How the days are counted

183 days of sojourning in the calendar year make you a deemed resident for the whole year, on worldwide income and with no part-year proration. Any part of a day counts as a day. Someone who crosses to work and goes home to sleep outside Canada is not sojourning, but the same person on holiday there is.

This rule only applies to someone who does not already have enough ties to be a factual resident, so the count does not decide on its own.
