What is the difference between Canadian business visa and start-up visa?
The major difference between Business Visa and Start-Up VIsa is that the Start-Up Visa (even though it is called a 'Visa') is the Permanent Residency in Canada path. However, the Business Visa is a temporary visa for businessmen to come to Canada for an extended period of time to build a new business or operate an existing one. Business Visa comes with the proper Canadian Work Permit issuance with the business that the candidate intends to operate as an employer.
Start-Up Visa has an incorporated opportunity to come to Canada before (!) the Permanent Resident of Canada status is granted, and that is also a Work Permit - that is the only similarity of these two programs.
Overall, both programs are complex but very useful and lucrative for business-people. Therefore, consultation is highly recommended to select a proper path.
