular surprise sellers more than anything else in this sector: what the property’s industrial history means for environmental liability, and what selling depreciated equipment does to the seller’s tax bill. A third, union successor rights, surprises buyers just as often. None of the three is exotic once understood, but all three need to be addressed before closing, not discovered after. A buyer or seller who understands all three well before a purchase agreement is drafted is in a far stronger position to negotiate terms that reflect the actual risk, rather than discovering the scope of any one of them mid-transaction.

Environmental liability follows the property, and sometimes the entity

Land with a manufacturing or industrial past can carry contamination in the soil or groundwater that has nothing to do with anything the current owner did, and that exposure does not automatically go away just because the business changes hands. How much of it a buyer inherits depends heavily on deal structure: an asset purchase can sometimes be arranged so certain historical environmental liabilities stay with the selling corporation, while a share purchase generally carries the whole entity forward, contamination history included. An environmental site assessment, commissioned early enough to actually inform the deal, is the standard way both sides get a factual picture instead of relying on assumptions.

CCA recapture turns a capital gain into income

When equipment is sold for more than its remaining value for tax purposes, the difference between that value and the lower of cost or sale price can be recaptured and taxed as income rather than as a capital gain — a mechanism tied to how capital cost allowance works under Canadian tax rules. This is the second issue that regularly surprises sellers, because it can turn what felt like a straightforward equipment sale into a larger-than-expected tax bill in the year of sale, and it factors directly into how a seller compares an asset sale against a share sale for a given transaction. The specific numbers depend on the equipment involved and belong with an accountant, not a general estimate.

Transferring the equipment itself

Beyond the tax treatment, the mechanics of an equipment transfer need attention: confirming which units are financed or leased and require lender or lessor consent to transfer, checking for any liens registered against specific machines, and documenting condition at the point of transfer so there is no dispute later about what was actually delivered. None of this is complicated in isolation, but skipping it is a common way a closing gets delayed at the last moment over a piece of paperwork nobody thought to chase down earlier. Where equipment was purchased used or imported, confirm there is a clean paper trail establishing ownership, since a buyer’s lender will generally require this before advancing funds against it as collateral.

What happens to a collective agreement

If the plant’s workforce is unionized, the collective agreement generally continues to bind the business when a buyer carries on substantially the same operation, particularly in an asset purchase — this is the general principle of successor employer obligations in Canadian labour law. Labour law in Canada is set provincially for most sectors, and federally for industries that fall under federal jurisdiction, so the specific rules, and how they apply to a given transaction, depend on where the business operates and what sector it is in. A buyer who assumes a union agreement simply lapses with a change of ownership is working from a wrong assumption more often than a right one.

Why these three issues interact

Environmental exposure, CCA recapture and union successor obligations are often discussed separately, but they influence the same underlying decision: how the deal gets structured. A seller weighing an asset sale against a share sale is not just comparing headline tax outcomes — they are also weighing who keeps historical environmental exposure, how the collective agreement is treated, and which structure a buyer’s lender will actually finance. Working through all three together, rather than one at a time, tends to produce a structure that holds up rather than one that creates a new problem to solve the old one. A buyer’s lender is often weighing the same three factors independently when deciding how much to advance and on what terms, which is one more reason to have clear answers before financing conversations begin in earnest.

Getting ahead of it

Sellers who commission an environmental assessment, get a tax projection on equipment recapture, and pull the current collective agreement before going to market are not just avoiding surprises — they are giving buyers the confidence to move faster, because uncertainty on any of these three fronts is exactly what makes a cautious buyer slow down or ask for a lower price to cover the unknown.
