Ask your local florist for options that are locally grown and in season. Or have a bouquet made entirely of wildflowers.
Ask photographers what green products they offer. Enviro-friendly wedding albums? Prints using veggie-based dyes?
Rather than honeymoon at a destination that requires air travel, consider exploring beautiful areas within Canada.
Offer biodegradable wedding favours such as fancy teas in reusable containers or tree seedlings wrapped in burlap.
