Of all the CRA's collection tools, a charge registered against a taxpayer's home or other real property is among the most consequential, because it can sit silently on title for years and surface only when the taxpayer tries to sell, refinance, or borrow against the property. The mechanism is sometimes loosely called a "tax lien," and it begins with a step many taxpayers never see coming: the registration of a certificate in the Federal Court of Canada. This guide explains how that certificate becomes a charge on property, what it does once registered, and the routes to dealing with it.
From assessment to certificate
A tax debt does not, by itself, attach to a taxpayer's property. The CRA must first convert the administrative debt into something enforceable as a judgment. It does this under section 223 of the Income Tax Act (with parallel provisions in the Excise Tax Act for GST/HST), which allows the Minister to certify an unpaid tax amount and register the certificate in the Federal Court. Once registered, the certificate has the same force and effect as a judgment of that court for the certified amount.
The significance of the certificate is that it transforms an unpaid assessment into a judgment debt the CRA can enforce through the ordinary machinery available to a judgment creditor. The taxpayer does not get a trial on the certificate — the underlying tax was already assessed, and the time to dispute it was through the objection and appeal process. The certificate simply makes the assessed amount enforceable as a court judgment.
How a charge attaches to real property
With a Federal Court certificate in hand, the CRA can take the further step of securing the judgment against the taxpayer's real property. The exact mechanism depends on the province in which the property is located, because land registration is a provincial matter. In broad terms, the CRA registers a memorial of the Federal Court judgment, or obtains and registers a writ of seizure and sale, in the relevant provincial land registry or personal property registry. The result is a charge — commonly called a tax lien — that binds the property.
The practical consequence is that the charge runs with the property. A taxpayer who later tries to sell will find that the charge must be addressed before clear title can pass to a buyer; a taxpayer who tries to refinance will find that a lender's solicitor turns up the charge on a title search. In effect, the CRA's claim is secured against the equity in the property, and the taxpayer cannot freely deal with that equity until the charge is dealt with.
What a tax lien does — and does not — do
A registered charge secures the debt against the property; it does not, on its own, force an immediate sale of the home. To realize on the charge the CRA would generally have to take additional enforcement steps, and a forced sale of a principal residence — while legally possible — is not the typical first move. More often the charge sits on title and is satisfied out of the proceeds whenever the taxpayer eventually sells or refinances.
That said, the charge is far from harmless while it sits there. It freezes the taxpayer's ability to use the property's equity, can complicate or block a refinancing the taxpayer needs for other purposes, and signals to lenders and others that the CRA has a secured claim. And because interest continues to accrue on the underlying debt, the amount required to clear the charge grows over time. A charge that the taxpayer ignores does not become cheaper.
Notice — or the lack of it
Taxpayers are often surprised that a certificate can be registered and a charge secured without a court hearing and, in many cases, without direct notice of the registration itself. The CRA is generally required to have sent the taxpayer notice of the assessment and to have allowed the collection-restriction periods to run before taking these steps, but the registration of the certificate and the securing of the charge are administrative acts, not contested proceedings. This is one reason that responding to CRA collection correspondence early — before a certificate is registered — preserves far more options than waiting until a charge has already attached to title.
Dealing with an existing charge
Once a charge is on title, several routes can lead to its removal. The right one depends on the taxpayer's circumstances and on whether the underlying debt is genuinely owed.
- Pay the debt. The most direct route — paying the certified amount plus accrued interest — entitles the taxpayer to have the charge discharged. Where the funds come from a sale or refinancing, the charge is typically satisfied out of the proceeds on closing.
- Negotiate a payment arrangement. The CRA may agree to a payment arrangement on the debt. The charge usually remains on title until the debt is cleared, but an arrangement holds enforced collection in abeyance while it is honoured.
- Challenge the underlying assessment. If the certificate rests on an assessment that is wrong and still open to dispute, the priority is the objection or appeal. A successful challenge to the underlying tax removes the foundation for the certificate and the charge.
