Where I am in British Columbia, there are sound isolation requirements in the building code so the landlords can't be cheap...but it doesn't help with older or non-permitted work.
A quick google suggests that British Columbia's building code only requires STC 50 which is "you can hear but not understand a neighbor's loud conversation" levels of isolation. Though maybe your city has stricter requirements?

STC 50 is a common requirement in the US too.
