Lacey can't get from Regina to Toronto because it is "completely snowed in". It makes no sense that she could get there from Calgary (or Edmonton), the two options she runs into as her travel plans continue to push her off track.
When Wanda is speaking with Lacey on her bus from Calgary to Edmonton and Wanda realizes Lacey keeps getting farther west, she says it will add "40,000 kilometers" to her trip. That is an obvious exaggeration, since Toronto is less than 4,000 KM from Edmonton.
