Holding companies, family trusts, and estate freezes each get explained on their own most places — which hides the thing that actually matters: where in the chain tax gets triggered, and where it genuinely doesn't. This is the map.
Most explanations of holding companies, trusts, and estate freezes treat each one as its own self-contained topic. That's fine for learning any one piece, but it hides the thing that actually matters when you're looking at the whole structure: which handoffs above genuinely defer or eliminate tax, and which ones just move the same tax bill to a different place. Walking down the chain:
If you work in the business, you're paid salary (a T4, taxed as ordinary personal income, generating RRSP room and CPP contributions) or dividends (a T5, taxed personally at a lower rate but generating no RRSP room and no CPP). Salary vs. dividends is its own real decision, not a formality.
Dividends paid from an operating company up to a connected holding company generally move without triggering permanent double tax — the mechanics run through the Refundable Dividend Tax on Hand (RDTOH) account, not a flat "tax-free" pass-through. This is the whole reason a holdco exists: it lets retained earnings sit somewhere with less exposure to the operating company's business risk. How a holding company actually works →
Money reaches a family trust one of two ways: the holdco pays it dividends directly, or — more often, for a business with real growth ahead of it — an estate freeze locks the founder's current value into fixed-value preferred shares and routes all future growth into common shares the trust holds from day one. Either way, the trust is now a genuine owner, and its own 21-year clock (below) starts running the moment it's settled.
If a founder owns more than one operating company through the same holdco or trust structure, the associated corporations rules mean those companies likely share one small business deduction limit, not one each — worth checking before assuming the tax rate on the way up.
A trust is deemed to sell and immediately reacquire its capital property every 21 years, whether or not anything was actually distributed — the single highest-value fact to know if a trust is part of your structure. Assets distributed to beneficiaries before that anniversary reset the clock for that property; assets left inside the trust past it trigger real capital gains tax with nothing sold to fund it. The full mechanics, and the trap next to the trap →
A trust distribution retains its character on the way out — a capital gain stays a capital gain, an eligible dividend stays an eligible dividend, taxed on the beneficiary's own T1 at their own rate. This is exactly where the Tax on Split Income (TOSI) rules step in: distributions to a spouse or adult child who isn't genuinely, substantially involved in the business get taxed at the top personal rate regardless of that beneficiary's actual income, unless a specific exclusion applies. Who TOSI actually catches → Dividend flows that skip the trust and go straight from a holdco or opco to an individual hit the same personal tax layer — see eligible vs. non-eligible dividend tax credit treatment.
This is where every branch above eventually converges. Shares held personally, a trust's remaining property, and any assets never distributed all face a deemed disposition at death — on top of whatever probate applies to what passed outside the trust. This isn't a separate topic from the structure above; it's the same structure's last handoff.
