Yes you'll get sponsors if you first build a resume ... & there are some tough climbs in Canada ...quit the smoke & push ur body ...

and test these first ...

U need 3-4 years of strength,stamina & endurance building...lead a disciplined life...
then go for couple of less expensive major peaks to build ur resume to be accepted even with 70k to burn

...if you do that there will be ppl to sponsor...it'd depend on your pr skills

I don't have that much in me ...don't know but may be I too will give it a try...
nevertheless conquering Canada life will be not less steep and will be pretty tough a challenge to give the kick
