Direct answer
To enter Canada as a visitor you need either a temporary resident visa, often called a visitor visa, or an electronic travel authorization, the eTA, depending on your nationality and your mode of travel. As a general rule, nationals of visa-required countries apply for a visa, while nationals of visa-exempt countries arriving by air apply for an eTA, an electronic document linked to the passport. In both cases, the authorization only lets you present yourself at the border: the border services officer decides on admission and on the length of the stay, generally six months. An extension can be requested from within Canada, before your status expires. Always check your situation on Canada.ca, because country lists and requirements change.
Visa or eTA: the first question to settle
This is the question that comes up most, and the answer depends on only two things: your nationality and how you enter Canada.
Nationals of visa-required countries must obtain a temporary resident visa before departure. The application is made online, it requires supporting documents, often biometrics, and it takes time.
Nationals of visa-exempt countries arriving by air must instead hold an electronic travel authorization. The eTA is an electronic document tied to the passport, obtained through a short form. Watch one point that catches many travellers out: the eTA is linked to the passport number. Change passports and you will need a new one, even if the old eTA had not expired.
Your mode of travel matters too. Requirements differ depending on whether you arrive by air, by land or by sea, and certain categories of traveller fall under particular rules. <!-- TODO verify --> The only reliable way to settle your case is the official verification tool on Canada.ca, which asks for your nationality, residence status and mode of entry, then tells you which document is required.

What visitor status allows, and what it forbids
Many problems come from a misunderstanding of what visitor status permits.
What you can do
A visitor can stay in Canada for tourism, visit family or friends, attend a wedding or a funeral, take part in a conference, a trade show or business meetings, and attend a job interview. A visitor may also take certain short courses without a study permit, within the limits set by the regulations.
What you cannot do
A visitor cannot work in Canada, in the broad sense Canadian law gives that word: a paid activity, or an activity that competes directly with the Canadian labour market, even unpaid. That definition is wider than the intuitive idea of a job, and I devote a whole article to it, working without a permit in Canada, including the rare permit-exempt categories such as the business visitor.
A visitor also cannot enrol in a long study program without a study permit, nor access public health insurance on the same terms as a resident, which makes private travel insurance essential.
The evidence that makes the difference
A visitor visa application is a demonstration, not a form. Here are the four blocks an officer examines.
The purpose of the trip
Be precise and verifiable. A tourist stay comes with an itinerary, a booking, a ticket. A family visit comes with an invitation letter stating who is hosting you, at what address, for how long and under what conditions. A business trip comes with a letter from your employer or the host company.
Financial means
You must show you can support yourself during the stay and leave afterwards. Bank statements for the last few months, proof of income and, where applicable, your host's commitment to support you form the base. What counts is not only the balance but the coherence: an account topped up by a large deposit the day before the application raises more questions than it answers.
I deliberately quote no reference amount, because there is no universal scale: it depends on the length, the season, the type of stay and any support provided. <!-- TODO verify --> The reasoning to apply is the one I describe in proof of funds for Canada: cost out your stay, then prove you have that money.
Ties in your home country
This is the decisive block, and the most often neglected. The officer must be satisfied you will leave Canada at the end of your stay. A stable job with an employer letter stating your approved leave, home ownership, a business, dependants who stay behind, studies in progress, community commitments: all of it describes a life you will return to.
A young person without a fixed job, without dependants and without property is not suspicious, but they objectively have fewer ties to document, and their file has to compensate elsewhere, for instance with a precise purpose of travel and credible support.
Travel history and honest declarations
A history of respected trips, with returns on time, is a considerable asset. Conversely, an old overstay, a previous refusal or a removal must be declared, explained and documented. Concealing a refusal is a very bad idea: systems talk to each other, and an omission turns into misrepresentation, with consequences far heavier than the initial refusal. That is exactly the logic I describe in immigration file mistakes.
Length of stay and the border itself
Here is the distinction most travellers miss, and it has concrete consequences.
