Eurocan, please try to get right information before posting.
You need 250 hrs to pass the IATRA exam, which is VERY easy (unlike the JAA one). I studied 3 days before sitting the IATRA whereas it took me a year to complete the JAR ATPL.
The 750 hrs requirement is only for sitting the Canadian ATPL exam which is also far away easier than the JAR one.
I started as F/O on the A320 in SE Asia with a Canadian CPL, IATRA and 300 hrs TT... (and A320 type rating of course)
