If you want to stay even longer, you'll generally need a residence permit or a long-stay visa arranged in advance — overstaying the tourist window is taken seriously even where entry is easy.
Overstaying in Canada — even by a few days — can mean fines, being flagged in the immigration system, and trouble on future entries. Some countries also bar re-entry for a period proportional to the overstay. The safe play is simple: count your days from the entry stamp (not your booking dates), set a reminder a week before your limit, and if plans change, deal with immigration before the deadline rather than after.
Sometimes, but not reliably. Immigration officers can refuse entry if your passport shows back-to-back tourist stays that look like de-facto residence. One or two re-entries per year for genuine trips are normally fine.
No advance visa or authorization — for tourist stays, your US passport is enough. Just mind the passport validity rule above.
