WestJet has a moderate fleet coverage of 55.5%, indicating a reasonable chance of Starlink being installed on aircraft operating this route. However, there are zero observed flights with confirmed Starlink on YLW->YYZ, so empirical data does not support a high probability. No recent airline-specific news is available, but a community sighting from a nearby route (YYC->YYZ) mentions ongoing rollout, suggesting some presence in the region. Given the lack of direct observations and news, the probability is conservatively anchored near zero but slightly increased to 0.10 to reflect fleet coverage and community sighting evidence.
