Use an Egg Donor Agency
There are quite a few Facebook groups and other places online people can go to connect with potential egg donors. This can obviously be risky in terms of potential scams and other issues. Keep in mind, in Canada it is illegal to pay for egg donation beyond any out-of-pocket expenses associated with the donation, so there must be absolutely no mention of payment or compensation in the post. Use extreme caution in general when exploring this as an option to find a donor egg and do your due diligence.
