My tenant wants major renovations done to the house she is renting to accomodate her elderly mother. I told her I will look into it, but she told me I am "required by law" to do this. Thoughts before I get a lawyer?

Question

I live in the province of Ontario. I just wanted to ask in here before I get a lawyer involved. 
My tenant has been renting a two-story century home from me for a few years. She wants her elderly mother to move in with her, but wants me to install and pay for all these things:
- Stair lift to the front door (6 steps)
- Stair lifts for the two staircases in the home
- Upstairs bathroom renovation to make the bathroom bigger and have a shower she can wheel her mom into
- Ceiling lift that has a rail from the bathroom to the bedroom
- Widen all the doorways to accommodate her mom's wheelchair
- Remove all carpet and install flooring instead
I told her these are major renovations and will take time and likely several tens of thousands of dollars. She told me I am "required by law" to make these changes. I told her that I would have to review that and would get back to her by April 24th.
Her mom is not my tenant. Her mother is not on the lease. Her mother doesn't live at the house now and never has. My tenant wants these renovations done so that her mom can move in with her. I feel like it would be different if the person needing these accommodations was my tenant. 
Anyone have experience with a situation like this? Were you legally required to undertake over $40k in renovations (not all of which can be done due to the physical structure of the home)?
I'm contacting my lawyer on Monday but I just want to be prepared.
UPDATE: 
Long story short, her mom lives in a nursing home and has abysmal credit. My tenant says this is because she had one unpaid bill that went to collections but her credit score shouldn't be the deciding factor. I said sorry, it's clear in the application that tenants need to have a credit score of 660 or higher. Her mom's score is in the low 300s. 
My tenant is obviously upset.

Answer

If her mother isn’t on the lease and your actual tenant is not in medical need of these repairs/upgrades then that’s a hard NO for me. I also would consider not renewing her lease as it seems like she’s trying to pull one over on you. I do not like people like that. If you have to get a lawyer, I’d also file that she pays your legal fees. Some people just feel so entitled when they don’t even know the law.

Answer

What tenant would expect a landlord to pay for all that?! If I were her, be looking at a house that accommodates my mom, not the other way around. She can't realistically expect a landlord to pay for that, especially so that her mom can move in with her. 
I wonder where her mom lives now.

Answer

I am not a lawyer, so this is not legal advice, but just by doing a Google search I have learned this… If her mother becomes a tenant, you will need to make effort to accommodate her in someway. But you may not have to do everything she is asking if it will cause undue hardship to you. Meaning, if you cannot afford to do all of these renovations, you may not be required to. As long as you make effort like installing handrails in the bathroom and maybe adding a ramp to the entryway, possibly widening doorways if possible. With that said, every legal tenant should be on the lease. She cannot legally be denied a roommate (depending on whether there is enough room for two occupants, overcrowding could be one reason to deny a  request for roommate). Her mother is not your legal tenant yet, so at this point in time accommodating for her is not your responsibility. You also cannot discriminate against a prospective tenant because of a disability. But every new tenant is subject to your approval, by whatever means you would do that. Whether it be background check, credit check, income requirements, etc. You are allowed to reject approval for any reason except because of discrimination (in this case against disability). Having her move in without your approval, could be a considered unauthorized occupant, and that is grounds for eviction. Additionally, you could raise rent if another occupant is in the unit. Definitely get some advice from a lawyer before saying anything to her about anything. I do not claim any of this to be 100% accurate as it just came from Google. ￼￼￼￼￼￼￼￼￼

Answer

Simply deny adding her to the lease and let your tenant know so she can look to rent elsewhere that already has what her mother needs.

Answer

Legally you can't deny her as a prospective tenant for her disability but you could do something such as tell your current tenant she can't add anyone to the lease for liability exposure so if she moved her in without permission or adding her no you would not legally be required as you can refuse her as a prospective tenant for any reasonable reason other than what would be deemed discriminatory.
