Most valuable sports franchises - where is Canada?

Today, I came across an analysis of the most valuable franchises in sports, which makes quite interesting reading.
The top ten (in 2017) are:

• Dallas Cowboys (NFL): $4.2 bn
• New York Yankees (MLB): $3.7 bn
• Manchester United (European Soccer): $3.69 bn
• Barcelona (European Soccer): $3.64 bn
• Real Madrid (European Soccer): $3.58 bn
• New England Patriots (NFL): $3.4 bn
• New York Knicks (NBA): $3.3 bn
• New York Giants (NFL): $3.1 bn
• San Francisco 49ers (NFL): $3 bn
• Los Angeles Lakers (NBA): $3 bn

The rest of the top 50 continues in much the same way, dominated by the National Football League (NFL, which comprises 29 of the top 50), Major League Baseball (MLB, 8 of the top 50), National Basketball Association (NBA, 7 of the top 50), and European Soccer clubs (7 of the top 50). Interestingly, to a Canadian at least, no National Hockey League (NHL) teams made the top 50.
Just for comparison, Canada's most valuable sports franchise, the Toronto Maple Leafs (NHL) is worth about $1.4 bn, followed by the Toronto Blue Jays (MLB) at $1.3 bn, Toronto Raptors (NBA) at $1.1 bn, and Toronto FC (MLS) at less than $0.3 bn.
