>>>not quite sure what type they are but i know that they are called swamp
cedars....does that help?
i live west of montreal, <<<

It helps immensely.  Swamp cedars are "Eastern arborvitea" scientific name
"Thuja occidentalis"

>>> st. lazare...sandy soil,  not sure of the acidity,
but they did really great this year...except for now...they do look better
today though...could it have been the massive amounts of rain or could it be
that it is getting colder at night.?>>>

They are subject to the following diseases:
Leaf blight...one to more than three irregular circular brown to black
cushions on the tiny leaves in spring.

Juniper blight...

Leaf browning and shedding... older inner leaves turn brown and drop in
fall.  A natural annual phenomena that can be sudden (in a few days and
therefore noticable) or gradual (over weeks or months and not noticable)
depending upon the growing season.

Winter browning... caused by rapid temperature changes in late winter and
early spring.

I'd suggest that the hurricane rains might have created a sufficient shock
to the plants to cause them to temporarily shed leaves. Keep an eye on them
for insects and see if the problem seems to persist or worsen.  If not, then
that's probably what it was.
