I would say there is a very very low plausibility of it coming close to those cities from a earthquake triggered tsunami, if there were a asteroid impact near the northern part of the gulf then I would say it is plausible. However you are writing a sci-fi so it can be as outlandish as you wish.
There are earthquakes going on in the Canary Islands by El Hierro..(.not certain I spelled that correctly) and if/when it sinks into the ocean like they are expecting it to, there will be about 8 hours until a tsunami reaches the east coast (including Nova Scotia) and for about 200 miles inland everything should be covered with water. My daughter, son-in-law and grandchildren live in Nova Scotia so I am always watching this... http://www.youtube.com/watch?v=TU7joxqEQ-w&feature=player_detailpage#t=0s

Isnt Montreal and Quebec farther than 200 miles?
If the tsunami happened than rivers would also be flooded is the point, so even more places inland would flood
There is always a chance of some people being draw into some YouTube hoaxes, pseudo-science and just plain nonsense. The Indonesian and Japanese tidal waves were caused by earthquakes in the subduction zone of colliding plates. Triggered by large vertical movement of the ocean floor. There is no subduction zone off the East coast of Canada. In fact there is no major subduction zone in the Atlantic (North or South). Ruling out for the moment a tsunami caused by an asteroid impact the chances of Eastern Canada suffering a major tsunami is highly, highly, highly unlikely!
The Indonesian tsunami reached a maximum height of around 15m and the Japanese tsunami 10m. Most locations experienced heights much less than these maxima. Should a tsunami reach shore at the mouth of a river it would travel upstream. The amount of water moving inland is constrained to the amount that enters the mouth of the river. So the mouth of the river restricts the volume of water that can move inland. The energy of the tsunami would be quickly dissipated although there would be a noticeable bore (a wave that travels upstream). Damage inland away from the mouth of the river would be very limited except in extremely low lying areas.
YouTube is unique in that it can be informative, it can be entertaining and it can propagate sheer BS. So please try to be objective when exposed to some of the BS on YouTube.
ICRCC, Thats what I was thinking. The mouth of the river as well as any turns in the river . Aren't tsunami's lifeblood a straight trajectory?
Yes they are just a wave that spreads out from the point of origin. Like a stone being thrown into a pond. The only increase in volume of water is n the wave. So only that amount of water entering a river mouth would be free to move upstream. You are right that every twist and turn in the river also every time the river widens would dissipate the energy of the wave quite quickly.
It seems to me that the east coast isn't what anyone should be worrying about. Now our Pacific coast is another matter. Sitting on a fault as it is that runs all the way down to California, I think it's a matter of when and not if. I'm not a fortune teller and don't have an idea for the when of it. It could be 200 + years down the road. I'm not buying recreational property in Bamfield in the off chance it's sooner.
Needs must when the devil drives.
You are right Antsy, the West Coast of Canada is entirely another story. The intervals for the last 13 major geological events (massive earthquakes with accompanying tsunamis 5M to 10M high) range from 300 to 900 years with an average of 590 years. The last major event was 1700AD. So we may indeed have another 200 years before the next one. However If you consider the entire west coast of North America there have been 40 catastrophic earthquakes during past 10,000 years. That means that the region experiences an earthquake, having a magnitude of 9.0, every 242 years. The last major event was 312 years ago, using this approach the West coast is overdue by 70 years for a massive earthquake! Let's hope we have another 200 years.
