Premium Aquatics Ships to Canada, at least they did.
redfishbluefish )I got some nice blue ridge rock back in the day or rather a friend said he got it there for me..., I believe it was them,, but I do know they USED to at least have liverock other than what you'd find at jl) Have not checked for a long long time.
ReefAquatica does as well I believe.
Aquavalley does I believe...
Someone once told me raging reef does, but I never looked into it...so don't quote me.
It's been a long time since I had a tank, and a lot of the places i used to go...well they seem not to exist anymore
you can go through the hassle of permits, I believe the cost they quoted me...a few years ago for a CITES permit was 200 Dollars, then you add freight on top of that which was 4-5 times the price for Canada...
if you have the money might be worth it.
My info is dated with regards to the above, but it's a starting point for you I hope.
