The 26-year-old Saint-Ferréol-les-Neiges native came in just behind Norwegian great Petter Northug.
Northug made a late burst to come from behind and win the 15K pursuit in 42 minutes, 1.2 seconds, edging Harvey by 0.6 seconds and Sweden's Calle Halfvarsson by 0.8.
Northug was third in Saturday's 4K freestyle race.
Harvey competed for Canada in both the 2010 Winter Olympics in Vancouver and the 2014 Winter Olympics in Sochi.
In Vancouver, he made history by finishing fourth in the team sprint with Devon Kershaw. That result was the best placing for Canadian men in an Olympic cross-country competition.
The tour next moves to Val Mustair in Switzerland for races on Tuesday.Suggest a correction
