In recent weeks, we have seen a heightened level of concern related to the spread of novel coronavirus (COVID-19). We recognize that this may be an unsettling time and want to assure you that BMO is taking action to safeguard the health and well-being of our customers, our employees and their families.

We are currently prioritizing assistance for card members who have travel bookings scheduled within the next seven (7) days. If your travel plans are more than seven (7) days in the future, we appreciate your patience as we focus on customers with the most urgent travel needs at this time. Card members with travel plans within the next seven (7) days are encouraged to contact the Club Rewards Call Centre at 1-800-234-4034 for assistance between the hours of 9 a.m. – 9 p.m. Eastern, seven (7) days a week. 

For the latest cancellation or change policy information, please visit the airline or other travel service provider’s website directly.

Service is our hallmark. Rest assured.

We're ready to help — whether you're at home or traveling abroad.
