I just became a licesnced business so here's what I know, there are kind of a few parts to it... I rent a space, but got all the info reguarding home biz too...
If I were to be baking out of my own home.. I'd need these things:
master biz lic A.K.A biz name registration,
food handler cert,
Vendor permit A.K.A PST A.K.A RST #,
biz registration A.K.A GST#,
(GST and PST to become harmonized, not sure how that will affect me yet)
Permitted Use Letter - from city zoning - (I got this before I knew I didn't need it!! A waste of $75 dollars and 10 day waiting period.. lol.. grrrrr....)
Health inspection and Dinesafe pass
Professional Biz Lic from City lic. bureau
Fire Safety inspection
A sign permit if that person wants to display a sign
and the kitchen (a totally separate kitchen from your everyday use one) must meet the minimum requirements set by the city - as in the special exhaust hood that I believe has to be professionally tested and checked twice a year, triple sink, safe storage, etc...
I hope that helps... If you have more questions feel free to ask.. I might know the answer.. lol.. I might not!!
Good luck everyone!!
Oh!! P.S... this is for the city of toronto..
