AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A three-month stay in Lagos while keeping your Canadian job does not on its own end your Canadian tax residence if you keep your home, family and other ties here, and in Ontario it fits within OHIP's rules, which require 153 days in Ontario in any 12-month period. The Nigerian side needs more care: Nigeria's residence tests go beyond 183 days, and work physically done in Nigeria can raise Nigerian tax questions. Get your employer's written approval first.
Start with your employer
Working abroad is an employer decision before it is a tax one. Many Canadian employers allow short remote stints abroad but need to check payroll, data security, insurance and whether your presence in Nigeria creates obligations for them there. Ask in writing, give dates, say what work you will do, and get the answer in writing. If you work without approval and something goes wrong, from a data breach to a tax letter, you carry the risk.
Your Canadian tax residence
The CRA's guide T4131, Canadian Residents Abroad, describes a factual resident as someone who keeps significant residential ties with Canada while living or travelling abroad. The significant ties are a home in Canada, a spouse or common-law partner, and dependants who stay here. Secondary ties include personal property such as a car, social ties, a Canadian driver's licence, Canadian bank accounts and credit cards, and provincial health insurance. Someone who leaves for three months, keeps a flat in Calgary and comes back to the same job is in the ordinary case still a factual resident and keeps filing as a resident, reporting worldwide income.
The Nigerian side
Residence tests
Under the Nigeria Tax Act 2025, as summarised by PwC (reviewed 29 May 2026), you are resident in Nigeria if any one test applies: domicile, a permanent home available for your domestic use, habitual abode, 183 days or more in any 12-month period (counting temporary absences), substantial economic or immediate family ties, or diplomatic status. Three months is below 183 days, but if you also keep a home in Nigeria or your spouse and children live there, another test may catch you. If both countries treat you as resident, the Canada–Nigeria double taxation agreement, in force since 16 November 1999, decides which has the main claim; see the tie-breaker rules.
Work done in Nigeria
The NiDCOM-hosted NGEX diaspora guide (January 2026) says non-residents are taxed in Nigeria only on Nigerian-source income, and that income for services physically rendered outside Nigeria is not taxable there. Three months of work done from a Lagos flat is work physically rendered in Nigeria, so the guide's comfort does not apply in the same way. The double taxation agreement contains rules for employees on short stays paid by a foreign employer; we have not reviewed its text here, so ask a tax adviser with your facts. This is information, not advice. If you are also over the Nigerian 183-day mark across any 12 months because of earlier visits, read Nigerian residency after a long visit.
Keeping provincial health cover
Each province sets its own absence rules. In Ontario, the government's OHIP page (updated 21 July 2025) says you must be physically in Ontario for 153 days in any 12-month period, with certain exceptions, and that if you have been outside Ontario for more than 212 days in any 12-month period you may need to reapply. Three months away fits, but count the whole 12 months, including other trips. Ontario also says, on its page about coverage outside the province, that it recommends buying private health insurance before leaving. Provincial plans cover only part of the cost of care abroad, if any, so buy travel medical insurance that covers your whole stay in Nigeria, and check whether it excludes work trips or pre-existing conditions. Residents of other provinces should check their own plan's rules.
| Check | Why |
|---|---|
| Days outside your province in the last 12 months | Ontario's 153-day presence and 212-day absence figures are rolling |
| Travel medical insurance for Nigeria | Ontario recommends private cover before leaving |
| Employer's written approval | Payroll, data and insurance obligations |
| Nigerian residence tests | Home, family ties or earlier stays can make you resident |
| Immigration status in Nigeria | Nigerian citizens enter on their passport; others should check NIS rules for working while visiting |
Before you fly
- Get written approval from your employer, with dates.
- Count your days outside your province over the last 12 months.
- Buy travel medical insurance for the full stay.
- Work through the Nigerian residence tests and note any that apply.
- Keep your Canadian home, accounts and address unchanged, and keep travel records.
Money while you are there
You will be paid in CAD into your Canadian account and spending in naira. Card foreign transaction fees and ATM charges add up over three months. Plan how you will move money to naira, and keep receipts if any costs are reimbursable by your employer.
Where Pryme fits
A Pryme Personal Account, opened from Canada, holds NGN alongside USD, GBP and EUR, so you can move money into naira for rent, transport and family costs and pay bills in Nigeria from one app. Swap shows the rate and the fee before you approve. Naira deposits are held by a licensed Nigerian microfinance bank and insured by the NDIC up to the applicable limit. Set up security with an authenticator app before you travel.
Questions people ask
Will three months in Lagos make me non-resident in Canada?
Usually not if you keep significant residential ties, such as a home, spouse or dependants in Canada. The CRA treats such people as factual residents who keep filing as residents.
Will I lose OHIP if I work in Lagos for three months?
Ontario requires 153 days physically in Ontario in any 12-month period and says more than 212 days away may mean reapplying. Three months fits if your other trips do not push you over.
Do I pay Nigerian tax on my Canadian salary while in Lagos?
Possibly. Work physically done in Nigeria can be Nigerian-source income, and Nigeria's residence tests include home and family ties as well as 183 days. The Canada–Nigeria agreement has short-stay rules; ask an adviser.
Do I need my employer's permission to work from Nigeria?
You should get written approval. Working abroad affects your employer's payroll, insurance and data obligations.
