There is no consolidated filing in Canada, so losses move by structure
Every corporation files its own T2 and pays tax on its own income, which means a loss sitting in one company is invisible to the profitable company beside it until something real changes. Canada, unlike some other countries, has no group or consolidated tax return. So when an owner asks how to use Lossco's losses against Opco's profits, the honest answer is: by rearranging real things, the income-producing assets, the financing, or the corporations themselves, so that the income and the loss end up inside the same taxpayer.
The pattern shows up constantly in owner-managed groups. A profitable operating company sits beside a startup venture burning cash, or a holdco carries a property running at a loss while the opco pays tax at full rates, or an older company holds losses from a bad stretch years ago while its successor thrives. In every case the group as a whole is paying tax on income it has not really earned, and the fix is structural.
The losses are worth the effort because they are long-lived but not eternal. Non-capital losses, the ordinary operating kind, carry back three years and forward twenty. Net capital losses carry forward indefinitely but can only ever offset capital gains. A loss corporation with no realistic path back to profit is a wasting asset: every year that passes without a plan burns time off the carryforward clock while the profitable company keeps paying tax next door.
The reassuring part is that CRA has long accepted loss-consolidation planning inside a related or affiliated group, provided each step is legally effective and commercially real. The dangerous part is the opposite pattern: a management fee invented at year-end with no agreement, no invoice and no payment, or losses acquired from strangers. The first gets reassessed on the facts; the second is what the anti-avoidance rules were written to stop.
Four techniques do most of the work
Nearly every loss plan inside a private group uses one of four tools, and the right one depends on how large the loss is, how quickly it needs absorbing, and whether the corporations need to stay separate. In rough order of how often we see them:
- Intercompany charges. The profitable company pays the loss company management fees, rent or interest for something real: management services actually performed, premises actually occupied, money actually borrowed. The charge must be reasonable for what is provided, supported by an agreement, invoiced and paid. HST has to be handled as well, since fees between corporations are normally taxable supplies, though closely related corporations that qualify can elect to treat certain intercompany supplies as made for nil consideration. Best for shifting a steady, moderate amount of income every year.
- A loss-consolidation loan. A structured financing inside the group: the loss company lends to the profitable company at interest, the profitable company deducts the interest, and the interest income lands where the losses can absorb it. The funding circle is usually completed with intercompany share subscriptions so no outside cash is needed. These arrangements are established planning within affiliated groups, but every leg has to be legally real, documented and actually transacted.
- A section 85 asset transfer. Move an income-producing asset, a rental property, an investment portfolio, a division, into the loss corporation on a tax-deferred rollover, so its future income is earned where the losses sit. The rollover defers tax on the transfer itself; the election paperwork and elected amounts have to be right, and the T2057 has its own filing deadline.
- Amalgamation or wind-up. Merge the corporations under section 87, or wind a subsidiary up into a parent that owns at least 90% of it under section 88. The continuing corporation generally inherits the loss carryforwards with their character intact, subject to the control rules below. This is the permanent fix for the common case where there is no longer any reason to run two corporations.
| Technique | How the loss gets used | Best suited to | Watch for |
|---|---|---|---|
| Management fees or rent | Shifts taxable income to the loss company each year | Ongoing, moderate profit shifting between operating companies | Reasonableness, real services, invoices, HST treatment |
| Loss-consolidation loan | Creates deductible interest in Profitco, income in Lossco | Larger balances inside an affiliated group | Every leg must be legally executed and papered |
| Section 85 transfer | Moves the income source itself into the loss company | Property or portfolios with dependable income | Election deadlines, elected amounts, land transfer tax on real property |
| Amalgamation or wind-up | Puts income and losses inside one corporation permanently | Groups that no longer need separate entities | Loss continuity rules, creditor and contract consents, timing of when losses open up |
The rules that police it
Three sets of rules decide whether a loss plan survives review: reasonableness, legal effectiveness, and the stop-loss and anti-avoidance provisions. Reasonableness means a management fee has to correspond to management actually provided, at a price that makes commercial sense; the Act lets CRA deny whatever portion of an expense is unreasonable, and intercompany fees between related parties are a standing audit favourite.
Legal effectiveness is the quiet killer. The agreement, the directors' resolutions, the invoices and the actual movement of funds all have to exist, dated when the transactions happened. A December 31 journal entry recording a fee nobody contracted for, invoiced or paid is the classic reassessment, and it usually fails on the facts before anyone reaches the anti-avoidance rules.
Timing discipline matters as much as paper. Management fees should be set by agreement before the year they cover, charged through the year and actually paid, not discovered at year-end to be exactly the size of the loss. A fee that tracks the loss to the dollar, every year, invites the question of what was really being bought. Set the charge on the value of what is provided and let the loss absorption follow.
