I would like to clarify a few things, since the commissioner will be here Thursday.
The official languages regulations set out the obligations concerning services to the travelling public, at airports, train stations, etc.
With regard to major airports, if we add the number of passengers arriving and departing, and it equals one million or more, services must be provided in both languages. For smaller airports, it depends on whether demand for services in the second official language represent 5% of the overall demand.
At border crossings, it depends. In New Brunswick, Quebec and Ontario, it depends on demand for services at each crossing. If demand reaches or exceeds 5% of overall demand, services must be provided in both official languages.
So, the criteria are quite easy to identify. In airports, services are offered in both official languages when there are one million or more passengers or when demand represents 5% of overall demand by travellers.
