I am Dual rated in Canadaand have found that bonding is more common in the FW world in Canada. Most RW VFR jobs are seasonal so they can only expect the summer from you while most IFR jobs are longer term, hence the commitment. The commitment for IFR over here is usually a gentlemans agreement ie. we would like a year or 2 from you minimum type of thing. I haven't crossed anyone looking for a training bond in the IFR world, however I am rated in 61/76 so I stick to what I already have. As far as FW they want to bond the youg guys so they don't jump to a regional in a year, personally I don't work for any of these companies, I've had good success finding both FW and RW companies who will take me on a handshake. I know this is long and rambling but I hope it gives some insight to Canada for you.
