What are the implications of Canada stopping the issuance of income letters for non-O visa holders in Thailand?

A notice has been shared indicating that Canada will stop issuing income letters as of April 1, impacting Canadian expats in Thailand who need proof of income for visa purposes. One expat mentions renewing his NON-O visa recently but is concerned about finding alternative methods for income verification in the future. The discussion highlights the urgency for Canadians to obtain income verification from the Canadian Embassy before the deadline and suggests that after April 1, alternative methods for proving income will be necessary, similar to requirements faced by expats from other countries.
