When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 10 hours outbound, on a 7-night trip — ticketed under Porter Airlines Canada, which on a connecting fare need not operate every leg. At $601 for 5,634 km each way, that works out to about $53 per 1,000 km flown. That is above the $43 per 1,000 km typical of medium-haul fares here. Across the 7 departure cities we track at a similar distance from Porto, this fare ranks 2nd — 19% above the $503 from Dubai. That puts it in the cheaper half of the 26 routes of similar length we watch out of Toronto, where the middle fare is $621. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Porto: May–Jun · Sep–Oct.

The median cached fare across this calendar is 6% lower than when tracking began on 8 Aug — $792 then versus $741 now, across 17 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $446, on 1 Nov.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
YTO → OPO, answered.
How far in advance should I book YTO → Porto?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Toronto to Porto?
The current cheapest fares involve a connection, ticketed under Porter Airlines Canada. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
