Canada Helps is a Canadian organization that allows for fundraising for registered charities whether they have a webpage or not. They do take a small processing fee, but they are easily accessible whether your church has a website or not. (Fee link https://www.canadahelps.org/en/why-canadahelps/our-fees/
Once you register for free within their program, you can be searched on online and donations may start. Once registered you can of course arrange for a link to your website if you have one. You will notice that the ABT Synod has a Canada Helps link on the bottom panel of our webpage.
Does your church already have an account through Canada Helps? Check and see at https://www.canadahelps.org/en/.
