To be eligible for Canadian citizenship, you must have physically lived in Canada for at least 1,095 days (3 years) in the five years before applying. These days do not have to be continuous. You may also count some time spent in Canada before becoming a permanent resident (as a temporary resident or protected person), which counts as half-days—up to a maximum of 365 days. IRCC recommends applying with more than 1,095 days in case some days are not counted. You must also have filed income taxes for at least 3 of the last 5 years.
