Canada → Mexico & Caribbean

Mexico and the Caribbean attract Canadian snowbirds and retirees — but Mexico's fideicomisotrust requirement, the 183-day residency trigger, and the Caribbean's total absence of treaty protection create traps.

TaxKiln framework

Five-Stage Emigration Tax Lifecycle

TaxKiln's lifecycle framework for Canadian emigration tax: (1) pre-departure planning — asset reorganisation, CDA extraction, LCGE crystallisation, RRSP/TFSA timing, provincial residency strategy; (2) departure tax crystallisation — s.128.1(4) deemed disposition, T1243/T1161, T1244 security; (3) treaty positioning — Article IV tie-breaker, destination pension/RRSP treatment, withholding reduction; (4) post-departure compliance — Section 116 on TCP, Part XIII on passive income, provincial trailing tax; (5) return — s.128.1(7) basis reset, foreign retirement account elections, TFSA/RRSP room recalculation.

1. Mexican residency

The Ley del Impuesto Sobre la Renta (LISR) art. 9 triggers Mexican residency where the centro de intereses vitales is in Mexico (more than 50% of income or main professional activity) or physical presence exceeds 183 days. Mexican tax then applies to worldwide income; the Canada–Mexico treaty (1991) tie-breaker allocates residency.

2. RRSP withholding

Canada–Mexico treaty Article XVIII: periodic pension payments 15% (Article XVIII(2)(a)); lump sums 25% (default Part XIII). Mexican tax on foreign-source pension income applies with FTC for Canadian tax withheld.

3. CPP / OAS

The Canada–Mexico Social Security Agreement (1996) coordinates contributory periods. CPP/OAS taxable in Mexico (residence) with potential Canadian OAS recovery tax.

4. Fideicomiso — coastal & border property bank trust

Foreigners cannot directly own property within the restricted zone (50 km from coast, 100 km from border). Acquisition is structured through a fideicomiso — a Mexican bank trust holding legal title with the foreign buyer as beneficiary. Permits and annual bank trustee fees apply. The fideicomiso is generally not a Canadian s. 94 trust because beneficial interest mirrors direct ownership — but file T1135 if cost amount > CAD $100k.

5. The Caribbean no-treaty trap

Most Caribbean zero-tax destinations (Cayman, BVI, Bahamas, Turks & Caicos, Anguilla) have no income tax treaty with Canada. Consequences for Canadian non-residents living there:

Full 25% Part XIII withholding on Canadian-source passive income (no treaty reduction).
RRSP/RRIF withdrawals: 25% gross, no Article XVIII periodic rate.
No tie-breaker — CRA more likely to challenge residency on facts.
CRS (Common Reporting Standard) is active in these jurisdictions — bank-account information flows back to CRA automatically.
Elevated CRA scrutiny on the substance of departure (home, family, frequency of return visits).

Barbados, Jamaica, and Trinidad & Tobago do have treaties with Canada — Barbados' is particularly well-trodden for corporate structures but personal residency claims must satisfy the LOB-style provisions.

6. Snowbird framework — staying under 183

The cleanest snowbird position keeps Canadian residency intact: maintain significant ties (home, family, healthcare), stay <183 days in any non-Canadian jurisdiction (Mexico, US, Caribbean), and file Canadian-resident returns annually. Mexican condueño arrangements and US Form 8840 (Closer Connection) help preserve Canadian residency where day counts trend high.

Worked example — Albertans wintering in Puerto Vallarta

Persona: Bob and Linda, both 65, Calgary residents who spend October–April in Puerto Vallarta (≈210 days/year). Above the 183-day Mexican threshold → Mexican tax residency unless treaty tie-breaker shifts back to Canada. They retain a Calgary home, dependants in AB, primary doctors and provincial healthcare — Article IV tie-breaker should favour Canada; file Form RFC and Mexican return claiming treaty residency. Their Puerto Vallarta condo is in the restricted zone via fideicomiso; T1135 required (cost basis ≈ CAD $420k). They continue to pay Canadian tax on worldwide income; Mexican property tax (predial) and bank trustee fees are non-deductible personal expenses.