A visa or eTA does not give the right to enter: it gives the right to present yourself at the border. Admission is decided by a border services officer, who also sets the length of the authorized stay. As a general rule a visitor is admitted for six months, but the officer can grant a different period, shorter or longer, which they then write in the passport or on a document given on arrival.
Hence my standing advice: check what you were granted before leaving the arrivals area. If no date is written and no document is given, the general six-month rule applies in principle, but it is better to know than to assume. Note the deadline in your calendar that same day, with a reminder a month ahead: nearly every out-of-status situation I see comes from a forgotten date.
Prepare the crossing too: address where you will stay, host's contact details, return ticket, proof of travel insurance, and the ability to explain the purpose of your trip in one clear sentence. My general arrival advice is in preparing your arrival in Canada.
Extending a stay from inside Canada
You can ask to stay longer, and that process has its rules.
The application to extend visitor status is filed from within Canada, online, before your current status expires. That anticipation is the golden rule: filing before expiry generally lets you remain in Canada while the application is processed, whereas filing afterwards creates an out-of-status situation that must be fixed through a separate procedure, bounded by a strict deadline and with no guarantee of success.
An extension needs a reason: family circumstances, an event, medical treatment, an unforeseen travel problem. It rests on the same evidence as the initial application, financial means and intention to return included, brought up to date. Fees and timelines are on the official page. <!-- TODO verify -->
Two frequent errors. The first is believing that leaving and immediately re-entering, for instance a quick trip to the United States, automatically resets the clock: admission is reassessed on every entry, and a pattern of repeated stays attracts attention. The second is staying beyond the authorized date on the assumption nobody will notice: an overstay goes on the record and will weigh on all your future applications, including for permanent residence.
The practical file: forms, biometrics and the online account
Now to the mechanics, because a good file badly submitted is still a bad file.
The online application
The application is made online, in a secure account that then becomes your channel of communication with IRCC. Create that account in your own name, with an email address you actually check, and keep your credentials safe. Never hand those credentials to a middleman: an authorized representative has their own access, and anyone asking for your codes is exposing you to fraud, as I explain in avoiding immigration misinformation.
Download the forms on the day you fill them in, not weeks ahead: an outdated version can get a file returned. Complete every field, including the address and employment history sections, and avoid blank boxes or vague entries, which trigger requests for more information.
Biometrics
In many cases, biometrics are required: fingerprints and a photo, taken at a designated service point. The fee is $85 per person, validity is 10 years, and you normally have 30 days after the instruction letter to attend. That ten-year validity is good news for regular travellers: once given, biometrics serve subsequent applications for the whole period.
Plan for appointment availability, which varies widely by country, and for travel time if the designated service point is in another city. I set out how it all works in biometrics for Canadian immigration.
Documents and their translations
Any document that is neither in English nor in French must be accompanied by a proper translation, with the required attestations. Scan cleanly, respecting the requested formats and file sizes: an illegible document counts as a missing one. Name your files clearly, because a readable file is processed faster than a confusing one.
The special cases that come up often
Four situations deserve a mention, because they fall outside the general logic.
Transit through a Canadian airport, first. Stopping over in Canada on the way to another country does not necessarily exempt you from an authorization, and particular rules exist for transit depending on nationality, itinerary and airport. <!-- TODO verify --> Check this before buying a ticket with a Canadian connection: it is a classic cause of denied boarding.
Minors travelling alone or with one parent, next. Canadian authorities expect documents establishing parental authority and, where applicable, the other parent's consent, consistent with the applicable custody orders. A clear, dated and signed consent letter, with the absent parent's contact details, avoids a great deal of trouble on arrival.
Dual nationals, next. Someone holding Canadian citizenship alongside another nationality is subject to specific travel rules about which document to present when entering Canada. <!-- TODO verify --> If you discover you may be a Canadian citizen without knowing it, which happens more often than people think, start with checking whether you are already a Canadian citizen: the step to take is then not a visa application.
Permanent residents of Canada, finally, who fall under neither the visitor visa nor the eTA: they travel with their permanent resident card or, failing that, with a specific travel document. Never apply for an eTA if you are a Canadian permanent resident; it is a frequent error that creates confusion in the systems.
