Other mistake: When Wallace is listening to the old voice mail message from Megan, it shows Megan's phone number as 416-555-0977. When Wallace looks at the phone number that Chantry gives him, it's the same number - 416-555-0977.
Continuity mistake: When Chantry is in Dublin writing her list, the list reads: Toronto - My Job - My Family - My Friends - My Life - Wallace. In the next shot of the list, it just reads: My Friends - My Life - Wallace. The first three entries on the list disappear.
