Residents, city workers, the military and emergency responders are working together to prepare for the flooding by digging dikes and installing walls of sandbags.
But if an evacuation order does come, it's critical that residents are prepared to leave, said Montreal Fire Department chief of operations Martin Guilbault.
That means packing a bag with clothes and other supplies to last 72 hours, lining sandbags around your home and considering moving any valuables out of your basement, he said.
There are about 50 troops in Île-Bizard, and another 30 on Île-Bigras in Laval, helping with preventive measures.

The SPVM will still be serving the island using police boats, but there will be fewer resources available to those who stay.

"We will be flooded as most communities will be," said Pierrefonds–Roxboro Mayor Jim Beis.
"But we're hopeful that with the tools we have in place we will minimize the impact to the population and that's our ultimate goal."
Sandbags are being loaded into trucks at Pierrefonds Comprehensive High School to deliver to at-risk homes.
Marie-Eve Ménard and her daughters were helping fill sandbags at Pierrefonds Comprehensive High School on Monday.
"They were really happy, actually, when we said 'let's go do sandbags,'" Ménard said.
Guilbault said the teamwork between emergency responders, residents and volunteers will make all the difference as the city prepares for more flooding.
"We're working hard, people are doing their part and together we're going to minimize the impact of that flooding on their home," he said.
Those needing assistance from the Red Cross can go to the Pierrefonds Cultural Centre at 13850 Gouin Boulevard W. from 10 a.m. to 6 p.m.

Volunteers working in the parking lot of Pierrefonds Comprehensive School have spent days filling sandbags and giving them to residents in order to protect their properties.

"Certainly in 2017 the extraordinary crisis that we had no one had ever seen before, and you learn from this type of events," said Beis.
"We started looking at ways of improving not only the infrastructure but also having the necessary equipment on site to make sure we deal with any eventual flood and Id like to say weve done this and up to this point successfully."
