If you're pledging to the United Way (or All-Charities in Manitoba) through your payroll deduction, do consider the Ukrainian Canadian Foundation of Taras Shevchenko.
Here is the link to the CRA website: http://www.cra-arc.gc.ca/chrts-gvng/lstngs/menu-eng.html.
Just type in their name - Ukrainian Canadian Foundation of Taras Shevchenko - and it will take you to the registration number.
If you have any questions or difficulties with the online procedure, call Halyna Kinasevych, Executive Assistant of the Shevchenko Foundation at (204) 944-9128, send here an email.
Your generous donation will provide a lasting gift to Canada's Ukrainian community.
If you're not familiar with the significant contribution the Foundation makes to Canada as well as its Ukrainian community, you can get a good overview at their website.
