Flying to Honk Kong to catch a cruise ship..need a visa?

We are both Canadian citizens and residents over 70 years old going on a 28 day cruise with HAL. We leave Regina Sk on November 8 and land in Hong Kong November 9..we have a hotel (Cordis ) booked for 2 nights before we board the Westerdam ship on November 11..sailing out on November 12. Do we need a tourist visa? Our nearest China visa centre is a 10 hour drive from us in Calgary Alberta. Can er use the postal service or just we make a personal visit? Our cruise doesn't make any stops in China other than boarding in Honk Kong.
