Some months the bill will be more than $400 and some months less but it should average out.A couple tips: increase the bill by about 10% to cover tenants that abuse the utilities ($110 per tenant, $40 extra for you).

Still in the process of fixing up the main floor unit from the abuse it took from previous renters.  

I don't care how well you rehab the house and if U pull all permits if your tenant base is abusing and transient your goose is cooked before you ever started.. 

I wish it was easier to fire bad tenants in Ontario :-)Besides the verbal abuses, a landlord has a choice on other hardships as well.

I also highly advise you attend a few LTB hearings in your area before you invest to get a feel for the abuse of landlords in Ontario.

(a) A tenant to a residential lease may terminate a lease agreement in the manner provided in this section without penalty or liability, if the tenant or another authorized occupant fears imminent violence after being subjected to:(1) domestic abuse, as that term is defined under section 518B.01, subdivision 2;(2) criminal sexual conduct under sections 609.342 to 609.3451; or(3) stalking, as that term is defined under section 609.749, subdivision 1.

Also, maybe add something to the lease such as:"Any repairs due to tenant abuse or negligence which must be done immediately will be added to the next month's rent as 'additional rent.' 

I also want to make my rentals "bullet proof" so that they hold up to wear and tear and a little abuse.

Don't even consider it.Second if it is viable you must keep in mind that tenants will abuse and generally beat the hell out of a property.

Waiting to tell them until dates have passed will only prolong them relisting and trying to sell to someone else.
