I live in the province of Québec, Canada. In Québec we have rent increase laws that don't allow landlords to increase prices as they want. You can read all about them here. In a nutshell, landlords have to follow the increase index set by the rent tribunal. If they increase it more than the rate, tenants can fight the increase. That means someone who has been living in the same apartment for a long time like 10, 20, or 30 years will have a relatively low rent compared to newer apartment buildings. The only way you can really kick out a tenant is if you have relatives who are going to take over the unit. (A lot of landlords abuse this rule to kick people out, but end up in court when the previous tenant can prove the landlord's relatives didn't move into the unit.)

Alternatively, if you need to evict your tenant, and they agree, you have to pay for the moving & storage fees for their belongings, and pay for the difference in rent for 1 year. Most of the times, landlords will just give a lump sum to pay for these fees and they're often below what these fees would cost. The tenant can agree or refuse.

Some landlords, especially property barons, will use aggressive tactics, intimidate their tenants, hire muscle to harass their tenants and do everything they can to make their lives miserable, including throwing all their belongings out the window.

Typically this happens when someone buys the building to flip it for profit. They'll evict everyone, renovate with cheap materials and re-sell at an increased price. The new landlord will set the new increased rental price per unit as if it was a new building.

And when this happens, all the old tenants can't afford to live there anymore, and because of property price speculation and how rents have increased across the board because of these tactics, they end up not being able to afford rent anywhere and become homeless.

prices go up, kick out old tenants, landlord special remodel, rent for 2-3x the price to new people.
