Yeah it's really shitty, check out the law on contest and sweepstakes Quebec (and the other locations) has and you'll understand why everybody excludes the province.
If it was only Quebec it might be doable for significantly bigger contests where the extreme time and energy needed to be compliant could be justified, but there are other locations mentioned above who have similarly (yet different) strict laws which makes it impossible to accommodate it all.
It 100% makes sense to be angry but you should be especially angry at the province and the turds who passed these laws 
There are always ways around it if you have friends or family outside of the province who could receive the prizes for you...
