Would you burn this bridge?

I already accepted a one-year-long rotational investment banking analyst program at one of the largest multinational banks in Spain. The background check and everything has already been completed, and I am about to start next week. At the end of this program, I would have the opportunity to apply to permanent positions at the bank. 
 

However, I just received an offer for a permanent full-time M&A analyst position at one of the largest 5 Canadian investment banks. In this role, there will be no rotational aspect, and I would be covering only the Media & Telecom industry. I would not be covering technology. 
 

In terms of training provided, I think the one year rotational analyst program would provide a more formalized training as I will be joining an analyst class rather than joining as a lone analyst. However, I believe that the rotational analyst program is more focused on capital market transactions (origination, syndication, execution, etc) than it is on M&A. Not completely sure about this though.

And in terms of compensation, in the rotational analyst program, I would be earning around $38 per hour between 9 am and 5 pm and around $57 per hour during other hours. I won’t be eligible for bonus. At the Canadian bank, I would get a competitive base salary and bonus. 
 

In terms of long-term career prospects, which would you choose and would you burn the bridge?
