Thanks for contacting us! In answer to your questions:
1. Your credit card payment will be completely secure. Our payment provider is Braintree. Owned by PayPal, and used by such well renowned companies as AirBNB and Uber, you can feel confident that your information will be safe.
We also offer the ability to upgrade using PayPal. This way you don’t actually have to share your credit card details with us, and simply upgrade using your PayPal account.
2. The cost for 1 year is US $29.95. Your credit card will actually do the conversion to CAD, however you can use this tool to see the current exchange rate, which will give an excellent indication of what the charge will be.
