While the relation between the issues at stake and Poëti idea to move the event isn't clear to me, the journalist of the linked story does it. To summarize, La Presse reports that Six Flags now appears in the lobbyism register to renegociate its long-term contract with the City, more specifically to decrease rental and to revise the provision regarding the Montreal International Fireworks Competition.

La Ronde spokesman does not provide explanations, but is quoted to say that La Ronde hopes to hold the event for years to come. Registration has been done last Friday:

I wonder what are the specifications outlined in the contract regarding the competition. Are there specifications about the number of shows per year, the dates, or the competition concept itself? The Quebec City fireworks event is no longer a competition since 2013. However, as far as I remember the information released at the time, Six Flags had engaged, in 2001, to hold the competition for 10 years only.
I imagine that it may be challenging for Six Flags to negotiate a decrease of its rental, as the company can't threaten to move its amusement park to another, less expensive, location. However Six Flags may bring the following argument. Assuming that City of Montreal hopes that an international fireworks festival continues, Six Flags can argue that growing economic pressures make it more difficult to hold the event, so a decrease of its rental would help to continue it; whether the City doesn't agree to reduce the rental, the City would have to take the blame for the end of the event.
Beyond the actual cost of the event (which most part is covered by sponsors and public funding), Six Flags may even argue that holding the competition has a huge opportunity cost, as a significant portion of the land is monopolized by the competition, that is, for less than 30 hours of use per year. To terminate the fireworks competition may bring opportunities for more attractions around the lake (and even where the lake is located, as its size may be reduced), such attractions being the way to increase current or future profitability. Therefore, Six Flags would engage to continue the fireworks competition in exchange for a decrease of rental.
A more Machiavellian scenario is that Six Flags' longtime goal is to terminate this event and engages into this bargaining without the genuine intent to continue the competition. So the current negociation would be the ultimate mirage to achieve this goal.
I am afraid that the Montreal International Fireworks Competition may be jeopardized like never before.
