Hi there!
Welcome 
It's so nice to hear your kind words about Canada. You didn't mention which province(s) you visited while you were here, so I'm not quite sure where your interests are.
I've lived in Nova Scotia (East Coast island) on the Atlantic coast, which is rocky, full of lakes and forests - absolutely breathtaking scenery. From my experiences, the people are friendly to visitors, but not so much to newcomers that are moving there. The locals are not big fans of change.
I've lived in British Columbia (downtown Vancouver). You get the best of both worlds there. Mountains to one side, and the ocean on the other. Plenty of activities there no matter who you are. There are all types in BC and you will surely find an area that fits you well. Unfortunately, a lot of the downtown residents have become a little bit snotty and materialistic (the 20-30 somethings), but for the most part everyone is great. I really don't have anything too negative to say about this city.
A quick sidenote before I continue: I've lived in England as well (known for the amount of rain they get there)...Well, it doesn't even compare to what we get on the East and West coasts of Canada. Nova Scotia outweighs Vancouver and London - hands down!
Currently, I am living in the province of Ontario (downtown Toronto), which is pretty central. Toronto is where all the jobs are, and a lot of the action is. It's a wonderful city with so much to do. Unfortunately most of that is man made - if you're a nature lover, you may want to consider Northern Ontario or head toward one of the coasts. Beware: The summers in Toronto can be insanely hot and humid and the winters are wickedly cold!
I'm not sure what else to say. This is a massive country - it took me 9 days to cross it by car - but I have visited a lot of places and would be more than happy to help answer any other questions or assist you with your research. Feel free to post again or send me a direct message.
