I can now report that the transfer was processed in 53 days, with no apologies from either LAN or SPG. I will advise SPG that they should change their documentation to reflect realistic timelines. After waiting over 40 days, I eventually had to give up and buy a ticket. I completed my YYZ-LGA round trip yesterday and am now stuck with 16,000 km in my LANpass account with no plans to take a short haul before they expire.
