Ok what now? China made its announcement on last Saturday and I see that the media is now carrying the edict;

China said on Saturday that it would suspend all tour groups and the sale of flight and hotel packages for its citizens headed overseas, starting on Monday. The association for China’s travel agencies said tour groups that were in the middle of their trips could proceed with their itineraries but should closely monitor the health of their travelers.

What will Air Canada's position be? AC has a JV with Air China and CA sold group travel on behalf of AC.

Forbes has clarified The ban is not on all outbound travel. The ban, first reported by Bloomberg, applies only to group travel and not passengers making their own arrangements, although the ban has the indirect impact of sending a message to an already cautious market.

Forbes also states that China’s aviation regulator ordered local airlines to offer refunds to passengers wanting to cancel travel. Foreign airlines are doing so voluntarily, but only for immediate travel: up to January 31 for American Airlines and Delta Air Lines, and up to February 7 for United Airlines. No mention of Air Canada, however as group travel on AC was typically booked through CA, this may not be a big issue. This legal order protects customers originating in China, but what of this in Canada? It looks like Canadian customers will not be treated as generously by Air Canada.
