The so-called 'residency' requirements for Canadian citizenship is strictly speaking a physical presence test.
Legally speaking, if you can prove your number of days within the past 5 years, and you satisfied income tax filing requirements for 3 out of the past 5 calendar years (not including the current one since you cannot possibly have filed your taxes for the current year), then you satisfy the 'residency' requirements.
However, because of your situation of not being employed in Canada, they may choose to scrutinize your application a bit more than other more straight forward applications.
Having strong ties definitely help, but only in so far in proving physical presence.
If you don't have the number of days (which is 1,096 days out of the past 5 years), it wouldn't matter what other 'proofs' of residence you show, you can't satisfy the physical presence test.
Before Bill C-24, the wording was ambiguous enough that some people were able to get citizenship without having accumulated 1,096 days of physical presence, provided they were able to prove 1,096 days of 'residence'.
This would be a situation where ties would matter, since being a resident is not necessarily viewed as exactly the same as physical presence.

Nowadays, they explicitly mention 'physical presence', so gone were the days where you could argue to have lived in Canada for 3 years, even though you were physically present for a little less.
