canary are fairly easy upkeep
they need to be kept in a good sized cage (the cages often sold for canaries are tiny, they are active little song birds who need some space.) with some interactive toys and lots of natural perches.
kept away from drafts, they like it bright but shouldnt be kept in direct sun either, they can overheat if in direct sunlight.
they are generally content being a lone bird, though kept in groups males will still sing.
they generally do NOT enjoy being handled (even if hand fed) some can become "tame" but most are simply "cage birds"
depending on the type of canary the voices are different, but most males will warble and sing all day, as soon as things start to go down the will settle for the night.
female canary dont sing much at all....and some males also do not sing! (a mirror will help encorage singing as will lots of bright light and a good cage setup)
their song isnt super loud, a canary will not generally bother neighbors ect, and most apartments will have no issues with a canary...
there not what i would consider "noisey" they make peeps cheeps, chirps and warbles, they do not scream like parrots do.
they should be given fresh water frequently, fed a good quality seed based diet (song birds are seed eaters. and red colored birds are usually given a red dyed food (like egg food) to keep their colors bright.
they can live a farily long time for a small bird.
