Its in Newfoundland Canada, so yes, there is PST and GST which are like VAT at both provincial and federal levels. usually works out to a 14% add on. If you are a Canadian there are ways to write it off on your tax claim, but that would be very specific to your case. usually you just have to pay it....

The other thing about this company, that is more my opinion than anything provable by fact, is, I have never trusted any company from my country that uses the terms "Great White" "Great Northern" or "Great Canadian" in their title. Every single professional service that I have ever dealt with that hides behind this sort of entry level nationalism and cheap flag waving has proven to be bullshit. that's been my experience, there may be exceptions, but flag waving and thumping chest whilst shouting "Canada Number ONE!" just screams bullshit smoke n mirrors to me. Canadians have the unfortunate habit of thinking they are better than everybody else whilst being mostly below average, boring, small-minded and weak. be careful, Canadians are the worst sort of bullshitters, they are bullshitters who are convinced they are righteous honest and correct.

of course, this company is in Newfoundland, so technically, they aren't even Canadians, they're more like mutant donkey versions of newly landed immigrants. sub-normal at best.

We only payout in coins that we mine and with the current scrypt hashrates, we're not mining LTC... There were some payouts that went through after the xpool migration, but that it about it.

from the main page:

Non-BTC payouts depend on that coin being mined as your BTC balance is traded internally by our system to your currency of choice. If we have not or are not mining that currency your payouts will be delayed until the pool has mined the blocks for you to get paid. If you notice in the pools status that the currency is red, it means there is not sufficient amount of the currency to pay miner(s). It's recommended to use BTC as any other coin could be removed at anytime and payouts will not occur.
