If you homeschool long enough you will inevitably have people ask you if homeschooling is even legal. You can rest assured in all of Canada and most of the world, for that matter, it is indeed legal; however, it is important that you are aware of the laws and regulations governing your province.
I would encourage you to read through these articles so you can become well versed on the laws of your particular province.
I would highly recommend becoming a member of HSLDA Canada. The benefits are enormous and there is something to be said for the peace of mind it affords you. HSLDA will provide you will 1. Legal Services 2. Insurance Services and 3. General Services.
Please check them out and encourage other moms in your group to join. They fight for the good of all homeschoolers in Canada and we need to show our support. They have made it even easier now with very resonable monthly, yearly or 2 year payments.
