Welcome to the community!
Sadly, no they are not included with pre-order of the S10 or S10+. The different providers offer their own promotions. Fido offers additional trade-in value when getting a new 2-year term.
I am quite disappointed that Samsung Canada has not included the Galaxy Buds in their promotions either. There are many other regions (including Samsung US and Samsung UK) which have included the buds as a part of their pre-order promotions, but Samsung Canada has not. They claim it's because the promotion is customised for the Canadian market. Personally, it's a pretty dismal promotion as there is absolutely no incentive for me to pre-order.
Not what you wanted to hear, but hope it helps
