If you are driving west from North Bay on highway 17 you would take highway 64 turn off south to Lavigne - about 15 minutes from turn off.  If you are driving north from Toronto on highway 400 / 69 you would take the highway 64 turn off at Alban located just south of Sudbury.  Lavigne would be less than an hours drive on highway 64. 

There are no commercial flights to Lavigne with the most convenient commercial airport being North Bay.  Here you can arrange rental car for the short drive.  North Bay is serviced by Bearskin Airlines and Air Canada Jazz allowing you to make connections with Toronto / Ottawa / and beyond.