- Reduce the debt through taxpayer relief. Where interest has swollen the debt, a request to cancel interest through taxpayer relief can reduce the amount that must be paid to clear the charge.
- Negotiate a partial discharge on a sale. Where a taxpayer is selling and the sale proceeds will not cover the full debt, the CRA may agree to accept the available net proceeds and discharge the charge to allow the sale to close, with the balance of the debt pursued separately.
The interaction with other creditors
A registered tax charge takes its place in the priority of claims against the property alongside mortgages and other registered interests. Generally, claims rank by the order and time of registration, so a charge registered after an existing first mortgage sits behind that mortgage in priority. Where a property is sold or a power of sale is exercised, the proceeds are distributed according to those priorities. The interplay between a CRA charge, a mortgage, and any other registered claims can be intricate, and it is worth understanding the priority position before deciding how to deal with the charge.
Charges on property held jointly or by a spouse
A recurring question is what happens where the property is held jointly, or where the tax debtor is only one of two spouses on title. A CRA charge attaches to the debtor's interest in the property, not automatically to the whole. Where spouses hold title jointly, the charge generally binds the debtor spouse's share, which complicates — but does not necessarily prevent — a sale, because the non-debtor's interest is not the CRA's to claim. The exact effect depends on how title is held and on provincial property law, and the analysis can become involved where there is a question about who truly contributed to the property's acquisition.
A related issue arises where property was transferred between spouses before or after the debt arose. A transfer of an interest in the family home to a non-debtor spouse for less than fair market value can itself draw a separate derivative-liability assessment under section 160 of the Income Tax Act, which makes the recipient jointly liable for the transferor's tax up to the value transferred. In other words, moving the home out of the debtor's name to defeat a charge can create a fresh problem rather than solve the original one. The interaction between charges on property and section 160 exposure is something to assess together rather than in isolation.
How long a charge can sit
A registered charge does not expire on its own simply because time passes. While there are limitation rules that govern the collection of tax debts, the registration of a Federal Court certificate and the enforcement steps that follow can keep a charge effective against the property for a long period, and the CRA can take steps to maintain or renew its position. The practical reality for most taxpayers is that a charge will remain on title, accruing interest on the underlying debt, until it is affirmatively dealt with — by payment, by a successful challenge to the debt, or by a negotiated discharge. Waiting it out is rarely a viable strategy.
Selling or refinancing with a charge on title
When a taxpayer with a registered charge decides to sell or refinance, the charge comes to the foreground at closing. A buyer's solicitor will require clear title, and a lender will not advance funds behind an unaddressed CRA charge of meaningful size. In a straightforward sale where the net proceeds exceed the debt, the charge is simply paid out of closing and discharged, much like a mortgage. The difficulty arises where the proceeds will not cover the full debt. In that situation the taxpayer — ideally through representation — can approach the CRA to negotiate a discharge of the charge in exchange for the available net proceeds, with the unpaid balance of the debt handled separately afterward. Reaching that agreement before the closing date is far less stressful than discovering the problem on the eve of completion.
Why early action matters
The throughline of every option above is that they are wider and cheaper the earlier they are taken. Before a certificate is registered, a taxpayer can often resolve the debt or arrange terms without anything ever touching title. Once a charge is registered, removal almost always requires either payment, a successful challenge to the debt, or a negotiated discharge — and interest has been accruing the whole time. The certificate is not the moment to start engaging with the CRA; the assessment is.
How we approach the file
We start by establishing whether the underlying debt is correct and still open to dispute — if it is, the objection or appeal is the path that can remove the certificate's foundation entirely. Where the debt stands, we work the removal routes that fit the taxpayer's circumstances: a payment arrangement, a taxpayer-relief request to bring the interest down, or a negotiated discharge to let a needed sale or refinancing close. Throughout, the aim is to clear or contain the charge with the least cost and the fewest surprises on title.
