1. “3” → “three” & “1” → “one”
• Numbers below 10 should generally be written in words in formal writing.
2. “charities” → “charity”
• Since you’re referring to one Canadian organization, “charities” should be singular for proper parallel structure. However, if you mean multiple Canadian charities, “charities” is fine.