The stop-loss rules matter when property moves. Selling a loss property to an affiliated corporation does not trigger the loss; it suspends it, parked until the property leaves the affiliated group. So you cannot crystallize a capital loss by selling the asset to your own holdco, and a plan that assumed you could needs redesigning rather than filing.
Finally, the boundary line: consolidating losses within a group you already own is accepted; importing someone else's losses is not. And note that related corporations under common ownership are usually also associated, which means they share one $500,000 small business deduction between them and their passive income is measured group-wide. Restructuring to use losses can change both, so the CCPC tax profile of the whole group gets modelled before anything moves.
An acquisition of control resets the board
When control of a corporation changes hands, its accumulated losses stop being freely usable, which is why loss planning has to happen before a purchase, a reorganization or a falling-out among shareholders, not after. An acquisition of control triggers a deemed year-end, which burns a year off every carryforward and forces a short-year filing. Net capital losses die outright. Accrued but unrealized losses on property are forced to be recognized and swept into the pre-change pools.
Non-capital losses survive, but only conditionally: the business that generated them must be carried on throughout the year with a reasonable expectation of profit, and the losses can only be applied against income from that business or a similar one. That is a test about what the corporation actually does, the same territory as active business income, and it is why buying a corporation purely for its tax losses almost never works as hoped.
The trap for family groups is that these rules do not care about intent. An estate freeze, a shareholder buyout or a split-up between siblings can move control as a side effect, and the loss position should be checked before the reorganization closes, while the steps can still be ordered to protect it.
If a change of control is coming, the window before closing is when the losses can still be used freely. Standard moves include triggering accrued gains on group assets so expiring losses absorb them, or applying losses against the current year's income before the deemed year-end cuts it short. After closing, the streaming rules govern and the options narrow to running the same business profitably. The difference between planning a month before and a month after is often the entire value of the pools.
Owner-level consequences ride along
Rearranging where the group's income lands also rearranges where your own compensation comes from, so the owner-level plan has to be rebuilt alongside the corporate one. Salary should be paid by the corporation that actually employs you, and the deduction is worth more in a company paying tax than in one sheltered by losses. Dividends carry their corporate history with them: a company paying no tax generates no refundable tax, and RDTOH sitting in one corporation only comes back when that specific corporation pays taxable dividends.
Intercompany balances deserve the same discipline as fees. Money drifting between the holdco, the operating company and you personally, with no notes, terms or repayments, is how shareholder loan problems start, and the shareholder benefit rules do not pause because the group was busy with a loss plan.
One more interaction worth naming: if the loss company ends up holding the group's investment portfolio, its losses can absorb the investment income, but that income still counts toward the group's adjusted aggregate investment income. Past $50,000 a year, it grinds the shared small business limit for every associated corporation. Using losses efficiently and protecting the 12.2% rate are two dials on the same machine.
None of this changes the household arithmetic of year-end compensation planning: you still need a set amount of cash, and TOSI still polices anything flowing to family members. What changes is which corporation the cash should come from, and in what form, once the group's income has been rearranged. Redo that math in the same meeting, not the following spring.
What changes the answer, and how it is handled
Five facts decide which technique fits, and they are worth writing down before anyone drafts a step plan:
- The type and size of the loss. Non-capital losses respond to income shifting; net capital losses only to capital gains, which usually means moving or realizing the right assets.
- Where the loss sits versus where the profit is earned. Parent-subsidiary pairs open up wind-ups; sister companies point to fees, loans or amalgamation.
- Whether the corporations must stay separate. Liability walls, licensing, lender covenants or a coming sale can rule out a merger regardless of the tax math.
- Whether control will change. A sale, succession step or shareholder exit on the horizon can restrict or destroy the losses mid-plan.
- How long the loss will take to absorb. A one-time fix suits a rollover or amalgamation; a decade of gradual absorption suits annual charges with standing agreements.
Expect a real loss plan to produce artifacts you can point to: intercompany agreements, promissory notes and resolutions dated when the steps happened, elections filed on time, and a memo recording why the structure was chosen. That file is what turns a reassessment inquiry into a short correspondence. If the plan cannot produce the file, it is not a plan yet.
This is defined-scope reorganization work, not something to improvise at filing time, and it is the kind of engagement we run as a Strategic Project: the group mapped, the technique chosen against those five facts, the agreements and elections executed in the right order. It usually pairs with the annual rhythm of corporate tax planning for owner-managed businesses, since the same review that finds trapped losses also finds the SBD, RDTOH and compensation issues around them. If your current accountant files two clean T2s and has never mentioned the loss sitting in one of them, that is the difference between filing and planning; a corporate tax planning CPA in Ontario should be raising it with you, and Corporate Restructuring is where we fix it, with the scope and fee in writing after a free 15-minute discovery call.
