Am coming from Rhode Island
Would anyone know of any drawbridges over the Saint lawrence seaway ?
Am planning trip to Maxville ...

This is Maxville, Ontario, a village near Cornwall?

and a relative of mine who would like to go but is scared of heights
especially those high suspension bridges.

Nasty things, phobias.

All three crossings over the St. Lawrence into Ontario involve suspension
bridges. The Niagara River crossings are not, and the one at Buffalo
(the Peace Bridge) is relatively low; but traveling via Buffalo would
add many hours to the trip. The shortest route around the end of Lake
Ontario, the QEW, also involves high bridges over shipping channels at
St. Catharines and Hamilton, although these are not suspension bridges
and you can avoid them by taking a longer, slower route. On top of that
you'd also need to cross the Hudson River valley, or perhaps run around
the end of it to the north; if you take I-90 it's a high bridge but not
a suspension bridge.

Perhaps someone more familiar with the Montreal area than me can say
whether it's possible to cross the St. Lawrence there without using a
high bridge; I see from the map that one channel of the river has a
tunnel under it, but I don't know which or how many channels are used
by big ships that require high clearances. If this is possible it would
probably be your only choice by road.