The most frequent grounds of refusal
A visitor visa refusal is almost never arbitrary. In the letter, the grounds recur with striking regularity.
The first is insufficient ties to your country of residence: the officer is not satisfied you will leave. The second is insufficient financial means, or means inconsistent with the length and type of stay announced. The third is a purpose of travel that is poorly documented or not credible given your situation. The fourth is a problematic history: an overstay, an unexplained previous refusal, contradictory information between applications. The fifth, more technical, is an incomplete file, a missing translation or a badly completed form.
There is no formal appeal against a visitor visa refusal, but nothing prevents a new application. The only strategy that works is to identify the exact ground, requesting the officer's notes if needed, then to fix that specific point. Resubmitting the same file hoping for a different officer is the surest way to accumulate refusals, and each refusal makes the next one harder.
Visitor, super visa, work permit: do not confuse the doors
Many plans fail because the wrong door was chosen at the outset.
If you are coming for tourism, a family visit or occasional business activities, the visitor visa or eTA is the right door.
If you are the parent or grandparent of a Canadian citizen or permanent resident and want to stay a long time, the super visa is almost always preferable: up to ten years of validity, stays of up to five years per entry and a possible two-year extension, in exchange for $100,000 medical insurance and an income threshold the host must demonstrate. I set out the conditions in the super visa.
If your goal is to work, no visitor status will do, apart from the rare permit-exempt categories. And if your goal is to settle for the long term, permanent residence is what to look at, through the programs I describe in permanent residence in Canada. Using a visitor visa as an antechamber to permanent settlement is a bad calculation: officers know that pattern perfectly well.
Frequently asked questions
Do I need a visa or an eTA to travel to Canada?
It depends on your nationality, your residence status and your mode of entry. As a general rule, nationals of visa-required countries apply for a temporary resident visa, while nationals of visa-exempt countries arriving by air apply for an electronic travel authorization. Particular rules apply depending on the mode of transport and to certain categories of travellers, notably permanent residents of other countries. The lists change: use the official verification tool on Canada.ca, which gives you the answer in a few questions, rather than a list copied onto a third-party site.
How long can I stay in Canada as a visitor?
Generally six months, but the border services officer decides the length on each entry and may grant a different period. Always check the date written in your passport or on the document given on arrival, and note it immediately with a reminder a month before it expires. If you want to stay longer, the extension application is filed from within Canada before your status expires. Staying beyond the authorized date creates an out-of-status situation that will weigh on all your future applications.
Can I work or study on a visitor visa?
Not work, apart from the rare permit-exempt categories such as the business visitor who comes to negotiate or attend meetings on behalf of a foreign company. The Canadian definition of work also captures certain unpaid activities that compete with the local labour market, which surprises many travellers. As for studies, a visitor may take certain short courses, but a long program requires a study permit. If you are unsure about a specific activity, check before starting rather than after.
What do I do if my visa application is refused?
Read the refusal letter carefully, as it states the grounds relied on, and request the officer's notes if you need to understand the exact reasoning. There is no formal appeal for a visitor visa, but you can file a new application provided you genuinely fix the weak point: strengthen the evidence of ties, clarify the purpose of the trip, document your financial means, explain a past event. Resubmitting an identical file is pointless and stacks up refusals, which complicates every later application, including under other programs.
Does an invitation letter guarantee the visa?
No. An invitation letter is a useful document, sometimes essential to establish the purpose of the stay, but it does not bind the officer and it compensates neither for weak ties in your home country nor for insufficient funds. It must be dated, signed, precise about the host's identity and status, the address, the expected length and the accommodation arrangements, and consistent with the rest of the file. A generic letter, visibly copied from a template, weakens a file more than it helps.
Does my eTA change when I renew my passport?
Yes, and it is one of the most frequent oversights. The electronic travel authorization is linked to the passport number it was issued with. If you get a new passport, you must apply for a new eTA before travelling, even if the old one has not reached its expiry date. Check this several weeks before departure, because boarding can be refused at the airport if there is no valid eTA linked to the passport presented.
