>Why is the site called "Leave Canada Now". Is that a threat to the Canadian government that you will leave Canada if this is not resolved?

It represents the reality that Canadian Internet entrepreneurs can no longer do business in Canada.

In summary:

A New Brunswick company, known as Level Extreme Inc., has been fighting the Canada Revenue Agency for the last two years in regards to a Canada Revenue Agency Ruling forcing it to tax its international customers. This ruling has jeopardized and harmed the administrative operations of a Canadian company, which by the same, has removed its capabilities to compete equally against other international companies in the same business. It is unacceptable that Canadian companies are forced to tax international customers with an insulting Canadian tax. If the Canada Revenue Agency does not adjust accordingly, Canadian companies doing e-commerce business or ones with the desire to do so would have to leave the country in favour of offshore setups.
