Input appreciated as to where notice is to be provided to BA...I cannot locate an address for notice within the terms and conditions of the Executive Club. Below is reproduced from those terms conditions.

34.2 Canadian Residents

34.2.1 Canadian residents consent to have any Dispute arising from these Terms and Conditions resolved pursuant to the following procedure:

34.2.2 Notice and Negotiation. You will give British Airways notice of any Dispute arising from these Terms and Conditions. Following such notification the parties shall meet at a mutually acceptable time and place within 30 days after delivery of such notice and thereafter as often as they reasonably deem necessary to exchange relevant information and to attempt to resolve the Dispute. If the parties have not resolved the Dispute within 90 days of the disputing party’s notice, the parties may initiate mediation as set out below.

PS....I submitted a note online and specifically asked where notice should be given and I was told BA would not discuss the matter with me and file with CEDR which seems to be contrary to its own Executive Club terms conditions and may constitute a waiver should I be required to proceed under terms and conditions.
