You should consider calling the City of Toronto to file a complaint with them. There are two main department that might be helpful – Toronto Public Health, and “Rent Safe TO”.
Public Health can send a health inspector to view the status of your apartment, and their inspector has the authority to order your landlord to do things, so the complaint to make with them is that your apartment is unhealthy (dusty, poorly maintained, do you have any holes in your walls?).
RentSafeTO also has inspectors, and they can issue orders and fines to Akelius, and they enforce some rights that you may not know that you have. In particular, check-out this webpage:
https://www.toronto.ca/community-people/housing-shelter/rental-housing-tenant-information/rental-housing-standards/apartment-building-standards/rentsafeto-for-tenants/On that webpage, click on the section: “Making a Service Request to Your Landlord”, which explains that landlords have to respond to urgent maintenance requests within 24 hours, and all other maintenance requests within 7 days. (Unfortunately, lots of tenants find that RentSafeTO is a bit of a “black hole” with respect to tenant complaints – they are frequently ignored, so you might have to pester them to do their job and help you. But if you have the time then it can be worth it.)
Both Toronto Public Health and RentSafeTO can be reached by telephoning “311” or e-mailing: 311@toronto.ca
