My best advice to you regarding a trip to Canada?
Don't base yourself in one spot, Travel as much as you can.
Toronto is a holiday experience in itself. Niagara, well I'm sick of seeing it but, It's probably the most spectatcular sight I have ever seen, The helocopter ride over the Falls is just amazing.
I recently had a couple of cousins from Luton and western super mud and, they were doing the travel thing from New York - Toronto - Clagary (For the train, through the rockies all the way to Vancouver). They said the whale watching in British Columbia was a life time experience.
If you end up in my neck of the woods, It would be nice to put a face to the name, have a barbie and drink some Canadian beer.
Make sure though that, you research a trip to Canada and make sure you get the best package with the best and most suitable flight that suit your budget and time scale.
Me, well I tag along with my wife and two boys to the beach most days of the summmer. Since I work shifts, I take a few hours in at the beach before I get to work. I never thought I would be doing that when I lived in Glasgow, how things change EH?
