Our Member Service team works behind the scenes to make sure you get what you need. Located in our St. Catharines community, our Member Service Centre Representatives are often the first point of contact and if they can’t personally take care of your needs right away, they will connect you with the right person who can.

Our Member Service Centre is available during the following hours:

Monday to Friday 8:00 AM to 8:00 PM
Saturday 8:00 AM to 5:00 PM

You can also check our availability during holiday hours.
