After you land as a permanent resident in Canada, you can live, work and initiate entrepreneurial activity in any province or territory in Canada.  This province or territory can be different than the one you initially chose in your application for immigration (except Quebec).

You should prove the origin of your wealth through trustworthy documents issued by third parties like: income tax declaration, payroll slips, invoice for  services, register of transfer (sell or buy) of real estate, securities ownership certificate, ownership of business or real estate, etc.  You should be able to prove that your wealth was accumulated through means considered legal, including gifts or inheritance.

As an investor, you can work and you are authorized to initiate entrepreneurial activity in Canada; however it is not a requirement.

You should deposit the C$800,000 (Canadian dollars) required before the final approval by CIC.

As an entrepreneur applicant, it is recommended that you have an Exploratory Visit to Canada to assess the commercial landscape of the area where you plan to establish your business.
ConnectCA strongly recommends that you do so. If you plan to replicate your previous business experience from your home country to Canada, you risk loosing all your capital! An exploratory visit will give you invaluable insights for your future business in Canada.

As a self-employed individual, it is recommended that you have an Exploratory Visit to Canada to assess the cultural, artistic or business landscape of the area where you plan to establish.
