Landlord CA-ON] Rent increase and extension terms on CRE lease

Landlord renting a CRE space for retail purpose. I live jn canada and planning to lease on 5yr fixed term but can we increase the rent on year on year basis by a fixed amount or percentage ? If so What is the usual percentage of raise that's the norm? I don't want to quote something crazy that demotivates my tenant to proceed. Also My partner suggesting to have 5yr term with 5yr Extn but should we mention the extension period as a standard term in the agreement or can we have the term just for 5 years ? Advice pls
