Toronto
Re: As long as your donation is not different :)
Since $350 CAD is roughly equal to $289 US (at today's exchange rates), I am sure you would be very happy to get $350 US!!
I look at it this way, when a date is paying in USD in Canada they are paying me because as they stated they don "want to deal with exchanging it if it can be avoided." but that means the burden is on me to do so. My time, energy, and effort goes into that so the cost of all that is being paid for. I am happy to exchange the funds at my bank and on my time after our date but my date must realize that it is the convenience that they are paying for, if they chooses not to then I am happy to accept payment in Canadian dollars and they can exchange the money on their time at their bank, or incur any foreign transaction fees they might have should they choose to withdraw the funds at the ATM (with withdrawal limits I find this isn't always an option) 
I accept USD if the gents donate the same amount. For example $350 CAD ~ $350 USD (to me )
Toronto is fun and hope you will enjoy your trip
