Best Time to Book

San Francisco → Toronto flights

Median SFO–YYZ fare is $196 over a 12-day sample; most fares fall between $187–$204, so timing shifts the price only modestly.

SFO–Toronto fares cluster near $196 — spread's modest

Key takeaways

Median fare sits at $196, with a tight bottom quartile of $187–$204
Low end of the range hit $156, but that appears to be an outlier rather than the norm
High end of the sample tops out at $204, meaning most days cluster close to median
31% spread is meaningful but not extreme — this isn't a route with wild price swings
Sample is thin: only 12 daily snapshots, so treat patterns as directional, not definitive

The full picture

Based on 12 days of fare snapshots, SFO–Toronto pricing looks fairly stable: the median sits at $196, and the bottom quartile (p25–p75) spans just $187–$204 — a tight band suggesting most travelers will land near that median regardless of exactly which day they book. The $156 low is the standout exception in this dataset, sitting well below the p25 mark, which hints at a one-off deal rather than a repeatable pattern.

With a 31% spread between low and high, there's some room for savings if you catch a dip, but this route doesn't show the dramatic booking-window swings seen on more volatile itineraries. Because our sample only covers 12 days, we can't confidently point to a specific booking horizon — a 60-day-out versus 14-day-out comparison isn't available here. What we can say is that the bulk of observed fares held in a narrow $187–$204 range, so budgeting around $196–$200 is a reasonable baseline expectation rather than hoping for a steep discount.

No dominant carrier or day-of-week pattern is visible in this dataset, so we won't speculate on either. The honest caveat: with only 12 snapshots, this is a thin sample for a route-level pricing story — enough to describe the current price band with confidence, but not enough to make strong claims about seasonal trends or the ideal time to purchase. Treat the $196 median as a solid reference point, and watch for outlier drops like the $156 fare, but don't expect this route to behave like a high-volatility market where booking timing swings the price by hundreds of dollars.
