The Oilers' quest of a sixth Stanley Cup title could put them in direct conflict with the Dora the Explorer stage show set for Rexall Place June 17.
The NHL, however, has scheduled Game 6 of the final that night should the series go that far.
Northlands Park was aware of the potential problem when the NHL released its schedule Tuesday.
Northlands Park runs Rexall Place, the arena the Oilers play in.
Spokeswoman Bonni Clark said the NHL, Rexall Place and organizers for the Dora show are working to find a solution for all parties involved.
This is the second time the Dora stage show has affected the NHL's playoff scheduling.
During the second round, the Ottawa Senators were forced delay Game 2 against the Buffalo Sabres because the popular show was scheduled for Scotiabank Place on May 6 and 7.
