Canada Trip

Hi everybody,

Juli 2012 will be a special birthday and I'm looking for a special 5-6 weeks push bike tour round Canada.
This is what I prefer to do:

500 km/week
more flat than steep
picking up me tent only on campsides
daily food-shopping must be possible
easy getting there from an international airport

Please tell me your ideas, internet links and literature advises.

Thank you

Ingrid
