UK buyers include representatives from Informa, Eurofinance, Clifford Chance, Zibrant, Grass Roots and Universal World Events.
Delegates from the rest of the world include American Express, Allegria, Proske Group and Together.
Buyers are meeting with representatives from Fairmont, Raffles and Swissotel properties from around the world and Canadian tourism representatives, and will be taking part in activities and staying at Fairmont properties in Montreal and Quebec.
Meenaz Lilani, executive director of global sales for EMEA, said: "We wanted to give people the opportunity to experience a destination as well as a business reason to come, giving them the opportunity to meet with our hotels and discuss their needs.
"We chose Eastern Canada, because it’s an easy to get to destination and many people from Europe just consider it. But it’s within very easy reach and has a real affinity with Europe."
