The time of occurrence data for 2373 fireball events predominantly observed from across Canada and documented in the Millman Fireball Archive is studied. The cumulative number of fireballs, arranged according to solar longitude, has been constructed and is interpreted in terms of an annual fireball activity profile. We find distinct enhancements in fireball activity at the times of the alpha-Capricornid, Perseid, Taurid, Leonid, chi-Orionid and Geminid meteor showers. Six other peaks in the activity profile are also identified but these do not correspond to any prominent cometary meteor shower. The strongest peak in the entire activity profile falls at solar longitude = 165 deg (September 7) and we suggest that it may be related to the "Group 3" meteorite stream identified by Halliday et al., (1990). A peak at solar longitude = 248 deg (November 30) is also tentatively identified with the "Group 4" stream of Halliday et al. In addition we also tentatively associate a fireball peak at solar longitude = 191 deg (October 4) with the so-called HC34, H-chondrite meteorite stream identified by Wolf et al., (1995) and linked to the Peekskill meteorite fall in October of 1992.
