In fact, when determining whether something is under provincial or federal jurisdiction, we have to look at the facts. First of all, freight airlines, technical service providers and ticket providers provide related services. The bill defines what air services are, and what related services are. Ticket purchasing is a related service. Thus, we consider it clear that Air Canada's online activities are essentially online ticket reservations.
Air Canada Vacations however is really a travel agency. Travel agents come under provincial jurisdiction, unless they are a company division. If Air Canada Vacations was an integral part of Air Canada, and was a division of Air Canada, then the Official Languages Act would apply to it. However, given the nature of Air Canada Vacations' activities and given the fact that it is an entity separate from Air Canada, then it comes under provincial jurisdiction and the provinces are responsible for enacting legislation governing Air Canada Vacations' labour relations or languages.
