What are CANADA POST delivery method?

It's my first time receiving a package from EBAY. The item will be shipped through USPS then it will clear customs then CANADA post will deliver it to my house. THE seller said it will take a week. I live in an apartment so what I want to know is if they require a signature. I also want to know if I'm not home at the moment where will they take the package.

Thank You very much in ADVANCE!
