Canadian rental etiquette

Coming from the US. What are some good practices as I'm looking for a place? What about as a tenant?

Is it poor form to negotiate rent with a landlord in a tenants market (aka plenty of housing available)? Ex. Asking for utility/utilities to be included in rent, asking landlord to match another property's rent or amenities, or lowering monthly rent in exchange for paying in advance?

I don't want to offend, but I also don't want to waste money.
