offsetting rent with trade skill

[Edwin Lau]

Some background to my current situation which may lead to an understanding why I would ask this question.

I am an electrician.  I currently rent a 2 bdrm apartment very close to the downtown area in Toronto Ontario for just under $1600 which I believe is under market value by ~$100.  I've been renting here for close to 2 years and in that time I have caulked all the base boards, tubs & sinks, upgraded the door handles and replaced the light fixtures with nicer ones.  I also do repair the range whenever elements burn out and replace worn out window screens - all out of pocket.  

I do this primarily because my landlord threatened to evict me after the handy man he hired to fix the sink used old parts (multiple times), so we've had to call him multiple times for the same issues. On top of this, the last tenant left the unit with a broken toilet and without a toilet tank lid and it cost him "a lot of money to fix" - which he wasn't happy about and seems to have taken his frustration out on us.

Now my question is - are there landlords out there (anywhere) that would lower the rent price to have a good tenant (I feel I'm a good tenant, please correct me if I'm mistaken) that can and will maintain the property if said tenant could not afford the market value?

Would it be absurd to use my trade skills to bargain for a lower rental cost? What would run through a landlord's mind if something like this were purposed?

I'm not suggesting to bargain with my current landlord, I am wondering if this would be an even remotely decent question to ask future landlords.

Thanks, and I apologize for the not-so-easy read
