Problem with geocoder search city

Hello everyone,
I use google API geocoder to find places here in Canada

In my research, I do not always get the same results
BY example if I seek the city that London is in Canada, I receive Londopn of UK

Here is an example of the API I speak:

http://gmaps-samples.googlecode.com/svn/trunk/geocoder/singlegeocode.html

I wonder if there is a method to specify the country

thank you

Hi I don’t know the method off hand but an app that I worked on about a year ago reliably found Canadian locations. I know three were a couple of different methods/techniques to specify country.

In my research we can use:
LatLngBounds
or define:
The Latitude and Longitude of Canada is 60° 00 N and 95° 00 W.
but I can find no solution yet
