Canada: Tourist visa holders can't work without permit.

No, you cannot use a tourist visa to work in Canada. A tourist visa, also known as a visitor visa or Temporary Resident Visa (TRV), is specifically for individuals who intend to visit Canada temporarily for tourism, visiting family or friends, or participating in short-term activities that do not involve paid work.

To work in Canada legally, you generally need a work permit or authorization that allows you to engage in employment activities. There are different types of work permits available depending on factors such as the nature of the work, the duration of stay, and the individual's qualifications. Some common types of work permits in Canada include:

1. Open Work Permit: This type of work permit allows you to work for any employer in Canada without the need for a specific job offer. Open work permits may be issued based on eligibility criteria such as being a spouse of a skilled worker, a graduate of a Canadian institution, or a participant in certain immigration programs.

2. Employer-Specific Work Permit: If you have a job offer from a Canadian employer, you may apply for an employer-specific work permit. This permit is tied to a specific employer and may have conditions such as the duration of employment and location of work.

3. International Experience Canada (IEC): The IEC program provides opportunities for young people (usually aged 18-35) from participating countries to work and travel in Canada for a limited period under specific categories such as Working Holiday, Young Professionals, and International Co-op (Internship).

4. Labour Market Impact Assessment (LMIA): In some cases, employers in Canada may need to obtain an LMIA to demonstrate that hiring a foreign worker will not negatively impact the Canadian labour market. This process is often required for employer-specific work permits.

It's important to note that attempting to work in Canada without the appropriate work authorization is against Canadian immigration laws and can result in serious consequences, including deportation and future immigration restrictions. If you are interested in working in Canada, explore the various work permit options and ensure that you obtain the necessary authorization before engaging in employment activities.
