Yes, it's definitely possible to pursue a baking course even with a prior degree in business/commerce! Many people switch careers to follow their passion, and baking is a fantastic choice. In terms of areas/provinces, I'd recommend looking into bigger cities or regions known for their culinary scenes, such as British Columbia (especially Vancouver) or Ontario (Toronto area). These places generally have more job opportunities in the food and hospitality industry.
Regarding moving with your spouse and child, it is usually possible to apply for visas together, but it depends on the specific immigration rules of the country you're moving to. I'd suggest consulting with an immigration advisor or looking at the official immigration website for the country you're considering.
Good luck with your career change and your move! If you need more help, feel free to ask. 😊
