Job Search in Canada from US

I am considering a move to Canada (for reasons other than politics if you can believe that). I am just starting my job search and I am not exactly sure how the process is different than in the US, or what the job market is like for my profession.

I am a computer programmer. my most recent and extensive experience is with Java. I am currently working on a government grant designing mathematical software for use in education. Unfortunately the grant runs out in September. I have a Physics degree and experience in education.

I am most interested in working for a research group, preferrably either in science, math or education. I am also interested in small companies with innovative technology. Of course I would love to hear of any interesting opportunities in other areas.

I am already looking at the job search sites that pop up in Google. They seem (like similar sites in the US) to be centered on business type jobs that don't match my skillset.

I am planning to research Universities (which are often connected to research groups) and I am trying to find information on who is giving grant money, and for what programs.

I would really appreciate help with the following....

1. Any ideas on how I can get in touch with research groups, particulary in science or in education. If you can put me in contact with a person in this field, I would be forever in your debt.

2. How I can find small companies who are developing innovative projects.

3. Information on places I should look for organizations or small companies that would be of interest.

4. Any other hints on how to conduct a successful search in Canada.

Thanks
