There will NOT be a general announcement to all customers about the existence of a buffer zone or about the customer with severe nut or peanut allergies.
To request the buffer zone, you must contact the Air Canada Medical Assistance Desk (1-800-667-4732) at least 48 hours before your flight.

Crew will ask customers seated in the buffer zone to refrain from consuming any nut containing products they have brought onboard and will not serve any nut containing products to these rows.
On a recent JetBlue Mint flight, my clients, one of whom has a nut allergy, was helpfully given the ingredients list of all the dishes served in JetBlue Mint by the flight crew, who was also happy to leave off an allergy-containing garnish.
JetBlue will offer a full refund to customers for whom these conditions make it impossible to travel
