is surprisingly quiet about their ability to issue charitable tax receipts for donations. Given how tight budgets are in the orienteering community, I'd expect them to pester us but they never do.
"Orienteering Canada will mail or email you a tax receipt. Orienteering Canada is a Canadian Registered Amateur Athletic Association, as defined under the Income Tax Act, and as such is able to issue tax receipts to people (individuals and corporations) making donations to the organization."
There are several ways to donate to Orienteering Canada
I expect OUSA has a similar status but I'm not familiar with that.
Any other organizations that adventure athletes might consider supporting?
