The Ham licence is for operating on ham frequencies only. Many of the Ham portables can be modiifed to work on FRS / GMRS and private commercial frequencies, however this breaches the communications act as they are not type approved for that use.
That being said Ham radios that cover the 70 Cm. band can be easily modified and programmed for FRS and GMRS. Depending on the store they will ask to see a licence in order to purchase. Keep in mind it is illegal to operate on FRS at more than 500 mw. some GMRS freqs can be used up to 5 watts.
Be careful with some of the chinese radios, the quality is poor and some have been seized by CBSa as they are not DOC type approved.
www.radioworld.ca is a good spot for 70cm. ham radios.
