Vrat / Satyanarayan puja on the day Purnima prevails at local midday; Snan-Daan on the Udaya-tithi day.
The Moon is at full strength on Purnima — its influence on the mind (Moon) is intense, hence the vrat's restraint and the Moon arghya; the most auspicious day for Vishnu puja and the Satyanarayan katha (Skanda Purana, Reva Khanda) — the katha may be held on any day but Purnima and the Sankranti are best; the fruit of the Purnima bath (Ganga-Yamuna-Narmada) and charity is multiplied.
The vrat rule: the Purnima by the udaya tithi or moonrise-vyapini — the fast on the udaya tithi day, the Satyanarayan katha and Moon arghya on the evening when the Purnima is present at moonrise (usually the same day; sometimes a day earlier — the list above follows the udaya rule, choose the katha evening from the tithi window); paran after seeing the Moon or the next morning.
13 in Canada (Toronto). Lunar months do not align with the calendar year, so the count can be 12 or 14.
4 of the 13 dates differ from India for Toronto, because the tithi is judged at the local moment (sunrise/moonrise/Pradosh) and Canada is hours away from India in time.
The katha may be held on any auspicious day (housewarming, wedding, birthday, the fulfilment of a vow) — but Purnima, the Sankranti, Ekadashi and Thursday are best; on Purnima both Vishnu-Lakshmi and the Moon are strong; if one has vowed a monthly katha, on the evening of every Purnima; if there is no priest anyone in the family may read it.
In the Satyanarayan katha the prasad is 'savaya' (sava pav/sava kilo/sava paanch) — a little more than the whole — a symbol of gratitude and increase; in the katha the merchant Sadhu suffered for forgetting his vow, hence the vowed prasad is savaya; the measure of the panjiri (semolina-ghee-sugar-banana-Tulsi), the panchamrit too is sava.
Yes — there is no rice ban on Purnima as on Ekadashi; fruit in the vrat (fruit-milk-sabudana-makhana), kheer-poori-sabzi-rice after seeing the Moon; waterless only for the healthy and vowed; the prasad (panjiri-panchamrit) first.
